    Sensitivity to carcinogenesis in nude mice: skin tumors caused by transplacental exposure to ethylnitrosourea (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-11-12
    Description: Female athymic nude mice and their phenotypically normal littermates were exposed transplacentally to ethylnitrosourea. Skin tumors (papillomas and sebaceous adenomas) developed on the nude mice with an almost tenfold greater incidence than on their haired littermates. Skin tumors were also induced on nude mice but not haired controls by direct intraperitoneal treatment with ethylnitrosourea. These results indicate that nude mice have higher than normal susceptibility to carcinogenesis under some circumstances.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Anderson, L M -- Last-Barney, K -- Budinger, J M -- CA 08748/CA/NCI NIH HHS/ -- CA 22498/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1982 Nov 12;218(4573):682-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7134965" target="_blank"〉PubMed〈/a〉

    Rhodamine-123 selectively reduces clonal growth of carcinoma cells in vitro (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-12-10
    Description: Rhodamine-123, a cationic laser dye, markedly reduced the clonal growth of carcinoma cells but had little effect on nontumorigenic epithelial cells in vitro. This selective inhibitory effect of Rhodamine-123 on some carcinomas is unusual since known anticancer drugs, such as arabinosyl cytosine and methotrexate, have not been shown to exhibit such selectivity in vitro.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bernal, S D -- Lampidis, T J -- Summerhayes, I C -- Chen, L B -- New York, N.Y. -- Science. 1982 Dec 10;218(4577):1117-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7146897" target="_blank"〉PubMed〈/a〉

    Mice regrow the tips of their foretoes (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-08-20
    Description: Mice will replace the tip of a foretoe when it is amputated distal to the last interphalangeal joint. Amputation of the digit more proximal to the joint does not result in regrowth of the foretoe. Though this growth shares certain similarities with the epimorphic regeneration of amphibian limbs, the two processes are not the same. The regrowth reported here in mice is probably similar to the scattered clinical reports of fingertips regeneration in children, and presents a model system with which to explore the controls of wound healing and tissue reconstruction in mammals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Borgens, R B -- CA 20920/CA/NCI NIH HHS/ -- NS 18456/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 20;217(4561):747-50.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7100922" target="_blank"〉PubMed〈/a〉

    Radiosensitization of hypoxic tumor cells by depletion of intracellular glutathione (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-08-06
    Description: Depletion of glutathione in Chinese hamster ovary cells in vitro by diethyl maleate resulted in enhancement of the effect of x-rays on cell survival under hypoxic conditions but not under oxygenated conditions. Hypoxic EMT6 tumor cells were similarly sensitized in vivo. The action of diethyl maleate is synergistic with the effect of the electron-affinic radiosensitizer misonidazole, suggesting that the effectiveness of misonidazole in cancer radiotherapy may be improved by combining it with drugs that deplete intracellular glutathione.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bump, E A -- Yu, N Y -- Brown, J M -- CA-15201/CA/NCI NIH HHS/ -- CM-87207/CM/NCI NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 6;217(4559):544-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7089580" target="_blank"〉PubMed〈/a〉

    Deficiency of functional messenger RNA for a developmentally regulated beta-crystallin polypeptide in a hereditary cataract (1982)
    American Association for the Advancement of Science (AAAS)
    Details

    Description: The messenger RNA for a beta-crystallin polypeptide with a molecular size of 27 kilodaltons, first detected 5 to 10 days after birth in the normal mouse lens and the Nakano mouse cataract, was not detected in the Philly mouse cataract with translation in vitro. The heterozygous Philly lens had intermediate levels of the 27-kilodalton beta-crystallin polypeptide and exhibited delayed onset of the cataract. The deficiency of functional 27-kilodalton beta-crystallin messenger RNA is the earliest lesion reported yet for the Philly lens and points to a transcriptional or posttranscriptional developmental defect in this hereditary cataract.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carper, D -- New York, N.Y. -- Science. 1982 Jul 30;217(4558):463-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6178163" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1982-10-01
    Description: Mouse embryos were grown successfully in vitro from the blastocyst stage to the limb bud stage. Mouse blastocysts grown in vitro for 10 days showed blood circulation in the yilk sac, forelimb buds, and the primordia of liver, pancreas, and lungs. These characteristics are indicative of a developmental stage equivalent to one-half of the total gestation period in utero. Improvements in culture conditions from days 7 to 9 have made it feasible to culture mouse blastocysts beyond the early somite stage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, L T -- Hsu, Y C -- AM 19535/AM/NIADDK NIH HHS/ -- AM 28550/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1982 Oct 1;218(4567):66-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7123220" target="_blank"〉PubMed〈/a〉

    Receptors for maleylated proteins regulate secretion of neutral proteases by murine macrophages (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-11-05
    Description: Receptors for maleylated or acetylated proteins as well as for alpha-2-macroglobulin-protease complexes on macrophages serve as scavengers by mediating the uptake of macromolecules from the extracellular compartment. Described in this report is a novel function of these receptors on macrophages: regulation of neutral protease secretion. The binding of maleylated bovine serum albumin to macrophages triggered secretion of three neutral proteases: neutral caseinases, plasminogen activator, and cytolytic proteinase. Release of acid phosphatase, however, was not induced. An important biological consequence of protease secretion by macrophages, tumor-cytolysis, was also triggered by engagement of the receptor for maleylated bovine serum albumin. By contrast, the binding of alpha-2-macroglobulin-protease complexes to the macrophages suppressed secretion of all three proteases. Thus two receptors heretofore believed to serve principally as scavengers also regulate secretory functions of macrophages.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Johnson, W J -- Pizzo, S V -- Imber, M J -- Adams, D O -- New York, N.Y. -- Science. 1982 Nov 5;218(4572):574-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6289443" target="_blank"〉PubMed〈/a〉

    Description: Alkyl-Substituted gamma-butyrolactones were synthesized and tested for their convulsant and anticonvulsant actions in mice and guinea pigs. The alpha-substituted compounds, alpha, alpha-dimethyl-, and alpha-ethyl-alpha-methyl-gamma-butyrolactone were anticonvulsant compounds with a spectrum of activity similar to that of ethosuximide. In contrast, beta-substituted compounds were convulsant agents similar to picrotoxinin.

    alpha A-crystallin messenger RNA of the mouse lens: more noncoding than coding sequences (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-02-19
    Description: The 14S messenger RNA (1300 to 1500 nucleotides) for the alpha A chain of alpha-crystallin of the mammalian lens is nearly three times larger than required to code for the polypeptide that contains 173 amino acids. As a means of accounting for this anomaly, a complementary DNA clone for the mouse alpha A-crystallin messenger RNA was constructed in pBR322 and sequenced. Derivation of the protein sequence from the nucleic acid sequence showed that mouse alpha A-crystallin is similar to that of other organisms. The messenger RNA contains 536 nucleotides located on the 3' side of the coding region, excluding the polyadenylate stretch. This 3' sequence does not encode any other crystallin and has multiple termination codons in the three possible reading frames.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉King, C R -- Shinohara, T -- Piatigorsky, J -- New York, N.Y. -- Science. 1982 Feb 19;215(4535):985-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7156978" target="_blank"〉PubMed〈/a〉

    Tumor metastasis is not due to adaptation of cells to a new organ environment (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-01-08
    Description: Murine B16 melanoma cells were adapted for lung survival and growth by allowing them to attach to Bio-Carrier beads and injecting the beads intravenously into normal mice. The beads lodged mechanically in the microcirculation of the lung. When the melanoma cells had grown into visible tumors from the arrested beads, the tumors were removed and the cells were dispersed, cultured to remove normal cells, and reattached to new beads. The process was repeated nine times. Previously another B16 subline was injected intravenously as a suspension of separate tumor cells. Those cells that survived and colonized the lungs were harvested, cultured, and injected again. This selection process was also repeated nine times. Only the subline that was injected in suspension was more metastatic than the parental line, indicating that metastasis involves selection of preexistent metastatic cells and is not an adaptive process by which all cells gradually acquire the ability to grow at particular organ sites.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nicolson, G L -- Custead, S E -- R01-CA28867/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1982 Jan 8;215(4529):176-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7053568" target="_blank"〉PubMed〈/a〉

    Increased axonal proteolysis in myelin-deficient mutant mice (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-02-19
    Description: Protein degradation within retinal ganglion cell axons in vitro is 50 to 110 percent faster than normal in mutant mice exhibiting deficiencies of myelin in the central nervous system. Proteolysis is increased proximally and distally within retinal ganglion cell axons of mice carrying the jumpy mutation or its allele, myelin synthesis deficiency, and is increased distally within those axons of quaking mice. The proteolytic defect is axon (neuron)-specific since the rate of protein degradation within glial cells is normal. Increased axonal proteolysis does not bear a simple relation to hypomyelination since shiverer, another mouse mutant deficient in central myelin, displayed normal rates of axonal protein degradation under the same conditions. These observations suggest an abnormal axon-glial interaction in mice with primary glial defects and raise the possibility that the functioning of histologically normal axons (neurons) may be altered in dysmyelinating diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nixon, R A -- NS15494/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Feb 19;215(4535):999-1001.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7156980" target="_blank"〉PubMed〈/a〉

    Somatic mutation in genes for the variable portion of the immunoglobulin heavy chain (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-04-16
    Description: The size of the gene pool potentially encoding antibodies to p-azophenyl arsonate has been examined. A heavy chain-specific full-length complementary DNA clone has been constructed with the use of messenger RNA from a hybridoma that produces antibodies to the arsonate hapten and bears nearly a full complement of the determinants comprising the cross-reactive idiotype (CRI). The sequences of both the complementary DNA clone and the corresponding immunoglobulin heavy chain have been independently determined. A probe for the variable region gene was prepared from the original heavy chain complementary DNA clone and used to analyze, by Southern filter hybridization, genomic DNA from both A/J (CRI positive) and BALB/c (CRI negative) mice. Approximately 20 to 25 restriction fragments containing "germline" variable region gene segments were detected in both strains, and many are shared by both, Since 35 CRI-positive heavy chains have been partially sequenced thus far and 31 are different, the results of the hybridization analysis suggest that somatic mutation events involving the variable region gene segments of the heavy chain play a role in the origin of the amino acid sequence diversity seen in this system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sims, J -- Rabbitts, T H -- Estess, P -- Slaughter, C -- Tucker, P W -- Capra, J D -- A112127/PHS HHS/ -- AI-06020/AI/NIAID NIH HHS/ -- AI18016/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1982 Apr 16;216(4543):309-11.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6801765" target="_blank"〉PubMed〈/a〉

    Evidence for the clonal origin of spontaneous metastases (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-07-23
    Description: A cultured cell line of the K-1735 melanoma was x-irradiated to induce chromosome breakage and rearrangements and then was implanted into the footpads of syngenic C3H mice. Spontaneous lung metastases were isolated from different animals, established in culture as individual lines, and then karyotyped. Within certain metastases, the same chromosomal abnormality (or abnormalities) (recombinant chromosomes) was found in all the cells examined. Most metastases differed from one another in that they exhibited characteristic combinations of chromosomal markers. These findings indicated that the metastases were clonal and that they probably originated from different progenitor cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Talmadge, J E -- Wolman, S R -- Fidler, I J -- N01-CO-75380/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 1982 Jul 23;217(4557):361-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6953592" target="_blank"〉PubMed〈/a〉

    Autoradiographic identification of ornithine decarboxylase in mouse kidney by means of alpha-[5-14C]difluoromethylornithine (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-07-02
    Description: alpha-Difluoromethylornithine is an enzyme-activated irreversible inhibitor of ornithine decarboxylase that forms a covalent bond with the enzyme. When alpha-[5-14C]difluoromethylornithine was administered to androgen-treated mice, only ornithine decarboxylase became labeled. Autoradiographic examination of kidney, liver, and brain indicated much more extensive incorporation of labeled difluoromethylornithine into kidney protein than into the protein of the other tissues. Such incorporation was greatly reduced by prior treatment of the mice with cycloheximide. These results correlate with the presence of ornithine decarboxylase activity which is much higher in the kidney than in the other tissues and is lost rapidly when protein synthesis is inhibited. The binding of this drug in vivo, therefore, is useful for determining the distribution of ornithine decarboxylase. The enzyme was predominantly located in the proximal tubule cells of the kidney in androgen-treated mice.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pegg, A E -- Seely, J -- Zagon, I S -- 1T32HL-07223/HL/NHLBI NIH HHS/ -- CA 18138/CA/NCI NIH HHS/ -- DA-01618/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 1982 Jul 2;217(4554):68-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6806900" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1982-07-16
    Description: The ability of antiserum against murine L1210 leukemia to remove residual leukemia cells from murine bone marrow was investigated. Leukemic marrow was treated in vitro with antiserum and complement and used to hematologically reconstitute mice that had been irradiated with doses lethal to bone marrow. Following infusion of treated leukemic marrow, normal marrow returned without evidence of leukemia. More than 90 percent of the animals have survived for 11 months without untoward effects, suggesting that the technique may be of use in the treatment of acute leukemia in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Trigg, M E -- Poplack, D G -- New York, N.Y. -- Science. 1982 Jul 16;217(4556):259-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7046048" target="_blank"〉PubMed〈/a〉

    Description: Large numbers of granulocytes can be collected repeatedly from the supernatant medium of long-term cultures of mouse bone marrow cells. A constant relationship was found between the number of adherent hematopoietic stem cells and the lifetime cell production per culture. The data indicate that there is a limit to the proliferative capacity of normal and of irradiated stem cells. A similar limitation was found in the production of marked granulocytes from clonal cultures of "beige" C57 (bg/bgJ) stem cells placed in limiting dilutions into stromal culture layers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reincke, U -- Hannon, E C -- Rosenblatt, M -- Hellman, S -- CA 10941/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1982 Mar 26;215(4540):1619-22.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7071580" target="_blank"〉PubMed〈/a〉

    In vivo identification of the transforming gene product of simian sarcoma virus (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-12-10
    Description: Simian sarcoma virus (SSV) deletion mutants were constructed from a molecular clone containing the entire infectious provirus. Transfection analysis of these mutants localized the SSV transforming gene to a small region of the viral genome encompassing its cell-derived sequence (v-sis). Antiserum to a peptide synthesized on the basis of the predicted amino acid sequence of the SSV transforming gene detected a 28,000-dalton protein that was specifically expressed in SSV transformed cells and that corresponded in size to that predicted from the v-sis coding sequence. The v-sis gene product designated p28sis was not a phosphoprotein, nor did it possess detectable protein kinase activity. These findings distinguish p28sis from a number of other retroviral onc proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Robbins, K C -- Devare, S G -- Reddy, E P -- Aaronson, S A -- New York, N.Y. -- Science. 1982 Dec 10;218(4577):1131-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6293053" target="_blank"〉PubMed〈/a〉

    Noise-induced hearing loss can alter neural coding and increase excitability in the central nervous system (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-06-18
    Description: Responses of auditory neurons in the inferior colliculi of mice were studied longitudinally before and shortly after each animal was exposed to intense noise. Noise exposure caused expected losses in auditory sensitivity, but in 31 percent of the neurons studied, unexpected alterations of temporal patterns of action potentials were observed: certain suprathreshold stimuli that had evoked only transient "onset" responses or inhibition of spontaneous discharges prior to noise exposure came to elicit sustained excitation after exposure. Thus, noise-induced hearing loss can be associated with increases in neural responsivity and alterations of normal neural coding processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Willott, J F -- Lu, S M -- New York, N.Y. -- Science. 1982 Jun 18;216(4552):1331-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7079767" target="_blank"〉PubMed〈/a〉

    Recovery of olfactory function after bilateral bulbectomy (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-04-16
    Description: Mice were trained to discriminate between scented and unscented air. After olfactory bulbs were removed, discrimination was lost, but returned with the formation of synaptic connections between regenerated primary olfactory neurons and the cortex of the forebrain. The acquisition of a second olfactory-mediated task by long-term bulbectomized mice and controls was indistinguishable. The results emphasize the plasticity of the nervous system, correlate the presence of neural connections between olfactory mucosa and forebrain with the recovery of olfactory function, suggest that olfactory-mediated memory resides at least in part outside the olfactory bulbs, and demonstrate that the bulbs are not required for the acquisition of olfactory tasks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wright, J W -- Harding, J W -- NS 13976/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Apr 16;216(4543):322-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7063891" target="_blank"〉PubMed〈/a〉

    Description: Mice infected with Trypanosoma rhodesiense were treatment concurrently with cis-diamminedichloroplatinum (II) (DDP), disulfiram, and hydration. Most of the mice (92.5 percent) were cured; inoculation of blood or suspensions of brain or heart from these animals did not produce disease in recipient mice. The dose of DDP needed to eliminate the trypanosomes, 3 milligrams per kilogram of body weight per day for 7 days, was lethally toxic unless the animals received disulfiram orally and subcutaneous injections of physiologic saline, which reduced the acute renal necrosis caused by DDP alone. Some mild to moderate reversible renal damage was noted upon pathologic examination of the treated mice.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wysor, M S -- Zwelling, L A -- Sanders, J E -- Grenan, M M -- New York, N.Y. -- Science. 1982 Jul 30;217(4558):454-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7201165" target="_blank"〉PubMed〈/a〉

    Description: Gridlike patterns of differing cell density were observed in evenly seeded cell monolayers. Such patterns were obtained in five of six cell lines tested, suggesting widespread occurrence. The mechanism appears to involve small, transient temperature changes related to incubator tray structure. The very short time course of appearance of the patterns implicates attachment rather than growth as the critically affected factor. Impaired adhesion or directed sedimentation resulting from thermally induced microcurrents in the medium are the two most likely mechanisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Adler, E M -- Flunk, L J -- Mullin, J M -- Kleinzeller, A -- 2 T32 GM07229-07/GM/NIGMS NIH HHS/ -- AM 12619-13/AM/NIADDK NIH HHS/ -- HL07027-07/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 27;217(4562):851-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7048529" target="_blank"〉PubMed〈/a〉

Mouse NIH 3T3 cells freshly transfected with either cloned Moloney sarcoma proviral DNA or cellular DNA's derived from virally transformed cells induced tumors when injected into athymic nu/nu mice. Tumors were also induced by cells transfected with DNA from two tumor-derived and one chemically transformed human cell lines. The mouse tumors induced by human cell line DNA's contained human DNA sequences, and DNA derived from these tumors was capable of inducing both tumors and foci on subsequent transfection.

Addition of an excess of horse antiserum to the venom resulted in a significant acceleration of the dissociation reaction. Similarly, a monoclonal antibody against the toxin accelerated dissociation of the receptor-toxin complex. The results indicate that specific antibody binding destabilizes the toxin-receptor complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boulain, J C -- Menez, A -- New York, N.Y. -- Science. 1982 Aug 20;217(4561):732-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7100919" target="_blank"〉PubMed〈/a〉

    Interference with dimethylhydrazine induction of colon tumors in mice by epsilon-aminocaproic acid (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-05-28
    Description: The antifibrinolytic agent epsilon-aminocaproic acid given in the drinking water to Swiss ICR/Ha mice significantly counteracted the appearance of colorectal tumors induced by 21 weekly infections of 1,2-dimethylhydrazine. The drug affected both the number and the location of the tumors and, in some animals, altogether prevented their appearance. The low concentrations of epsilon-aminocaproic acid in the plasma of four control mice given the agent labeled with carbon-14 for 3 days suggest that the effect may depend not on inhibition of plasminogen activator activity, but on interference with the binding of some substance to the strong lysine binding site of plasminogen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Corasanti, J G -- Hobika, G H -- Markus, G -- New York, N.Y. -- Science. 1982 May 28;216(4549):1020-1.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6805074" target="_blank"〉PubMed〈/a〉

    Cellular transforming genes (1982)

    Details
    Publication Date: 1982-08-27
    Description: Cellular genes potentially capable of inducing oncogenic transformation have been identified by homology to the transforming genes of retroviruses and by the biological activity of cellular DNA's in transfection assays. DNA's of various tumors induce transformation with high efficiencies, indicating that oncogenesis can involve dominant genetic alterations resulting in activation of cellular transforming genes. The identification and characterization of cellular transforming genes and their possible involvement in naturally occurring cancers, is discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cooper, G M -- New York, N.Y. -- Science. 1982 Aug 27;217(4562):801-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6285471" target="_blank"〉PubMed〈/a〉

    Anticonvulsant action of excitatory amino acid antagonists (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-05-21
    Description: Compounds that antagonize neuronal excitation induced by dicarboxylic amino acids were tested in two animal models of epilepsy, namely sound-induced seizures in DBA/2 mice and threshold pentylenetetrazol seizures in Swiss mice. Sound-induced seizures could be prevented by intracerebroventricular injection of compounds that block excitation due to N-methyl-D-aspartic acid. The most potent such compound, 2-amino-7-phosphonoheptanoic acid, was anticonvulsant in both test systems when given either intraperitoneally or intracerebroventricularly. Specific antagonists of excitation that is caused by amino acids provide a new class of anticonvulsant agents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Croucher, M J -- Collins, J F -- Meldrum, B S -- New York, N.Y. -- Science. 1982 May 21;216(4548):899-901.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7079744" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1982-09-10
    Description: Whether neoplasms are unicellular or multicellular in their origin, the process of tumor evolution and progression can rapidly generate biological diversity. Metastases result from the survival and proliferation of specialized subpopulations of cells within the parent tumor. Metastases may have a clonal origin and different metastases may develop from different progenitor cells. However, as with the primary tumor, the origin of metastases is unimportant since the process of tumor evolution and progression can generate biological diversity within and among different metastatic foci.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fidler, I J -- Hart, I R -- N01-CO-75380/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 1982 Sep 10;217(4564):998-1003.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7112116" target="_blank"〉PubMed〈/a〉

    Description: Mouse and human placental tissue contains a large number of mononuclear phagocytes. These cells, isolated from placenta, were shown to produce the multifaceted immune factor interleukin-1. Activity in the supernatants of 48-hour mononuclear phagocyte cultures was associated with a 12,000- to 18,000-dalton protein, consistent with known interleukin-1 characteristics. Stimulation of phagocytosis with latex beads increased the production and release of interleukin-1 from these placental cells, which may be a useful source of this protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Flynn, A -- Finke, J H -- Hilfiker, M L -- CA 24474/CA/NCI NIH HHS/ -- CA 34107/CA/NCI NIH HHS/ -- RR 00210/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1982 Oct 29;218(4571):475-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6981846" target="_blank"〉PubMed〈/a〉

    Description: The active exogenous murine leukemia virus sequences of mouse cells growing in culture are preferentially digested by deoxyribonuclease I in metaphase chromosomes. As determined by nuclear nick translation, all of the gene sequences of these cells active during interphase are in a deoxyribonuclease I-sensitive conformation during metaphase. This method of nick translation can therefore be used to label chromosomes in situ in order to visualize the active regions of the genome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gazit, B -- Cedar, H -- Lerer, I -- Voss, R -- GM 20483/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 13;217(4560):648-50.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6283640" target="_blank"〉PubMed〈/a〉

    Publication Date: 1982-05-28
    Description: Mitogenic stimulation of mouse lymphocytes results in two sequential intracellular alkalinizations. The first shift of intracellular pH from 7.18 to 7.35 coincides with early biochemical events following mitogenic stimulation. The second alkalinization begins 12 hours after stimulation and rises in parallel with the rate of thymidine incorporation. The results suggest that intracellular alkalinization following stimulation may play a key role in the enhancement of cellular activation and mitogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gerson, D F -- Kiefer, H -- Eufe, W -- New York, N.Y. -- Science. 1982 May 28;216(4549):1009-10.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6281887" target="_blank"〉PubMed〈/a〉

    Identification of a BALB/c H-2Ld gene by DNA-mediated gene transfer (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-02-05
    Description: Gene transfer and immunoselection were used in the identification of a BALB/c genomic clone containing an H-2Ld gene (clone 27.5). Transformation of thymidine kinase-negative C3H mouse L cells with the cloned 27.5 DNA together with the herpes simplex virus tk gene produced transformants expressing Ld molecules detected by radioimmune assay with monoclonal hybridoma antibodies to Ld antigens. The foreign Ld gene products expressed by cloned mouse L cell transformants were shown to be virtually indistinguishable from BALB/c spleen Ld molecules by two-dimensional electrophoretic analysis of H-2Ld immunoprecipitates. These results indicate that the genomic clone 27.5 contains a functional BALB/c H-2Ld gene and demonstrate the usefulness of this approach for identifying the gene products encoded by cloned genes which are members of a multigene family. Furthermore, the ability to place cell-surface recognition molecules on the surfaces of foreign cells provides a powerful opportunity for functional analyses of these molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goodenow, R S -- McMillan, M -- Orn, A -- Nicolson, M -- Davidson, N -- Frelinger, J A -- Hood, L -- CA 22662/CA/NCI NIH HHS/ -- CA 26199/CA/NCI NIH HHS/ -- GM 06965/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1982 Feb 5;215(4533):677-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7058331" target="_blank"〉PubMed〈/a〉

This indicates that cells can discriminated between different ribosomal RNA's.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lavelle, D -- Ostro, M J -- Giacomoni, D -- GM 27935/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1982 Jul 2;217(4554):59-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6178157" target="_blank"〉PubMed〈/a〉

    Tumor cell-platelet aggregation: induced by cathepsin B-like proteinase and inhibited by prostacyclin (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-08-06
    Description: The ability of tumor cells to metastasize may be related to their ability to promote aggregation of host platelets. The use of inhibitors of cysteine proteinases resulted in parallel inhibition of B16 amelanotic melanoma-induced platelet aggregation and of a cathepsin B activity. The antimetastatic agent prostacyclin inhibited platelet aggregation induced by the tumor cells and by papain, a cathepsin B-mimicking agent.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Honn, K V -- Cavanaugh, P -- Evens, C -- Taylor, J D -- Sloane, B F -- CA29405/CA/NCI NIH HHS/ -- CA29997/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 6;217(4559):540-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7046053" target="_blank"〉PubMed〈/a〉

    DNA sequence of the gene encoding the E alpha Ia polypeptide of the BALB/c mouse (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-12-17
    Description: A 3.4-kilobase DNA fragment containing the gene coding for the E alpha chain of an Ia (I region-associated) antigen from the BALB/c mouse has been sequenced. It contains at least three exons, which correlate with the major structural domains of the E alpha chain-the two external domains alpha 1 and alpha 2, and the transmembrane-cytoplasmic domain. The coding sequence of the mouse E alpha gene shows striking homology to its counterpart at the DNA and protein levels. The translated alpha 2 exon demonstrates significant similarity to beta 2-microglobulin, to immunoglobulin constant region domains, and to certain domains of transplantation antigens. These observations and those of others suggest that the Ia antigen, transplantation antigen, and immunoglobulin gene families share a common ancestor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McNicholas, J -- Steinmetz, M -- Hunkapiller, T -- Jones, P -- Hood, L -- New York, N.Y. -- Science. 1982 Dec 17;218(4578):1229-32.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6815800" target="_blank"〉PubMed〈/a〉

    Opioid-like analgesia in defeated mice (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-03-19
    Description: Mice exposed to repeated attacks by other mice showed decreased nociception in response to radiant heat focused on their tails. This form of analgesia was blocked by centrally acting opiate antagonists and was not observed in morphine-tolerant mice; furthermore, mice repeatedly subjected to defeat. Mice of the CXBK strain, which respond weakly to morphine, displayed only moderate analgesia following defeat. These findings suggest that endogenous opioid-mediated analgesic mechanisms are readily activated by situations involving biologically significant forms of stress, such as defeat.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miczek, K A -- Thompson, M L -- Shuster, L -- AA-05122/AA/NIAAA NIH HHS/ -- DA-02632/DA/NIDA NIH HHS/ -- DA-05054/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 1982 Mar 19;215(4539):1520-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7199758" target="_blank"〉PubMed〈/a〉

    Description: The sequence of a gene, denoted 27.5, encoding a transplantation antigen for the BALB/c mouse has been determined. Gene transfer studies and comparison of the translated sequence with the partial amino acid sequence of the Ld transplantation antigen establish that gene 27.5 encodes an Ld polypeptide. A comparison of the gene 27.5 sequence with several complementary DNA sequences suggests that the BALB/c mouse may contain a number of closely related L-like genes. Gene 27.5 has eight exons that correlate with the structural domains of the transplantation antigen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moore, K W -- Sher, B T -- Sun, Y H -- Eakle, K A -- Hood, L -- 1 T32 GM07616/GM/NIGMS NIH HHS/ -- GM 06965/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1982 Feb 5;215(4533):679-82.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7058332" target="_blank"〉PubMed〈/a〉

    Autoantibodies to insulin receptor spontaneously develop as anti-idiotypes in mice immunized with insulin (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-04-30
    Description: Mice immunized with insulin developed antibodies to both insulin and the insulin receptor. The antibodies to insulin receptor displaced labeled insulin from insulin receptors and mimicked the actions of insulin in stimulating the oxidation of glucose and its incorporation into lipids, and in inhibiting lipolysis. The antibodies to insulin receptor could be blocked by or bound to the antibodies to insulin, and therefore were identified as anti-idiotypes. Thus, immunization against a hormone may activate spontaneously an idiotype-anti-idiotype network resulting in antibodies to the hormone receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shechter, Y -- Maron, R -- Elias, D -- Cohen, I R -- AM 26766/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1982 Apr 30;216(4545):542-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7041258" target="_blank"〉PubMed〈/a〉

    Virus-induced alterations in homeostasis: alteration in differentiated functions of infected cells in vivo (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-12-10
    Description: The noncytopathic lymphocytic choriomeningitis virus displays a tropism for the anterior lobe of the murine pituitary gland. Virus replicates in cells that make growth hormone. This results in a diminished synthesis of growth hormone with a concomitant clinical picture of retarded growth and hypoglycemia. However, there is no morphologic evidence of either cell necrosis or inflammation in the anterior lobe of the pituitary. Hence, during infection in vivo, a noncytopathic virus may turn off the "differentiation" or "luxury" function of a cell while not killing that cell (loss of vital function). This is turn can disrupt homeostasis and cause disease. This model illustrates a novel way whereby viruses may cause disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Oldstone, M B -- Sinha, Y N -- Blount, P -- Tishon, A -- Rodriguez, M -- von Wedel, R -- Lampert, P W -- AI-09484/AI/NIAID NIH HHS/ -- CA-33448/CA/NCI NIH HHS/ -- NS-12428/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Dec 10;218(4577):1125-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7146898" target="_blank"〉PubMed〈/a〉

    Gut reactions of radioactive nitrite after intratracheal administration in mice (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-07-09
    Description: Intratracheal administration to mice of radioactive nitrite labeled with nitrogen-13 (13NO2-) (half-life, 9.96 minutes) in dosages that do not cause pharmacological perturbation reveals that oxidative and reductive reactions occur in different organs. Oxidation of 13NO2- to radioactive nitrate (13NO3-) predominates in the blood and liver. Reduction of 13NO2- occurs in those mice that harbor intestinal microflora; this reduction does not occur in germ-free mice. The intestinal reduction products include ammonium, glutamate, glutamine, and urea. With a detection limit of about 0.01 percent of the instilled nitrogen-13, no labeled nitrosamines were detected within 30 minutes. Reduced nitrogen-13 is transported out of the intensive into the circulatory system and appears in the urine along with 13NO3-. The biological half-period for 13NO2- destruction is about 7 minutes, and both oxidation and reduction products are formed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thayer, J R -- Chasko, J H -- Swartz, L A -- Parks, N J -- New York, N.Y. -- Science. 1982 Jul 9;217(4555):151-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6211766" target="_blank"〉PubMed〈/a〉

    Nerve growth factor attenuates neurotoxic effects of taxol on spinal cord-ganglion explants from fetal mice (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-07-23
    Description: Most neurons in organotypic cultures of dorsal root ganglia from 13-day-old fetal mice require high concentrations of nerve growth factor for survival during the first week after explanation. These nerve growth factor-enhanced sensory neurons mature and innervate the dorsal regions of attached spinal cord tissue even after the removal of exogenous growth factor after 4 days. In cultures exposed for 4 days to nerve growth factor and taxol (a plant alkaloid that promotes the assembly of microtubules) and returned to medium without growth factor, greater than 95 percent of the ganglionic neurons degenerated and the spinal cord tissues were reduced almost to monolayers. In contrast, when the recovery medium was supplemented with nerve growth factor, the ganglionic neurons and dorsal (but not ventral) cord tissue survived remarkably well. Dorsal cord neurons do not normally require an input from dorsal root ganglia for long-term maintenance in vitro, but during and after taxol exposure they become dependent for survival and recovery on the presence of neurite projections from nerve growth-factor-enhanced dorsal root ganglia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Peterson, E R -- Crain, S M -- NS-14990/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Jul 23;217(4557):377-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6124041" target="_blank"〉PubMed〈/a〉

    Description: Lifelong dietary restriction beginning at 3 to 6 weeks of age in rodents is known to decelerate the rate of aging, increase mean and maximum life-spans, and inhibit the occurrence of many spontaneous cancers. Little is known about the effects of dietary restriction started in middle age. In the experiments now reported the food intake of 12- to 13-month-old mice of two long-lived strains was restricted by using nutrient-enriched diets in accordance with the concept of "undernutrition without malnutrition." The mice on the restricted diet averaged 10 to 20 percent increases in mean and maximum survival times compared to the control mice. Spontaneous lymphoma was inhibited by the food restriction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weindruch, R -- Walford, R L -- AG-00424/AG/NIA NIH HHS/ -- CA-26164/CA/NCI NIH HHS/ -- CA-9030/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1982 Mar 12;215(4538):1415-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7063854" target="_blank"〉PubMed〈/a〉

    Morphologic effect of dimethyl sulfoxide on the blood-brain barrier (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-07-09
    Description: Dimethyl sulfoxide (DMSO) opens the blood-brain barrier of mice to the enzymatic tracer horseradish peroxidase. A single injection of horseradish peroxidase in 10 to 15 percent DMSO into the tail vein along with 10 to 15 percent DMSO delivered intraperitoneally allowed horseradish peroxidase to fill the extracellular clefts throughout the brain within 2 hours. In the absence of DMSO, peroxidase failed to enter brain parenchyma except through the circumventricular organs. Opening of the blood-brain barrier by DMSO is reversible. Dimethyl sulfoxide stimulated the pinocytosis of horseradish peroxidase by the cerebral endothelium; the peroxidase was then directed to lysosomal dense bodies for degradation. Vesicular transport of horseradish peroxidase from the luminal to the abluminal wall of the endothelial cell was not observed. Dimethyl sulfoxide did not alter the morphology of endothelial cells or brain parenchyma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Broadwell, R D -- Salcman, M -- Kaplan, R S -- NS18030-01/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Jul 9;217(4555):164-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7089551" target="_blank"〉PubMed〈/a〉

    Phosphorylation of myosin light chains in mouse fast-twitch muscle associated with reduced actomyosin turnover rate (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-08-27
    Description: Phosphorylation of the 18,000-dalton light chains of the fast-twitch myosin in mouse extensor digitorum longus muscles was correlated with reduction in the rate of the actomyosin adenosinetriphosphatase in vivo, but neither of these changes occurred in the soleus muscle. These results suggest that actomyosin interactions can be down-regulated by a reversible covalent modification of myosin light chains, that a mechanism for thick-filament regulation occurs in vertebrate skeletal muscle, and that the expression of this regulation may be limited to a specific fiber type.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crow, M T -- Kushmerick, M J -- New York, N.Y. -- Science. 1982 Aug 27;217(4562):835-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6285472" target="_blank"〉PubMed〈/a〉

    Mouse c-myc oncogene is located on chromosome 15 and translocated to chromosome 12 in plasmacytomas (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-12-24
    Description: Hybridization studies with viral oncogene probes indicate that c-myc, the cellular gene homologous to the transforming gene of avian myelocytomatosis virus, resides on mouse chromosome 15 and in many plasmacytomas is translocated to the antibody heavy chain gene locus on chromosome 12. The transcriptional orientation of the translocated c-myc sequence is opposite the orientation of the adjacent C alpha gene that codes for the heavy chain of immunoglobulin A. The translocated c-myc sequence is not the same oncogene detected in urine plasmacytomas by the NIH-3T3 cell transformation assay.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crews, S -- Barth, R -- Hood, L -- Prehn, J -- Calame, K -- New York, N.Y. -- Science. 1982 Dec 24;218(4579):1319-21.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7146913" target="_blank"〉PubMed〈/a〉

    Publication Date: 1982-10-29
    Description: Monoclonal antibodies specific for 5-bromodeoxyuridine have been produced and applied in detecting low levels of DNA replication on a cell-by-cell basis in vitro. The immunoglobulin-producing hybridomas were derived from spleen cells of mice immunized with a conjugate of iodouridine and ovalbumin. The cells were fused with the plasmacytoma line SP2/0Ag14. The antibodies produced are highly specific for bromodeoxyuridine and iododeoxyuridine and do not cross-react with thymidine. DNA synthesis in cultured cells exposed to bromodeoxyuridine for as short a time as 6 minutes can be detected easily and rapidly by an immunofluorescent staining method and quantitated by flow cytometry.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gratzner, H G -- 5R26CA-15480-09/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1982 Oct 29;218(4571):474-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7123245" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-05-28
    Description: The influence of the H-2 histocompatibility complex on glucocorticoid receptor levels, and the biochemical response of glucocorticoid action measured as the degree of inhibition of prostaglandin production, has been studied in the mouse thymus and lung. The B10A (H-2a) strain of mice has significantly higher glucocorticoid receptor levels and a significantly greater biochemical response to glucocorticoid than the B10 (H-2b) strain, which differs from B10A within the H-2 complex only. Thus, the anti-inflammatory hormone response of glucocorticoids is correlated to hormone receptor level, both of which are influenced by the H-2 locus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gupta, C -- Goldman, A -- DE-0541/DE/NIDCR NIH HHS/ -- DE-4622/DE/NIDCR NIH HHS/ -- DE-5592/DE/NIDCR NIH HHS/ -- New York, N.Y. -- Science. 1982 May 28;216(4549):994-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7079749" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-09-10
    Description: Foreign gene sequences were retained in two adult mice (out of 62 analyzed) from fertilized eggs injected with a recombinant plasmid containing the human beta-globin genomic region and the herpes simplex viral thymidine kinase gene. The intact human and viral genes were found in DNA of one of the animals and, in the other, at least part of the human globin gene was present. The latter individual transmitted these sequences to its progeny in a Mendelian ration. Thus, human DNA may be incorporated into the germ line of mice for in vivo studies of regulation of gene expression in development, genetic diseases, and malignancy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Steward, T A -- Wagner, E F -- Mintz, B -- CA-60927/CA/NCI NIH HHS/ -- HD-01646/HD/NICHD NIH HHS/ -- RR-05539/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1982 Sep 10;217(4564):1046-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6287575" target="_blank"〉PubMed〈/a〉

    Virus-induced corticosterone in hypophysectomized mice: a possible lymphoid adrenal axis (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-12-24
    Description: Infection of hypophysectomized mice with Newcastle disease virus caused a time-dependent increase in corticosterone and interferon production. Prior treatment with dexamethasone completely inhibited the virus-induced elevation in corticosterone concentration, but did not significantly alter the interferon response. Lymphocytes appear to be the most likely source of an adrenocorticotropin-like substance that is responsible for the increased corticosterone, since spleen cells from the virus-infected, but not from control or dexamethasone-treated, hypophysectomized mice showed positive immunofluorescence with antibody to adrenocorticotropin-(1-13 amide). Thus the adrenocorticotropin-like material and interferon appear to be coordinately induced the differentially controlled products of different genes. These findings strongly suggest the existence of a lymphoid-adrenal axis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, E M -- Meyer, W J -- Blalock, J E -- AM30046/AM/NIADDK NIH HHS/ -- HL20201/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1982 Dec 24;218(4579):1311-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6183748" target="_blank"〉PubMed〈/a〉

    Description: Viruses that infect ependyma cause ependymitis in humans and hydrocephalus in experimental animals. We report that reovirus type 1 (which induces hydrocephalus in mice) binds to the surface of isolated human and murine ciliated ependymal cells. With the use of recombinant viral clones, the binding property was mapped to the type 1 viral hemagglutinin, which also determines in vivo the affinity of reovirus type 1 for ependyma. Mumps virus, measles virus, parainfluenza type 3, and herpes simplex virus type 1 bind to murine ependyma cells, whereas reovirus type 3, herpes simplex virus type 2, and poliovirus type 2 do not.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tardieu, M -- Weiner, H L -- 1K07-NS00237/NS/NINDS NIH HHS/ -- NSAI-16998/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Jan 22;215(4531):419-21.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6276976" target="_blank"〉PubMed〈/a〉

    Description: Biochemical, electrophysiological, and pharmacological evidence supporting a role for cholinergic dysfunction in age-related memory disturbances is critically reviewed. An attempt has been made to identify pseudoissues, resolve certain controversies, and clarify misconceptions that have occurred in the literature. Significant cholinergic dysfunctions occur in the aged and demented central nervous system, relationships between these changes and loss of memory exist, similar memory deficits can be artificially induced by blocking cholinergic mechanisms in young subjects, and under certain tightly controlled conditions reliable memory improvements in aged subjects can be achieved after cholinergic stimulation. Conventional attempts to reduce memory impairments in clinical trials hav not been therapeutically successful, however. Possible explanations for these disappointments are given and directions for future laboratory and clinical studies are suggested.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bartus, R T -- Dean, R L 3rd -- Beer, B -- Lippa, A S -- New York, N.Y. -- Science. 1982 Jul 30;217(4558):408-14.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7046051" target="_blank"〉PubMed〈/a〉

    Description: Evidence for the binding of 5,5-diphenylhydantoin and glucocorticoids to a common receptor is presented for pulmonary and hepatic cytosols and thymocytes of A/J female mice. The 5,5-diphenylhydantoin-protein complex is absorbed by DNA cellulose, and is incorporated into nuclei, 5,5-Diphenylhydantoin, like glucocorticoids, inhibits the production of prostaglandins in thymocytes.

    Details
    Publication Date: 1982-01-15
    Description: Exposure of mice to the herbicide 2,4-dichlorophenyl-p-nitrophenyl ether during gestation produces abnormalities that are not readily apparent at birth but become obvious as the pups mature. By 2 weeks after birth there are severe intraorbital defects resulting from destruction of the Harderian glands behind the eyes. This effect is noticeable only postnatally because the Harderian gland does not grow or function until after birth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gray, L E Jr -- Kavlock, R J -- Chernoff, N -- Ferrell, J -- McLamb, J -- Ostby, J -- New York, N.Y. -- Science. 1982 Jan 15;215(4530):293-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7053576" target="_blank"〉PubMed〈/a〉

    Is the acetylcholine receptor a rabies virus receptor? (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-01-08
    Description: Rabies virus was found on mouse diaphragms and on cultured chick myotubes in a distribution coinciding with that of the acetylcholine receptor. Treatment of the myotubes with alpha-bungarotoxin and d-tubocurarine before the addition of the virus reduced the number of myotubes that became infected with rabies virus. These findings together suggest that acetylcholine receptors may serve as receptors for rabies virus. The binding of virus to acetylcholine receptors, which are present in high density at the neuromuscular junction, would provide a mechanism whereby the virus could be locally concentrated at sites in proximity to peripheral nerves facilitating subsequent uptake and transfer to the central nervous system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lentz, T L -- Burrage, T G -- Smith, A L -- Crick, J -- Tignor, G H -- AI 11132/AI/NIAID NIH HHS/ -- AI 12541/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1982 Jan 8;215(4529):182-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7053569" target="_blank"〉PubMed〈/a〉

    Monoclonal antibodies to hypothalamic growth hormone-releasing factor with picomoles of antigen (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-11-26
    Description: Monoclonal antibodies specific for rat hypothalamic growth hormone-releasing factor (rGRF) have been produced by in vitro immunization of mouse spleen cells with less than 1 nanomole of rGRF in a partially purified preparation. Hybridoma supernatants were screened for anti-rGRF activity by use of a pituitary culture assay system that can detect growth hormone-releasing factor in the femtomole range. Such highly sensitive in vitro techniques permit the use of picomole quantities of an antigen in partially purified preparations for the isolation of monoclonal antibodies, which can in turn be used in biological studies and in immunochemical procedures for large-scale purification and isolation of that antigen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Luben, R A -- Brazeau, P -- Bohlen, P -- Guillemin, R -- AD 09690-07/AD/ADAMHA HHS/ -- AM 18811-07/AM/NIADDK NIH HHS/ -- DE 00057/DE/NIDCR NIH HHS/ -- New York, N.Y. -- Science. 1982 Nov 26;218(4575):887-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6813967" target="_blank"〉PubMed〈/a〉

    Description: Teleocidin, which was isolated from mycelia of Streptomyces, is a potent tumor promoter in mouse skin. The catalytically hydrogenated compound dihydroteleocidin B markedly enhanced malignant cell transformation induced by 3-methylcholanthrene or ultraviolet radiation. Dihydroteleocidin B was at least 100 times more effective in enhancing transformation than 12-O-tetradecanoyl phorbol-13-acetate, the strongest promoter known until now, whereas both promoters showed equal capacities to induce early membrane effects and DNA synthesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hirakawa, T -- Kakunaga, T -- Fujiki, H -- Sugimura, T -- New York, N.Y. -- Science. 1982 Apr 30;216(4545):527-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6280280" target="_blank"〉PubMed〈/a〉

    A virally induced obesity syndrome in mice (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-04-02
    Description: An obesity syndrome was found in a number of mice infected as young adults with canine distemper virus, a morbillivirus antigenically related to measles. Body weights of obese animals 16 to 20 weeks after infection were comparable to those reported for genetically obese mice and for mice rendered obese by hypothalamic lesions. The total number of adipocytes in specific fat deposits was greater in obese animals than in their lean littermates. This hyperplasia was accompanied by moderate cell enlargement. Pancreatic islet tissue was also hypercellular in the obese mice. Brain tissue from the obese mice showed no overt pathology, and immunofluorescence staining for viral antigens was negative. There may be a selective, virus-induced disruption of critical brain catecholamine pathways.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lyons, M J -- Faust, I M -- Hemmes, R B -- Buskirk, D R -- Hirsch, J -- Zabriskie, J B -- AM 20508/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1982 Apr 2;216(4541):82-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7038878" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)

    Publication Date: 1982-04-16
    Description: A genetic map of 31 biochemical loci located on 17 feline syntenic (linkage) groups has been derived by somatic cell genetic analysis of cat-rodent hybrids. Most of these syntenic groups have been assigned to one of the 19 feline chromosomes. Comparative linkage analysis of the feline biochemical loci and homologous human loci revealed considerable conservation of linkage associations between the primates and the Felidae (order Carnivora). Many of these same linkage groups have not been conserved in the murine genome. The genetic and evolutionary implications of comparative mapping analysis among mammalian species are discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Brien, S J -- Nash, W G -- New York, N.Y. -- Science. 1982 Apr 16;216(4543):257-65.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7063884" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1982-01-15
    Description: Intraspecific human-human cell hybrids provide a stable model system with which to investigate the genetic control of transformed and tumorigenic phenotypes. Using this system it has been shown that these phenotypes are under separate genetic control. Furthermore, the tumorigenic phenotype can be complemented by fusion of different tumorigenic cells, resulting in nontumorigenic hybrids. This system also provides information on the control of differentiated function. Molecular cytogenetic techniques should reveal the nature of the chromosomal control of neoplastic transformation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stanbridge, E J -- Der, C J -- Doersen, C J -- Nishimi, R Y -- Peehl, D M -- Weissman, B E -- Wilkinson, J E -- CA09054/CA/NCI NIH HHS/ -- CA19401/CA/NCI NIH HHS/ -- GM07134/GM/NIGMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1982 Jan 15;215(4530):252-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7053574" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1982-04-30
    Description: Swiss mouse 3T3-C2 fibroblasts, grown to confluence in monolayer culture, are shown to fuse when exposed to electric fields. Exposure to five repetitive electric pulses of about 1 kilovolt per centimeter with a duration of 50 microseconds caused approximately 20 percent of the cells to become fused (multinucleate) when 1 millimolar magnesium was present in the medium. The effects of minimum thresholds of field strength, pulse duration, and number of pulses were determined. Cell disruption was observed when the electric field exceeded 2.0 kilovolts per centimeter or the pulse was of longer duration than 120 microseconds.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Teissie, J -- Knutson, V P -- Tsong, T Y -- Lane, M D -- AM14574/AM/NIADDK NIH HHS/ -- GM28795/GM/NIGMS NIH HHS/ -- RR5378/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1982 Apr 30;216(4545):537-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7071601" target="_blank"〉PubMed〈/a〉

    Description: Infanticide has been proposed to be a pathological response to overcrowding or other forms of environmental stress and thus a maladaptive behavior. However, in male house mice this behavior is predictable and is modulated by learning. Committing infanticide can increase a male's reproductive success and in some situations may therefore be an adaptive behavior.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉vom Saal, F S -- Howard, L S -- MH35079/MH/NIMH NIH HHS/ -- RR 07053/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1982 Mar 5;215(4537):1270-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7058349" target="_blank"〉PubMed〈/a〉

    Description: The transforming protein of Kirsten murine sarcoma virus (Ki-MuSV) is a virally encoded 21-kilodalton protein called p21 kis. The sequences encoding p21 kis were genetically localized to a 1.3-kilobase segment near the 5' end of the viral genome by assaying the capacity of a series of defined deletion mutants of molecularly cloned Ki-MuSV DNA to induce focal transformation of mouse cells. Nucleotide sequencing of a portion of this region has led to the identification of an open reading frame of 567 nucleotides coding for p21 kis protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsuchida, N -- Ryder, T -- Ohtsubo, E -- CA-22701/CA/NCI NIH HHS/ -- CA21124/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1982 Sep 3;217(4563):937-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6287573" target="_blank"〉PubMed〈/a〉
