    Beschreibung: Sexual dimorphism in selected extragenital tissues is described with emphasis on the molecular basis of the differences. Testosterone rather than 5 alpha-dihydrotestosterone appears to be the major intracellular androgen in organs other than skin and reproductive tract, but other steroid metabolites and their receptors are required to produce the diverse tissue differences observed in males and females. There is also evidence that multiple hormones from several endocrine glands are required to act in concert with androgens to produce and maintain their effects. Although many of the consequences of sexual dimorphism, such as body size and strength, have been evident for centuries, other differences between males and females such as disease incidence, response to drugs and toxins, and the metabolism and assimilation of dietary constituents have only recently been discovered.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bardin, C W -- Catterall, J F -- HD-13541/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1981 Mar 20;211(4488):1285-94.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7010603" target="_blank"〉PubMed〈/a〉

    Beschreibung: Voltage-clamp recordings from mouse spinal neurons grown in culture were used to study the membrane current fluctuations induced by 12 substances structurally similar to gamma-aminobutyric acid (GABA). Fluctuation analysis provided estimates of the electrical properties of the elementary events underlying these responses. Estimates of the mean conductance of channels activated by all of the substances except glycine did not differ significantly from that estimated for GABA, whereas mean durations of agonist-activated channels all differed significantly from that found for GABA. The results indicate that all of the substances tested except glycine activate channels of similar conductance but of different durations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barker, J L -- Mathers, D A -- New York, N.Y. -- Science. 1981 Apr 17;212(4492):358-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6259733" target="_blank"〉PubMed〈/a〉

    Beschreibung: The synthetic peptide NH2-Tyr-Pro-Phe-Pro-CONH2 (morphiceptin), which is the amide of a fragment of the milk protein beta-casein, has morphinelike activities and is highly specific for morphine (mu) receptors but not for enkephalin (delta) receptors. It is as active as morphine in the guinea pig ileum but much less active in the mouse and rat vas deferens. The discovery of this specific morphine receptor ligand substantiates the hypothesis of multiple opiate receptors. The ligand, which may be of physiological significance since a very similar, or identical, activity can be detected in enzymatic digests of beta-casein, may prove useful for further investigation of the functions of opiate receptor subtypes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chang, K J -- Lillian, A -- Hazum, E -- Cuatrecasas, P -- Chang, J K -- New York, N.Y. -- Science. 1981 Apr 3;212(4490):75-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6259732" target="_blank"〉PubMed〈/a〉

    Beschreibung: The systemic comparison of every newly determined amino acid sequence with all other known sequences may allow a complete reconstruction of the evolutionary events leading to contemporary proteins. But sometimes the surviving similarities are so vague that even computer-based sequence comparisons procedures are unable to validate relationships. In other cases similar sequences may appear in totally alien proteins as a result of mere chance or, occasionally, by the convergent evolution of sequences with special properties.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Doolittle, R F -- New York, N.Y. -- Science. 1981 Oct 9;214(4517):149-59.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7280687" target="_blank"〉PubMed〈/a〉

    Beschreibung: Cells of the homogeneous hybrid line neuroblastoma x glioma (NG108-15) have many neuronal properties. Immunocytochemical tests show that they contain both immunoreactive renin and angiotensin; direct radioimmunoassays show that they are positive for renin, angiotensin I, and angiotensin II; enzymatic assays show that they contain angiotensinogen and converting enzyme as well. The renin appears to be present in an enzymatically inactive form that can be activated by trypsin and then blocked by antiserum to purified mouse submaxillary renin. Renin concentration and activity are increased by enhancing cellular differentiation with dibutyryl cyclic adenosine monophosphate or by serum withdrawal. These findings demonstrate a complete renin-angiotensin system within these neuron-like cells, and suggest that activation of intracellular renin could generate angiotensin II.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fishman, M C -- Zimmerman, E A -- Slater, E E -- HL-21247/HL/NHLBI NIH HHS/ -- HL-24105/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1981 Nov 20;214(4523):921-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6272392" target="_blank"〉PubMed〈/a〉

    Beschreibung: Human malignant cancer tumors grafted into nude mice produce tumors containing both human cancer cells and the host's stromal cells. After short-term propagation of these tumors in vitro, the murine mesenchymal cells appear transformed and are tumorigenic in nude mice. However, established human cancer cell lines fail to similarly after adjacent murine stromal cells when used to produce tumors in nude mice. These experiments suggest that cancer cells may recruit normal cells to become malignant, qualifying the view of the clonal (unicellular) origin of cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goldenberg, D M -- Pavia, R A -- 1R01 CA17198/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Apr 3;212(4490):65-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7209521" target="_blank"〉PubMed〈/a〉

    Beschreibung: Voltage clamp studies of macrophages from cultures of mouse spleen macrophages produced N-shaped steady-state current-voltage curves containing a region of negative slope resistance. Some macrophages exhibit two stable states of membrane potential, having current-voltage relationships that cross the voltage axis at three points. Outward currents that turn on at voltages of +15 millivolts or greater were noted in several cells. The addition of barium chloride to the bathing medium abolished the negative slope resistance and reduced the inward currents in response to hyperpolarizing voltage steps. These data provide direct evidence that macrophages exhibit at least tow different voltage-dependent conductances and demonstrate that voltage clamp techniques can be useful in studying the membrane properties of leukocytes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gallin, E K -- New York, N.Y. -- Science. 1981 Oct 23;214(4519):458-60.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7291986" target="_blank"〉PubMed〈/a〉

    Beschreibung: Two divalent cation ionophores, A23187 and Ionomycin, which are selective for calcium, stimulated the resorption of fetal rat long bones in organ culture at 0.1 to 1 micromolar but not at higher concentrations. Both agents inhibited DNA synthesis at concentrations that stimulated resorption. These results might explain the differences in ionophore effects on bone previously reported, and they imply that cell replication is not required for osteoclast formation in fetal rat long bone cultures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lorenzo, J A -- Raisz, L G -- AM 07290/AM/NIADDK NIH HHS/ -- AM 18063/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1981 Jun 5;212(4499):1157-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6785885" target="_blank"〉PubMed〈/a〉

    Beschreibung: A loss in the number of functional, sodium ion-dependent, high-affinity choline transport sites was observed in the cortex and hippocampus of mice given an intracerebroventricular injection of 65 nanomoles of AF64A (ethylcholine mustard aziridinium ion) 3 days earlier. Such an effect was not observed in the striatum. This effect of AF64A represents a long-term neurochemical deficit at cholinergic nerve terminals in some brain regions which can lead to a persistent deficiency in central cholinergic transmission. The AF64A-treated animal may thus be a model for certain psychiatric or neurological disorders that appear to involve central cholinergic hypofunction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mantione, C R -- Fisher, A -- Hanin, I -- MH 26320/MH/NIMH NIH HHS/ -- MH/AG 34893/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1981 Jul 31;213(4507):579-80.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6894649" target="_blank"〉PubMed〈/a〉

    Beschreibung: Analogs of adenosine 3',5'-monophosphate (cyclic AMP) inhibit the growth of cultured cell lines. The effects of 8-bromo- and N6-butyryl-substituted analogs of cyclic and noncyclic AMP on six cell lines were examined and were equally inhibitory. Variant cell lines with altered cyclic AMP-dependent protein kinase were more resistant to both cyclic and noncyclic nucleotides. We conclude that growth inhibition by analogs of cyclic AMP (i) does not require a 3',5' phosphodiester bond and (ii) may be mediated by a pathway involving endogenous cyclic AMP.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martin, T F -- Kowalchyk, J A -- AM 25861/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1981 Sep 4;213(4512):1120-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6267695" target="_blank"〉PubMed〈/a〉

    Beschreibung: Mice fed a purified diet low in copper display anemia, hypoceruloplasminemia, depressed concentrations of liver copper, and elevated concentrations of liver iron. An impaired humoral-mediated immune response (decreased numbers of antibody-producing cells) is observed in mice with severe as well as marginal copper deficiency. The magnitude of this impairment is highly correlated with the degree of functional copper deficiency (hypoceruloplasminemia).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Prohaska, J R -- Lukasewycz, O A -- New York, N.Y. -- Science. 1981 Jul 31;213(4507):559-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7244654" target="_blank"〉PubMed〈/a〉

    Beschreibung: Unmyelinated mouse cerebellar cerebellar cultures in which oligodendrocyte differentiation had been suppressed by exposure to cytosine arabinoside developed axonal myelin after superimposition of kainic acid-treated cerebellar explants devoid of myelin-receptive axons.

    Beschreibung: The aorta of the octopus, Octopus dofleini, is a highly distensible, elastic tube. The circumferential elastic modulus increases with inflation in the physiological range from abut 10(4) to 10(5) newtons per square meter. Rubber-like fibers have been isolated, apparently for the first time, from the aorta of an invertebrate. These fibers have an elastic modulus, like elastin, of about 4 x 10(5) newtons per square meter and are present in sufficient quantity to account for the elastic properties of the intact vessel under physiological conditions. Thus the circulatory system of an invertebrate animal provides an "elastic reservoir" (much like that of the vertebrate system), which increases the efficiency of the circulation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shadwick, R E -- Gosline, J M -- New York, N.Y. -- Science. 1981 Aug 14;213(4509):759-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7256277" target="_blank"〉PubMed〈/a〉

    Beschreibung: The low activity of liver neuraminidase that is characteristic of mouse strain SM/J is inherited as a single gene on chromosome 17, near the major histocompatibility complex. This gene, neuraminidase-1 (Neu-1), is represented by the low activity allele Neu-1s in SM/J and the high activity allele Neu-1b in C57BL/6J and most other strains. Previously described variations in the posttranslational processing of acid phosphatase, alpha-mannosidase, arylsulfatase-B, and alpha-glucosidase are attributed to pleiotropic effects of this gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Womack, J E -- Yan, D L -- Potier, M -- New York, N.Y. -- Science. 1981 Apr 3;212(4490):63-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7209520" target="_blank"〉PubMed〈/a〉

Each onc gene counterpart has a single genetic locus, which probably contains non-onc intervening sequences. The human DNA sequences may represent genes important to cell growth or cell differentiation, or both. Their identification and isolation may allow elucidation of their role in these processes and in neoplasias.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wong-Staal, F -- Dalla-Favera, R -- Franchini, G -- Gelmann, E P -- Gallo, R C -- New York, N.Y. -- Science. 1981 Jul 10;213(4504):226-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6264598" target="_blank"〉PubMed〈/a〉

    Beschreibung: Growth of mouse lymphoma L5178Y, which contains large quantitites of the gangliotriosylceramide (GgOs3Cer), in DBA/2 mice was suppressed by passive immunization with monoclonal immunoglobulin G3 antibodies to GgOS3Cer, but not by immunoglobulin M antibodies with or without added complement. Most groups of mice treated with monoclonal immunoglobulin G3 antibodies did not develop tumors, but the tumor that appeared in a treated animal had a much lower amount of the GgOS3Cer than the cells used for inoculation. Thus, passive immunization either prevented growth of the lymphoma or caused selection of a variant with a lower quantity of the antigen GgOS3Cer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Young, W W Jr -- Hakomori, S I -- CA27746/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Jan 30;211(4481):487-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7455688" target="_blank"〉PubMed〈/a〉

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 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〉

    Beschreibung: 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〉

    Beschreibung: 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. The alpha-substituted-gama-butyrolactones represent a new class of anticonvulsant drug with experimental and clinical potential.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Klunk, W E -- McKeon, A -- Covey, D F -- Ferrendelli, J A -- GM-07200/GM/NIGMS NIH HHS/ -- GM-24483/GM/NIGMS NIH HHS/ -- NS-14834/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1982 Sep 10;217(4564):1040-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6810462" target="_blank"〉PubMed〈/a〉

    Beschreibung: 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〉

    Beschreibung: Urotensin I, purified from extracts of the urophysis of a teleost fish (Catostomus commersoni), exhibits potent hypotensive activity (mammals and birds) and corticotropin-releasing activity (both fish and mammals). The primary structure of this 41-residue peptide was determined to be H-Asn-Asp-Asp-Pro-Pro-Ile-Ser-Ile-Asp-Leu-Thr-Phe-His-Leu-Leu-Arg-Asn-Met-Ile-Glu - Met-Ala-Arg-Ile-Glu-Asn-Glu-Arg-Glu-Gln-Ala-Gly-Leu-Asn-Arg-Lys-Tyr-Leu-Asp-Glu -Val-NH2. Extraction with 0.1N HCl at 100 degrees C cleaves the amino-terminal tripeptide, yeilding a fully active analog, urotensin I(4-41). The amino acid sequence was confirmed by measuring the biological activity of synthetic urotensin I(4-41). Urotensin I exhibits a striking sequence homology with ovine corticotropin-releasing factor and with frog sauvagine. These three peptides exhibit similar activities in biological test systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lederis, K -- Letter, A -- McMaster, D -- Moore, G -- Schlesinger, D -- New York, N.Y. -- Science. 1982 Oct 8;218(4568):162-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6981844" target="_blank"〉PubMed〈/a〉

    Beschreibung: 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〉

    Beschreibung: 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〉

    Beschreibung: 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〉

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〉

    Beschreibung: 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〉

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.

    Beschreibung: 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〉

    Beschreibung: Certain toxic lectins, including ricin, are retrogradely transported along neuronal processes to the cell body where they inactivate ribosomes, resulting in neuronal death.

    Beschreibung: 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〉

    Beschreibung: 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〉

    Beschreibung: 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〉

    Beschreibung: Mice were injected daily, for up to 10 weeks, with purified monoclonal immunoglobulin G from patients with myelomatous polyneuropathy or benign gammopathy. The animals developed a demyelinating polyneuropathy with slowed nerve conduction velocities. The putative antinerve factor may be an antibody since injection of Fab fragments from the monoclonal immunoglobulin G produced a similar demyelination. This provides evidence of a circulating factor in the serum of myeloma patients with polyneuropathy that reproduces typical features of the human disease on passive transfer. This disorder is thus distinguished from other neuropathies that occur as remote effects of malignant disease but have no identified pathogenic factors associated with them.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Besinger, U A -- Toyka, K V -- Anzil, A P -- Fateh-Mognadam, A -- Rouscher, R -- Heininger, K -- New York, N.Y. -- Science. 1981 Aug 28;213(4511):1027-30.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7268405" target="_blank"〉PubMed〈/a〉

    Beschreibung: Oral administration of delta 9-tetrahydrocannabinol had a biphasic effect on plasma testosterone concentrations in male mice, causing rapid sustained increases at low doses and subsequent decreases at higher doses. In hypophysectomized and intact mice receiving gonadotropins (human chorionic gonadotropin), treatment with delta 9-tetrahydrocannabinol maintained higher plasma testosterone concentrations.

The conjugate was 375- to 750-fold more inhibitory to murine T lymphoma S49.1 cells than the unconjugated derivative. At 0.7 X 10(-7) to 1.5 X 10(-7) M and at 4 X 10(-7) M amanitin equivalents, the conjugate inhibited protein synthesis in S49.1 cells by 50 percent and 80 to 96 percent, respectively. At these concentrations, mutant Thy l-deficient S49 cells and other murine lymphoma lacking Thy l altogether or carrying Thy 1.1 antigens were unaffected.

Occasionally, polygonal somas positive for substance P were found in the ganglion cell layer. Approximately 75 percent of the cell bodies positive for substance P and 65 percent of the radioimmunoassayable substance P were found in the superior half of the frog retina. On the basis of high-performance liquid chromatography, the immunoreactive substance P in the neural retina of the rat, monkey, or chick is similar to synthetic substance P, whereas this is not true of the immunoreactive substance P in the bullfrog or carp retina.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eskay, R L -- Furness, J F -- Long, R T -- New York, N.Y. -- Science. 1981 May 29;212(4498):1049-50.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6165081" target="_blank"〉PubMed〈/a〉

    Beschreibung: When bound to cell surfaces, certain lectins such as concanavalin A induce a drop in the average diffusion coefficients (D) of a number of cell surface molecules. To find whether such anchorage modulation occurs naturally, D of surface antigens on different cell and tissue types were measured by fluorescence photobleaching recovery. Values for cells of the same tissue origin under different conditions of growth and association - in tissues, in small aggregates, and as isolated cells - varied by less than twofold when polyspecific monovalent antibodies to cell surface antigens were used, a range much less than the sixfold decrease in D observed after lectin-induced anchorage modulation. Thus, if reversible modulation of the diffusion rate is used naturally as a means of cell signaling, it must involve only a few kinds of surface receptors not detected by the antibodies used in this study. In certain tissues, however, a significant proportion of cells showed no apparent receptor mobility. This "all or none" modulation of lateral diffusion may reflect relatively long-lasting alterations in the states of a single cell type or differentiation among the cells of the particular tissue.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gall, W E -- Edelman, G M -- AI-09273/AI/NIAID NIH HHS/ -- AI-11378/AI/NIAID NIH HHS/ -- AM-04256/AM/NIADDK NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1981 Aug 21;213(4510):903-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7196087" target="_blank"〉PubMed〈/a〉

The incorporation of [2H4]choline into acetylcholine declined 60 and 73 percent in 10- and 30-month-old mice, respectively. Deficits in the cholinergic system may contribute to brain dysfunctions that complicate senescence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gibson, G E -- Peterson, C -- Jenden, D J -- MH17691/MH/NIMH NIH HHS/ -- MS15649/PHS HHS/ -- NS16997/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1981 Aug 7;213(4508):674-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7256270" target="_blank"〉PubMed〈/a〉

    Beschreibung: Sex differentiation is the result of the translation of genetic sex into gonadal sex. Without recognizable masculinizing signals the embryonic gonad will undergo ovarian differentiation. The main determinant of gonadal differentiation appears to be the presence or absence of a cell surface antigen, called H-Y antigen. The regulation of H-Y antigen expression is complex and involves the interaction between regulatory sites on the Y chromosome, the X chromosome, and possibly the autosomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Haseltine, F P -- Ohno, S -- 5R01 HD 12289-02/HD/NICHD NIH HHS/ -- R0I AD 00042/AD/ADAMHA HHS/ -- New York, N.Y. -- Science. 1981 Mar 20;211(4488):1272-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7010601" target="_blank"〉PubMed〈/a〉

    Beschreibung: Malaria parasites isolated from mouse erythrocytes are lysed by ferriprotoporphyrin IX chloride (hemin) or by a chloroquine-hemin complex in amounts that could be produced by release of less than 0.1 percent of the heme in erythrocytic hemoglobin. This effect of hemin may explain the protection against malaria provided by thalassemia and other conditions causing intracellular denaturation of hemoglobin. The toxicity of the chloroquine-hemin complex may explain the selective antimalarial action of chloroquine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Orjih, A U -- Banyal, H S -- Chevli, R -- Fitch, C D -- New York, N.Y. -- Science. 1981 Nov 6;214(4521):667-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7027441" target="_blank"〉PubMed〈/a〉

    Beschreibung: The gene for prolactin has been located on chromosome 6 in humans. DNA fragments of 4.8 and 4.0 kilobases containing prolactin gene sequences were identified in human genomic DNA, whereas DNA fragments of 7.4, 3.6, and 3.3 kilobases containing prolactin gene sequences were found in mouse cells. In somatic cell hybrids of human and mouse cells the 7.4-, 3.6-, and 3.3-kilobase mouse fragments were always present, whereas the 4.8- and 4.0-kilobase human fragments were only present when human chromosome 6 was also present. We conclude that the prolactin gene resides on chromosome 6, a different location from those of the genes for the related hormones chorionic somatomammotropin and growth hormone.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Owerbach, D -- Rutter, W J -- Cooke, N E -- Martial, J A -- Shows, T B -- AM 21344/AM/NIADDK NIH HHS/ -- GM 20454/GM/NIGMS NIH HHS/ -- HD 05196/HD/NICHD NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1981 May 15;212(4496):815-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7221563" target="_blank"〉PubMed〈/a〉

    Beschreibung: Methionine enkephalin release was evoked by depolarization of slices from rat striatum with potassium. In the presence of 0.1 microM thiorphan [(N(R,S)-3-mercapto-2-benzylpropionyl)glycine], a potent inhibitor of enkephalin dipeptidyl carboxypeptidase (enkephalinase), the recovery of the pentapeptide in the incubation medium was increased by about 100 percent. A similar effect was observed with the dipeptide phenylalanylalanine, a selective although less potent enkephalinase inhibitor. Inhibition of other known enkephalin-hydrolyzing enzymes--aminopeptidase by 0.1 mM puromycin or angiotensin-converting enzyme by 1 microM captopril--did not significantly enhance the recovery of released methionine enkephalin. These data indicate that enkephalinase is critically involved in the inactivation of the endogenous opioid peptide released from striatal neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Patey, G -- De La Baume, S -- Schwartz, J C -- Gros, C -- Roques, B -- Fournie-Zaluski, M C -- Soroca-Lucas, E -- New York, N.Y. -- Science. 1981 Jun 5;212(4499):1153-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7015510" target="_blank"〉PubMed〈/a〉

    Beschreibung: Emotional, psychosocial, or anxiety-stimulated stress produces increased plasma concentrations of adrenal corticoids and other hormones though well-known neuroendocrine pathways. A direct consequence of these increased corticoid concentrations is injury to elements of the immunological apparatus, which may leve the subject vulnerable to the action of latent oncogenic viruses, newly transformed cancer cells, or other incipient pathological processes that are normally held in check by an intact immunological apparatus. This article describes studies that examine the adverse effects of increased plasma concentrations of adrenal corticoids on the thymus and thymus-dependent T cells, inasmuch as these elements constitute a major defense system against various neoplastic processes and other pathologies. The studies demonstrate that anxiety-stress can be quantitatively induced and the consequences measured through specific biochemical and cellular parameters, providing that authentic quiescent baselines of these conditions are obtained in the experimental animals by the use of low-stress protective housing and handling techniques.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Riley, V -- CA 12188/CA/NCI NIH HHS/ -- CA 16308/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Jun 5;212(4499):1100-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7233204" target="_blank"〉PubMed〈/a〉

    Beschreibung: 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.

The amount of toxin bound to the receptors was determined and the kinetics of dissociation of the receptor-toxin complex was followed. 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.

    Beschreibung: 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〉

    Beschreibung: 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〉

    Beschreibung: 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〉

    Beschreibung: 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〉

    Beschreibung: 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〉

    Beschreibung: 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〉

    Beschreibung: 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〉
