    Description: 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〉

    Description: 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〉

    Description: 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〉

    Description: Raji cells, a human B lymphoblastoid cell line of Burkitt lymphoma origin, formed lupus inclusions when grown in a medium conditioned by the growth of Raji cells whose DNA thymidine residues had been unifilarly (single-strandedly) substituted with bromodeoxyuridine. Ultracentrifugation of this medium in excess of that required to remove Epstein-Barr virus and all other known mammalian viruses did not prevent the formation of the inclusions, and treatment of the conditioned medium with pronase destroyed the activity. These results demonstrate the presence of a protein that is secreted from bromodeoxyuridine-substituted Raji cells and is capable of inducing nonbromodeoxyuridine-substituted cells to form lupus inclusions. Interferon (100 units per milliliter) was found in the conditioned medium. Inclusions also formed in Raji cells grown in fresh medium supplemented with human leukocyte or fibroblast interferon (100 units per milliliter).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rich, S A -- New York, N.Y. -- Science. 1981 Aug 14;213(4509):772-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6166984" target="_blank"〉PubMed〈/a〉

    Description: The ability of murine tumor cells to metastasize spontaneously from subcutaneous sites is positively correlated with the total sialic acid content of the cells in culture, the degree to which the sialic acid is exposed on the tumor cell surface, and, most strongly, with the degree of sialylation of galactosyl and N-acetylgalactosaminyl residues in cell surface glycoconjugates.

    Description: Three cell lines were derived from a homosexual patient with probable acquired immunodeficiency syndrome and Burkitt's lymphoma. The cell lines produce an unusual strain of Epstein-Barr virus which will both transform cord blood lymphocytes and induce early antigens in Raji cells. Translocations between chromosomes 8 and 22 have occurred in all three lines, but the cells synthesize immunoglobulin M with light chains of the kappa type, in contrast to the usual concordance between a translocation involving chromosome 22 and lambda chain synthesis. Both kappa genes and one lambda gene are rearranged. These findings indicate either that translocation may occur as a separate event from immunoglobulin gene rearrangement or that the proposed hierarchical sequence of immunoglobulin gene rearrangements is not always adhered to. The data also imply that in cells containing a translocation between the long arm of chromosome 8 and a chromosome bearing an immunoglobulin gene, alteration of cellular myc expression may occur regardless of the immunoglobulin gene that is expressed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Magrath, I -- Erikson, J -- Whang-Peng, J -- Sieverts, H -- Armstrong, G -- Benjamin, D -- Triche, T -- Alabaster, O -- Croce, C M -- New York, N.Y. -- Science. 1983 Dec 9;222(4628):1094-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6316501" target="_blank"〉PubMed〈/a〉

This subunit of the insulin receptor was also labeled with [alpha-32P]8-azidoadenosine 5'-triphosphate, a photoaffinity label for adenosine triphosphate binding sites. The identity of the 95,000-dalton band was confirmed in both cases by precipitation with a monoclonal antibody to the insulin receptor.

    Description: Interleukin 2, a lymphokine that acts as a second signal of cellular immune response by way of its action as a T-cell growth factor, was morphologically identified by immunoperoxidase staining. With the use of a monoclonal antibody to interleukin 2 and several complex-forming antisera, the lymphokine was readily distinguished in cytocentrifuge preparations of peripheral blood leukocytes stimulated with a T-cell mitogen. When preparations of cloned interleukin 2 producer and responder cells were stained by the same procedures, discrete patterns of both responder and producer cell phenotypes were revealed. Interleukin 2 producer T cells exhibited a characteristic intense, ringlike cytoplasmic staining, whereas the responder cells (as exemplified by interleukin 2-dependent cell lines) exhibited a less intensive, spotlike membrane staining. In addition, intense membrane localization of interleukin 2, reminiscent of potential capping phenomena, could be observed in stained preparations of cloned responder cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Steinmann, G -- Conlon, P -- Hefeneider, S -- Gillis, S -- New York, N.Y. -- Science. 1983 Jun 10;220(4602):1188-90.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6344215" target="_blank"〉PubMed〈/a〉

    Description: Aplysiatoxin and debromoaplysiatoxin, which are isolated from the seaweed, Lyngbya gracilis, differ in their chemical structure only by the presence or absence of a bromine residue in the hydrophilic region. The function and the structure-activity relation of the hydrophilic region are not known. Aplysiatoxin increased malignant transformation, stimulated DNA synthesis, and inhibited the binding of phorbol-12,13-dibutyrate and epidermal growth factor to cell receptors. Debromoaplysiatoxin inhibited the binding of these two substances as strongly as aplysiatoxin but did not increase malignant transformation or stimulate DNA synthesis. These results indicate that a slight change in the chemical structure of the hydrophilic region of aplysiatoxin affects its abilities to increase cell transformation and stimulate DNA synthesis and that the abilities of the tumor promoters to inhibit the binding of phorbol-12,13-dibutyrate and epidermal growth factor are dissociable from their abilities to increase cell transformation and stimulate DNA synthesis under some circumstances.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shimomura, K -- Mullinix, M G -- Kakunaga, T -- Fujiki, H -- Sugimura, T -- New York, N.Y. -- Science. 1983 Dec 16;222(4629):1242-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6316505" target="_blank"〉PubMed〈/a〉

    Description: A biologically active rhodamine conjugate of thyrotropin binds at 4 degrees C to diffusely distributed membrane thyrotropin receptors which patch and become endocytosed into thyroid cells in a temperature-sensitive process. When the cells are first incubated with 8-bromo-cyclic adenosine monophosphate at 37 degrees C, the conjugate also binds to clustered receptors at 4 degrees C. Furthermore, 8-bromo-cyclic adenosine monophosphate reduces the amount of adenosine 3',5'-monophosphate (cyclic AMP) induced by thyrotropin. Hence, increased intracellular cyclic AMP induces receptor patching and reduces the concentration of cyclic AMP normally induced by thyrotropin. This suggests that cyclic AMP acts both as the second messenger of thyrotropin and also as the regulator of the level of thyrotropin receptors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Avivi, A -- Tramontano, D -- Ambesi-Impiombato, F S -- Schlessinger, J -- CA-25820/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Dec 11;214(4526):1237-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6272396" target="_blank"〉PubMed〈/a〉

    Description: Lactate dehydrogenase (LDH, E.C. 1.1.1.27) isozymes from three single-cell sources reacted differently with reduced nicotinamide adenine dinucleotide (NADH) purified to published chromatographic and spectrophotometric specifications and free of inhibitors of LDH, when compared with a commercial preparation of NADH. The activity of LDH-1, purified from rabbit erythrocytes, increased the most with inhibitor-free NADH; the next most stimulated were the LDH isozymes from a control hepatocyte line; but hardly responsive at all were the same isozymes from chemically transformed cells. Thus isozyme composition alone did not account for the range of responses to purified NADH. The commercial preparation of NADH used in these studies contains the Strandjord-Clayson inhibitors, the most potent group identified in NADH preparations relative to LDH activity. The results suggest that specific molecular differences in individual isozymes contribute to the differential response to the Strandjord-Clayson inhibitors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaplan, A E -- Weiss, E R -- Byrne, S T -- El-Torkey, N M -- Margolis, S A -- New York, N.Y. -- Science. 1981 May 1;212(4494):553-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7209551" target="_blank"〉PubMed〈/a〉

    Description: Inhibiting protein synthesis by incubating C6-2B rat astrocytoma cells with cycloheximide or emetine for periods up to 24 hours caused a progressive decrease in the accumulation of adenosine 3',5'-monophosphate (cyclic AMP) when the cells were challenged for 30 minutes with 100 microM forskolin. In contrast, cholera toxin-stimulated (6 nM, 3 hours) cyclic AMP accumulation was not diminished in cycloheximide-treated cells, and cyclic AMP was only minimally diminished in response to a 30-minute challenge with 10 microM (-)-isoproterenol. These experiments suggest the presence of a previously unrecognized cyclase component, which is essential for forskolin-stimulated cyclic AMP accumulation and has a shorter half-life than the beta-adrenergic receptor, the guanine nucleotide regulatory proteins, or the cyclase catalytic component.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brooker, G -- Pedone, C -- Barovsky, K -- HL 06330/HL/NHLBI NIH HHS/ -- HL 28940/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1983 Jun 10;220(4602):1169-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6190226" target="_blank"〉PubMed〈/a〉

    Description: The mouse neuroblastoma-rat glioma hybrid cell line NG108-15 was used to study the acute and chronic interaction of ethanol with intact neural cells. In the short term, ethanol inhibited opiate receptor binding, but after long-term exposure the cells exhibited an apparent adaptive increase in the number of opiate binding sites; this was reversible when ethanol was withdrawn. High concentrations of ethanol (200 mM) increased opiate binding after 18 to 24 hours, whereas lower concentrations (25 to 50 mM) produced similar changes after 2 weeks. This model system has potential for exploring the cellular and molecular mechanisms underlying ethanol intoxication, tolerance, and withdrawal.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Charness, M E -- Gordon, A S -- Diamond, I -- New York, N.Y. -- Science. 1983 Dec 16;222(4629):1246-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6316506" target="_blank"〉PubMed〈/a〉

    Description: The effect of hemin on the rate of synthesis and the level of globin messenger RNA's in the human erythroid cell line K562 was examined by means of cloned hybridization probes specific for each of the human embryonic, fetal, and adult globin genes. Hemin increases both the rate of transcription and the level of accumulation of zeta-, epsilon-, gamma-, and alpha-globin messenger RNA's by a factor of 3 to 5. Thus, hemin induction of globin gene expression in K562 cells is at the level of transcription.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Charnay, P -- Maniatis, T -- HL278989/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1983 Jun 17;220(4603):1281-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6574602" target="_blank"〉PubMed〈/a〉

    Description: Human T-cell leukemia virus (HTLV), American PL isolate, was transmitted by cocultivation and by cell-free filtrates to a nonlymphoid human osteogenic sarcoma (HOS) cell line, designated HOS/PL, but not to nine other lines bearing receptors for HTLV. HOS and HOS/PL cells are not dependent on interleukin-2 and do not express interleukin-2 receptors that are recognized by anti-Tac monoclonal antibody. HTLV released by the Japanese MT2 cell line was also transmitted to HOS cells. The infected HOS cells release substantial titers of progeny HTLV which is antigenically indistinguishable from parental virus and is able to transform T cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clapham, P -- Nagy, K -- Cheingsong-Popov, R -- Exley, M -- Weiss, R A -- New York, N.Y. -- Science. 1983 Dec 9;222(4628):1125-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6316502" target="_blank"〉PubMed〈/a〉

    Description: After transport in the blood and implantation in the microcirculation, metastatic tumor cells must invade the vascular endothelium and underlying basal lamina. Mouse B16 melanoma sublines were used to determine the relation between metastatic properties and the ability of the sublines to degrade enzymatically the sulfated glycosaminoglycans present in the extracellular matrix of cultured vascular endothelial cells. Highly invasive and metastatic B16 sublines degraded matrix glycosaminoglycans faster than did sublines of lower metastatic potential. The main products of this matrix degradation were heparan sulfate fragments. Intact B16 cells (or their cell-free homogenates) with a high potential for lung colonization degraded purified heparan sulfate from bovine lung at higher rates than did B16 cells with a poor potential for lung colonization. Analysis of the degradation fragments indicated that B16 cells have a heparan sulfate endoglycosidase. Thus the abilities of B16 melanoma cells to extravasate and successfully colonize the lung may be related to their capacities to degrade heparan sulfate in the walls of pulmonary blood vessels.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nakajima, M -- Irimura, T -- Di Ferrante, D -- Di Ferrante, N -- Nicolson, G L -- R01-AM-26482/AM/NIADDK NIH HHS/ -- R01-CA-28867/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1983 May 6;220(4597):611-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6220468" target="_blank"〉PubMed〈/a〉

The antibody demonstrated a strict steric specificity since it did not react with globoisotriaosylceramide [Gal alpha (1 leads to 3)-Gal beta (1 leads to 4)-Glc beta (1 leads to 1)-ceramide], the positional isomer of the antigen associated with the Burkitt lymphoma.

    Description: Cells of the murine plasmacytoid line MOPC-315 synthesize two distinct immunoglobulin light chains: a normal lambda II protein, which is incorporated into secretory and surface-bound immunoglobulin, and a truncated, nonfunctional lambda I protein found only in the cytoplasm. Idiotype-specific suppressor T lymphocytes selectively inhibit the expression of both lambda II- and lambda I-specific messenger RNA by MOPC-315 cells. This finding demonstrates that phenotypically excluded light chain genes can be subject to immunoregulatory control and suggests that the expression of divergent lambda isotypes may be coordinately regulated in immunoglobulin-secreting cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parslow, T G -- Milburn, G L -- Lynch, R G -- Granner, D K -- AM25295/AM/NIADDK NIH HHS/ -- CA28848/CA/NCI NIH HHS/ -- CA32275/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1983 Jun 24;220(4604):1389-91.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6222474" target="_blank"〉PubMed〈/a〉

    Description: Steroid hormones, when complexed to their receptors, recognize and bind specific DNA sequences and subsequently induce increased levels of transcription. The mechanisms of steroid hormone action were analyzed by constructing chimeric DNA molecules from portions of mouse mammary tumor virus envelope and long terminal repeat (LTR) regions ligated to the thymidine kinase (tk) gene of herpes simplex virus. This construction allowed the tk gene to be expressed in a hormone-responsive fashion upon transfection into Ltk- cells. Comparison of transcription data with in vitro binding data showed that hormone-responsive transcription can be directly correlated to the presence of steroid hormone receptor binding sites on the DNA. There are at least two such receptor binding sites in the LTR region, one between -202 and -137 and another between -137 and -50 base pairs from the RNA cap site, as well as a site near the 5' end of the envelope region. These results strengthen the hypothesis that steroid-receptor complexes regulate genes primarily by binding to DNA sites near the promoter region and thereby modulate transcription.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pfahl, M -- McGinnis, D -- Hendricks, M -- Groner, B -- Hynes, N E -- New York, N.Y. -- Science. 1983 Dec 23;222(4630):1341-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6318311" target="_blank"〉PubMed〈/a〉

    Description: Twenty micromolar hemin causes no change in the rate of division of K562 cells but results in accumulation of 11 to 14 picograms of embryonic and fetal hemoglobins per cell. This effect is reversible, and hemoglobin induction in response to hemin, and loss of hemoglobin upon removal of hemin, can be cyclically repeated. The cells can be indefinitely subcultured in the presence of the inducer. Thus, the control of hemoglobin levels in K562 cells does not depend on irreversible differentiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dean, A -- Erard, F -- Schneider, A P -- Schechter, A N -- AM 00103/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1981 Apr 24;212(4493):459-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6163216" target="_blank"〉PubMed〈/a〉

    Description: A point mutation alters the 12th amino acid of the c-Ha-ras oncogene product p21 in a human bladder cancer cell line. This is, at present, the only mutation known to result in a human transforming gene. This mutation may therefore represent a possible target for mutagenesis leading to carcinogenesis in humans. By means of restriction enzyme analysis, 29 human cancers, including 20 primary tumor tissues, derived from organs commonly exposed to environmental carcinogens, were tested for the presence of this mutation. None of ten primary bladder carcinomas exhibited the mutation; nor did nine colon carcinomas or ten carcinomas of the lung. Thus the point mutation affecting the 12th amino acid of the c-Ha-ras gene product, while a valuable model for carcinogenesis, does not appear to play a role in the development of most human epithelial cancers of the bladder, colon, or lung.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feinberg, A P -- Vogelstein, B -- Droller, M J -- Baylin, S B -- Nelkin, B D -- 09071/PHS HHS/ -- 24592/PHS HHS/ -- 31053/PHS HHS/ -- etc. -- New York, N.Y. -- Science. 1983 Jun 10;220(4602):1175-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6304875" target="_blank"〉PubMed〈/a〉
