    Description: Papillomaviruses (PV) contain several conserved genes that may encode nonstructural proteins; however, none of these predicted gene products have been identified. Papillomavirus E6 genes are retained and expressed as RNA in PV-associated human and animal carcinomas and cell lines. This suggests that the E6 gene product may be important in the maintenance of the malignant phenotype. The E6 open reading frame of the bovine papillomavirus (BPV) genome has been identified as one of two BPV genes that can independently transform mouse cells in vitro. A polypeptide encoded by this region of BPV was produced in a bacterial expression vector and used to raise antisera. The antisera specifically immunoprecipitated the predicted 15.5-kilodalton BPV E6 protein from cells transformed by the E6 gene. The E6 protein was identified in both the nuclear and membrane fractions of these transformed cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Androphy, E J -- Schiller, J T -- Lowy, D R -- 5-F32-CA-07237/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1985 Oct 25;230(4724):442-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2996134" target="_blank"〉PubMed〈/a〉

    Description: In a study of recombinant proteins that might be useful in developing a vaccine against malaria, synthetic peptides from the circumsporozoite (CS) protein of Plasmodium falciparum were found to be immunogenic for mice and rabbits. Antibody to peptides from the repeating region of the CS protein recognized native CS protein and blocked sporozoite invasion of human hepatoma cells in vitro. Antibodies to peptides from regions I and II had no biologic activity, although antibody to region I recognized processed CS protein by Western blot analysis. These data support the feasibility of developing a vaccine against the sporozoite stage of the malaria parasite by using synthetic peptides of the repeating region of the CS protein conjugated to a carrier protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ballou, W R -- Rothbard, J -- Wirtz, R A -- Gordon, D M -- Williams, J S -- Gore, R W -- Schneider, I -- Hollingdale, M R -- Beaudoin, R L -- Maloy, W L -- New York, N.Y. -- Science. 1985 May 24;228(4702):996-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2988126" target="_blank"〉PubMed〈/a〉

    Description: The T-cell receptor beta-chain gene has a nuclease hypersensitive site in several kinds of T cells, which does not appear in B cells expressing immunoglobulins. Conversely, the kappa immunoglobulin gene shows a known hypersensitive site at its enhancer element in B cells, as expected, but this site is absent in T cells. As is the case with immunoglobulin genes, the T-cell receptor site lies within the gene, in the intron separating joining and constant region segments. These nuclease hypersensitive DNA configurations in the introns of active T-cell receptor and immunoglobulin genes may arise from control elements that share ancestry but have diverged to the extent that each normally acts only in lymphoid cells which use the proximal gene product.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bier, E -- Hashimoto, Y -- Greene, M I -- Maxam, A M -- AI 19901/AI/NIAID NIH HHS/ -- CA 22427/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1985 Aug 9;229(4713):528-34.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3927483" target="_blank"〉PubMed〈/a〉

    Description: Nonhomologous DNA recombination is frequently observed in somatic cells upon the introduction of DNA into cells or in chromosomal events involving sequences already stably carried by the genome. In this report, the DNA sequences at the crossover points for excision of SV40 from chromosomes were shown to be associated with eukaryotic topoisomerase I cleavage sites in vitro. The precise location of the cleavage sites relative to the crossover points has suggested a general model for nonhomologous recombination mediated by topoisomerase I.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bullock, P -- Champoux, J J -- Botchan, M -- CA 30490/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1985 Nov 22;230(4728):954-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2997924" target="_blank"〉PubMed〈/a〉

    Description: Both elemental distribution and ion transport in cultured cells have been imaged by ion microscopy. Morphological and chemical information was obtained with a spatial resolution of approximately 0.5 micron for sodium, potassium, calcium, and magnesium in freeze-fixed, cryofractured, and freeze-dried normal rat kidney cells and Chinese hamster ovary cells. Ion transport was successfully demonstrated by imaging Na+-K+ fluxes after the inhibition of Na+- and K+ -dependent adenosine triphosphatase with ouabain. This method allows measurements of elemental (isotopic) distribution to be related to cell morphology, thereby providing the means for studying ion distribution and ion transport under different physiological, pathological, and toxicological conditions in cell culture systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chandra, S -- Morrison, G H -- R01GM24314/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1985 Jun 28;228(4707):1543-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2990033" target="_blank"〉PubMed〈/a〉

    Description: The reported incidence of acquired immune deficiency syndrome (AIDS) continues to increase in countries throughout the world. On the basis of a polynomial model for extrapolation, the cumulative number of cases diagnosed and reported since 1981 in the United States is expected to double during the next year with over 12,000 additional cases projected to be diagnosed by July 1986. The annual incidence rates for single (never-married) men in Manhattan and San Francisco, intravenous drug users in New York City and New Jersey, and persons with hemophilia A ranged from 261 to 350 per 100,000 population during 1984. For single men aged 25 to 44 years in Manhattan and San Francisco, AIDS was the leading cause of premature mortality in 1984 as measured by years of potential life lost. Infection with HTLV-III/LAV is considerably more common than reported AIDS in high-risk populations and can persist at least for several years, so the presence of specific antibody should be considered presumptive evidence of current infection. The screening of donated blood and plasma for antibody to HTLV-III/LAV and use of safer clotting factor concentrates should greatly reduce HTLV-III/LAV transmission through blood and blood products. Most HTLV-III/LAV infections occur through sexual transmission, use of contaminated needles, and as a result of infected mothers passing the virus to newborns. Continued research commitment is needed to develop an HTLV-III/LAV vaccine and therapy for this infection. In the interim, widespread community efforts are needed to minimize transmission.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Curran, J W -- Morgan, W M -- Hardy, A M -- Jaffe, H W -- Darrow, W W -- Dowdle, W R -- New York, N.Y. -- Science. 1985 Sep 27;229(4720):1352-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2994217" target="_blank"〉PubMed〈/a〉

    Description: Fibrinogen fragment D, which is heterogeneous, has several important biological functions. Human fibrinogen fragments D94 (molecular weight, 94,000), D78 (78,000), and E (52,000) were purified. Fragments D78 and D94 but not purified fibrinogen or fragment E specifically caused disorganization of bovine aortic endothelial cells cultured as monolayers. Within 2 hours of exposure to pathophysiological concentrations of fragment D, the confluent endothelial cells retracted from each other and projected pseudopodia. These disturbed cells subsequently became rounded and detached from the substrate. The actin present in stress fibers in stationary monolayer cells was diffusely redistributed in cells with fragment D-induced alterations in morphology. This effect was not observed in monolayers of kidney epithelial cells. The results demonstrate a specific effect of fibrinogen fragment D on the disorganization of cultured vascular endothelial cell monolayers and suggest that fragment D plays a role in the pathogenesis of syndromes with vascular endothelial damage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dang, C V -- Bell, W R -- Kaiser, D -- Wong, A -- New York, N.Y. -- Science. 1985 Mar 22;227(4693):1487-90.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/4038818" target="_blank"〉PubMed〈/a〉

    Description: The retroviral transmembrane envelope protein p15E is immunosuppressive in that it inhibits immune responses of lymphocytes, monocytes, and macrophages. A region of p15E has been conserved among murine and feline retroviruses; a homologous region is also found in the transmembrane envelope proteins of the human retroviruses HTLV-I and HTLV-II and in a putative envelope protein encoded by an endogenous C-type human retroviral DNA. A peptide (CKS-17) was synthesized to correspond to this region of homology and was examined for its effects on lymphocyte proliferation. CKS-17 inhibited the proliferation of an interleukin-2-dependent murine cytotoxic T-cell line as well as alloantigen-stimulated proliferation of murine and human lymphocytes. Four other peptides, representing different regions of virus proteins, were inactive. These results suggest that the immunosuppressive portion of retroviral transmembrane envelope proteins may reside, at least in part, in a-conserved sequence represented by the CKS-17 peptide.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cianciolo, G J -- Copeland, T D -- Oroszlan, S -- Snyderman, R -- P01-CA29589-02/CA/NCI NIH HHS/ -- R23-CA34671-02/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1985 Oct 25;230(4724):453-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2996136" target="_blank"〉PubMed〈/a〉

    Description: Enhancer sequences are regulatory regions that greatly increase transcription of certain eukaryotic genes. An immunoglobulin heavy-chain variable gene segment is moved from a region lacking enhancer activity to a position adjacent to the known heavy-chain enhancer early in B-cell maturation. In lymphoid cells, the heavy-chain and SV40 enhancers bind a common factor essential for enhancer function. In contrast, fibroblast cells contain a functionally distinct factor that is used by the SV40 but not by the heavy-chain enhancer. The existence of different factors in these cells may explain the previously described lymphoid cell specificity of the heavy-chain enhancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mercola, M -- Goverman, J -- Mirell, C -- Calame, K -- GM29361/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1985 Jan 18;227(4684):266-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3917575" target="_blank"〉PubMed〈/a〉

    Description: During normal mouse development the relative amounts of two types of U1 small nuclear RNA's (U1 RNA) change significantly. Fetal tissues have comparable levels of the two major types of mouse U1 RNA's, mU1a and mU1b, whereas most differentiated adult tissues contain only mU1a RNA's. Those adult tissues that also accumulate detectable amounts of embryonic (mU1b) RNA's (for example, testis, spleen, and thymus) contain a significant proportion of stem cells capable of further differentiation. Several strains of mice express minor sequence variants of U1 RNA's that are subject to the same developmental controls as the major types of adult and embryonic U1 RNA. The differential accumulation of embryonic U1 RNA's may influence the pattern of gene expression during early development and differentiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lund, E -- Kahan, B -- Dahlberg, J E -- CA 33453/CA/NCI NIH HHS/ -- GM 30220/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1985 Sep 20;229(4719):1271-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2412294" target="_blank"〉PubMed〈/a〉

    Description: Multiple copies of a gene that encodes human U1 small nuclear RNA were introduced into mouse C127 cells with bovine papilloma virus as the vector. For some recombinant constructions, the human U1 gene copies were maintained extrachromosomally on the viral episome in an unrearranged fashion. The relative abundance of human and mouse U1 small nuclear RNA varied from one cell line to another, but in some lines human U1 RNA accounted for as much as one-third of the total U1. Regardless of the level of human U1 expression, the total amount of U1 RNA (both mouse and human) in each cell line was nearly the same relative to endogenous mouse 5S or U2 RNA. This result was obtained whether measurements were made of total cellular U1 or of only the U1 in small nuclear ribonucleoprotein particles that could be precipitated with antibody directed against the Sm antigen. The data suggest that the multigene families encoding mammalian U1 RNA are subject to some form of dosage compensation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mangin, M -- Ares, M Jr -- Weiner, A M -- GM09148/GM/NIGMS NIH HHS/ -- GM31073/GM/NIGMS NIH HHS/ -- GM31335/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1985 Jul 19;229(4710):272-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2409601" target="_blank"〉PubMed〈/a〉

    Description: Measles virus generally produces acute illness. Rarely, however, persistent infection of brain cells occurs, resulting in a chronic and fatal neurological disease, subacute sclerosing panencephalitis (SSPE). Evidence indicates that expression of the measles virus matrix protein is selectively restricted in this persistent infection, but the mechanism underlying this restriction has not been identified. Defective translation of matrix messenger RNA has been described in one SSPE cell line. This report presents evidence that in a different SSPE tissue culture cell line IP-3-Ca, the matrix protein is synthesized but fails to accumulate. A general scheme is proposed to reconcile the different levels at which restriction of matrix protein has been observed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sheppard, R D -- Raine, C S -- Bornstein, M B -- Udem, S A -- CA13330-12/CA/NCI NIH HHS/ -- NS 08952/NS/NINDS NIH HHS/ -- NS 11920/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1985 Jun 7;228(4704):1219-21.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/4001938" target="_blank"〉PubMed〈/a〉

    Description: The putative transforming protein of the type I human T-cell leukemia virus (HTLV-1) is a 40-kilodalton protein encoded by the X region and is termed p40XI. On the basis of both subcellular fractionation techniques and immunocytochemical analysis, it is now shown that p40XI is a nuclear protein with a relatively short half-life (120 minutes). It is synthesized de novo in considerable quantities in a human T-cell line infected with and transformed by the virus in vitro, and it is not packaged in detectable amounts in the extracellular virus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Slamon, D J -- Press, M F -- Souza, L M -- Murdock, D C -- Cline, M J -- Golde, D W -- Gasson, J C -- Chen, I S -- CA 32737/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1985 Jun 21;228(4706):1427-30.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2990027" target="_blank"〉PubMed〈/a〉

    Description: The search for new congeners of the leading anticancer drug doxorubicin has led to an analog that is approximately 1000 times more potent, noncardiotoxic at therapeutic dose levels, and non-cross-resistant with doxorubicin. The new anthracycline, 3'-deamino-3'-(3-cyano-4-morpholinyl)doxorubicin (MRA-CN), is produced by incorporation of the 3' amino group of doxorubicin in a new cyanomorpholinyl ring. The marked increase in potency was observed against human ovarian and breast carcinomas in vitro; it was not accompanied by an increase in cardiotoxicity in fetal mouse heart cultures. Doxorubicin and MRA-CN both produced typical cardiac ultrastructural and biochemical changes, but at equimolar concentrations. In addition, MRA-CN was not cross-resistant with doxorubicin in a variant of the human sarcoma cell line MES-SA selected for resistance to doxorubicin. Thus antitumor efficacy was dissociated from both cardiotoxicity and cross-resistance by this modification of anthracycline structure.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sikic, B I -- Ehsan, M N -- Harker, W G -- Friend, N F -- Brown, B W -- Newman, R A -- Hacker, M P -- Acton, E M -- CA 24543/CA/NCI NIH HHS/ -- CA 32250/CA/NCI NIH HHS/ -- CA 33303/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1985 Jun 28;228(4707):1544-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/4012308" target="_blank"〉PubMed〈/a〉

    Description: Human T-cell leukemia virus type III (HTLV-III) was recently identified as the probable etiologic agent of the acquired immune deficiency syndrome (AIDS). Here it is shown that, in human T-cell lines infected with HTLV-III, gene expression directed by the long terminal repeat sequence of this virus is stimulated by more than two orders of magnitude compared to matched uninfected cells. The rate of transcription of the HTLV-III long terminal repeat is more than 1000 times that of the SV40 early promoter in one infected cell line. Thus, HTLV-III, like HTLV-I, HTLV-II, and the bovine leukemia virus, is characterized by trans-activation of transcription in infected cells. The efficiency of trans-activation in the case of HTLV-III may account, at least in part, for the virulent nature of HTLV-III infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sodroski, J -- Rosen, C -- Wong-Staal, F -- Salahuddin, S Z -- Popovic, M -- Arya, S -- Gallo, R C -- Haseltine, W A -- CA07094/CA/NCI NIH HHS/ -- CA07580/CA/NCI NIH HHS/ -- CA36974/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1985 Jan 11;227(4683):171-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2981427" target="_blank"〉PubMed〈/a〉

    Description: Modulation of the growth of human and murine cell lines in vitro by recombinant human tumor necrosis factor-alpha (rTNF-alpha) and recombinant human interferon-gamma (rIFN-gamma) was investigated. rTNF-alpha had cytostatic or cytolytic effects on only some tumor cell lines. When administered together with rIFN-gamma, rTNF-alpha showed enhanced antiproliferative effects on a subset of the cell lines tested. In contrast to its effects on sensitive tumor cells, rTNF-alpha augmented the growth of normal diploid fibroblasts. Variations in the proliferative response induced by rTNF-alpha were apparently not due to differences in either the number of binding sites per cell or their affinity for rTNF-alpha. These observations indicate that the effects of rTNF-alpha on cell growth are not limited to tumor cells, but rather that this protein may have a broad spectrum of activities in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sugarman, B J -- Aggarwal, B B -- Hass, P E -- Figari, I S -- Palladino, M A Jr -- Shepard, H M -- New York, N.Y. -- Science. 1985 Nov 22;230(4728):943-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3933111" target="_blank"〉PubMed〈/a〉

    Description: The classical transplantation antigens (the major histocompatibility complex class I antigens) play a key role in host defense against cells expressing foreign antigens. Several naturally occurring tumors and virally transformed cells show an overall suppression of these surface antigens. Since the class I molecules are required in the presentation of neoantigens on tumor cells to the cytotoxic T lymphocytes, their absence from the cell surface may lead to the escape of these tumors from immunosurveillance. To test this possibility, a functional class I gene was transfected into human adenovirus 12-transformed mouse cells that do not express detectable levels of class I antigens; the transformants were tested for expression of the transfected gene and for changes in oncogenicity. The expression of a single class I gene, introduced by DNA-mediated gene transfer into highly tumorigenic adenovirus 12-transformed cells, was sufficient to abrogate the oncogenicity of these cells. This finding has important implications for the regulation of the malignant phenotype in certain tumors and for the potential modulation of oncogenicity through derepression of the endogenous class I genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tanaka, K -- Isselbacher, K J -- Khoury, G -- Jay, G -- New York, N.Y. -- Science. 1985 Apr 5;228(4695):26-30.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3975631" target="_blank"〉PubMed〈/a〉

    Description: An earlier finding that lymphocytes from African patients with the acquired immune deficiency syndrome (AIDS) react with rabbit antiserum to purified antigens of bovine leukemia virus (BLV) prompted a study of the possible cross-reactions between a BLV-infected ovine cell line and human lymphocytes inoculated with a strain of lymphadenopathy syndrome-associated virus (LAV). A solid-phase radioimmunoassay was used to detect antigenic markers of the retroviruses. Crude extracts from short-term cultures of lymphocytes infected with LAV bound rabbit antisera to the LAV glycoprotein gp13 (molecular weight 13,000) and the BLV proteins p24 and gp51, but did not bind antibodies to the p24 of human T-cell leukemia virus type I (HTLV-I). Antiserum to LAV gp13 reacted with an ovine cell line producing BLV but also weakly with virus-free ovine cells. Lymphocyte cultures from four African patients with AIDS expressed BLV-related antigens within 6 to 10 days of culture, at the moment when particle-bound reverse transcriptase was produced. BLV-related antigens were induced in lymphocyte cultures from healthy individuals by addition of filtered supernatant or irradiated cells of the original culture. The antisera to BLV used in this study may prove useful for the detection of AIDS-associated viruses in short-term cultures of lymphocytes from AIDS patients or their contacts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thiry, L -- Sprecher-Goldberger, S -- Jacquemin, P -- Cogniaux, J -- Burny, A -- Bruck, C -- Portetelle, D -- Cran, S -- Clumeck, N -- New York, N.Y. -- Science. 1985 Mar 22;227(4693):1482-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2579433" target="_blank"〉PubMed〈/a〉

    Description: Clones of complementary DNA encoding the human lymphokine known as granulocyte-macrophage colony-stimulating factor (GM-CSF) were isolated by means of a mammalian cell (monkey COS cell) expression screening system. One of these clones was used to produce recombinant GM-CSF in mammalian cells. The recombinant hematopoietin was similar to the natural product that was purified to apparent homogeneity from medium conditioned by a human T-cell line. The human T-cell GM-CSF was found to be 60 percent homologous with the GM-CSF recently cloned from murine lung messenger RNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wong, G G -- Witek, J S -- Temple, P A -- Wilkens, K M -- Leary, A C -- Luxenberg, D P -- Jones, S S -- Brown, E L -- Kay, R M -- Orr, E C -- New York, N.Y. -- Science. 1985 May 17;228(4701):810-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3923623" target="_blank"〉PubMed〈/a〉

    Description: Transfection of normal human bronchial epithelial (NHBE) cells with a plasmid carrying the ras oncogene of Harvey murine sarcoma virus (v-Ha ras) changed the growth requirements, terminal differentiation, and tumorigenicity of the recipient cells. One of the cell lines isolated after transfection (TBE-1) was studied extensively and shown to contain v-Ha ras DNA. Total cellular RNA from TBE-1 cells hybridized to v-Ha ras structural gene fragment probes five to eight times more than RNA from parental NHBE cells. The TBE-1 cells expressed phosphorylated v-Ha ras polypeptide p21, showed a reduced requirement for growth-factor supplements, and became aneuploid as an early cellular response to v-Ha ras expression. As the transfectants acquire an indefinite life-span and anchorage independence they became transplantable tumor cells and showed many phenotypic changes suggesting a pleiotropic mechanism for the role of Ha ras in human carcinogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoakum, G H -- Lechner, J F -- Gabrielson, E W -- Korba, B E -- Malan-Shibley, L -- Willey, J C -- Valerio, M G -- Shamsuddin, A M -- Trump, B F -- Harris, C C -- New York, N.Y. -- Science. 1985 Mar 8;227(4691):1174-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3975607" target="_blank"〉PubMed〈/a〉

    Description: The circumsporozoite (CS) protein of the human malaria parasite Plasmodium falciparum may be the most promising target for the development of a malaria vaccine. In this study, proteins composed of 16, 32, or 48 tandem copies of a tetrapeptide repeating sequence found in the CS protein were efficiently expressed in the bacterium Escherichia coli. When injected into mice, these recombinant products resulted in the production of high titers of antibodies that reacted with the authentic CS protein on live sporozoites and blocked sporozoite invasion of human hepatoma cells in vitro. These CS protein derivatives are therefore candidates for a human malaria vaccine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Young, J F -- Hockmeyer, W T -- Gross, M -- Ballou, W R -- Wirtz, R A -- Trosper, J H -- Beaudoin, R L -- Hollingdale, M R -- Miller, L H -- Diggs, C L -- New York, N.Y. -- Science. 1985 May 24;228(4702):958-62.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2988125" target="_blank"〉PubMed〈/a〉

    Description: Alterations in proto-oncogene expression after stimulation of rat pheochromocytoma (PC12) cells by nerve growth factor (NGF) have been investigated. A specific stimulation of c-fos messenger RNA and protein was detected 30 minutes after treatment. This induction was enhanced more than 100-fold in the presence of peripherally active benzodiazepines. The effect was specific as very little change was observed in the levels of c-rasHa, c-rasKi, c-myc, and N-myc messenger RNA's. Under the conditions used here, NGF treatment ultimately results in neurite outgrowth, with a reduction or cessation of cell division. Thus, stimulation of the c-fos gene in this system appeared to be associated with differentiation and not with cellular proliferation. The effect of benzodiazepines was stereospecific and represents a novel action of these compounds at the level of gene expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Curran, T -- Morgan, J I -- New York, N.Y. -- Science. 1985 Sep 20;229(4719):1265-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/4035354" target="_blank"〉PubMed〈/a〉

    Description: The immunoglobulin kappa (kappa) gene promoter was activated by a "neutral" enhancer derived from Harvey murine sarcoma virus (HaMuSV) in immunoglobulin-producing myeloma cells, regardless of the enhancer's orientation or position in the vector. In one fibroblast line (3T3) the immunoglobulin kappa gene promoter was completely inactive when linked to the HaMuSV enhancer, whereas in mouse L cells, promoter activity was observed only with the HaMuSV enhancer in tandem with the immunoglobulin kappa gene promoter. The differential behavior of the gene promoter, when activated by a neutral enhancer in these three murine cell lines, suggests that promoter sequences contribute to the tissue-specific expression of this gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gopal, T V -- Shimada, T -- Baur, A W -- Nienhuis, A W -- New York, N.Y. -- Science. 1985 Sep 13;229(4718):1102-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2994213" target="_blank"〉PubMed〈/a〉

    Description: Substantial evidence suggests that calcium has a pivotal role in regulating the initial events through which insulin alters plasma membrane metabolism. Because binding of insulin to its receptor represents the initial site of insulin action in the plasma membrane, studies were undertaken to determine whether the insulin receptor is a calmodulin-binding protein. Preparations enriched in the insulin receptor and calmodulin-binding proteins were isolated from detergent-solubilized rat adipocyte membranes by chromatography with wheat germ agglutinin agarose and calmodulin-conjugated Sepharose, respectively. Substantial purification of a manganese-dependent, insulin-sensitive phosphoprotein of 95K identified as the beta subunit of the insulin receptor was accomplished. Binding and photocovalent cross-linking of iodine-125-labeled calmodulin to these affinity-purified preparations and to isolated plasma membranes, followed by immunoadsorption with insulin receptor antibodies bound to protein A Sepharose, resulted in significant purification of a binding complex of 110K to 140K. These results indicate that the adipocyte insulin receptor or a polypeptide closely associated with the receptor is a calmodulin-binding protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Graves, C B -- Goewert, R R -- McDonald, J M -- AM-25897/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1985 Nov 15;230(4727):827-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3904001" target="_blank"〉PubMed〈/a〉

    Description: Visna virus is a pathogenic lentivirus of sheep that is related to human T-cell lymphotropic virus type III (HTLV-III), the probable etiologic agent of the acquired immune deficiency syndrome (AIDS). The transcriptional activity of visna virus promoter and enhancer sequences was studied by means of an assay based on the transient expression of the bacterial gene chloramphenicol acetyltransferase (CAT). The results suggest that the high level of expression of visna virus is due in part to cis-acting enhancer sequences that give the viral promoter a high level of transcriptional activity. In addition, the rate of transcription from the visna virus promoter situated in a plasmid expressing the CAT gene was much greater in infected than uninfected cells. This phenomenon of trans-acting transcriptional activation may involve either virally or cellularly encoded factors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hess, J L -- Clements, J E -- Narayan, O -- NS-15721/NS/NINDS NIH HHS/ -- NS-16145/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1985 Aug 2;229(4712):482-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2990051" target="_blank"〉PubMed〈/a〉

    Description: Human granulocyte-macrophage colony-stimulating factor (GM-CSF) is a 22,000-dalton glycoprotein that stimulates the growth of myeloid progenitor cells and acts directly on mature neutrophils. A full-length complementary DNA clone encoding human GM-CSF was used as a probe to screen a human genomic library and isolate the gene encoding human GM-CSF. The human GM-CSF gene is approximately 2.5 kilobase pairs in length with at least three intervening sequences. The GM-CSF gene was localized by somatic cell hybrid analysis and in situ hybridization to human chromosome region 5q21-5q32, which is involved in interstitial deletions in the 5q- syndrome and acute myelogenous leukemia. An established, human promyelocytic leukemia cell line, HL60, contains a rearranged, partially deleted GM-CSF allele and a candidate 5q- marker chromosome, indicating that the truncated GM-CSF allele may reside at the rejoining point for the interstitial deletion on the HL60 marker chromosome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huebner, K -- Isobe, M -- Croce, C M -- Golde, D W -- Kaufman, S E -- Gasson, J C -- CA-10805/CA/NCI NIH HHS/ -- CA-16685/CA/NCI NIH HHS/ -- CA-21124/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1985 Dec 13;230(4731):1282-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2999978" target="_blank"〉PubMed〈/a〉

    Description: The T-cell receptor for antigen (Ti) was purified from the human tumor cell line HPB-ALL. Amino-terminal sequence analysis of an acid-cleaved peptide of the Ti alpha chain showed that it is highly homologous to a putative murine alpha chain recently described. Amino-terminal sequence analysis of the Ti beta chain revealed that it shares 50 percent homology with the Ti beta chain amino acid sequences from two other human T-cell tumors. Nucleotide sequence analysis of a complementary DNA clone encoding the Ti beta chain from the HPB-MLT cell line showed that this chain represents a second human constant region gene segment and suggested that it arises from direct joining of the variable and joining gene segments without any intervening D region sequences.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jones, N -- Leiden, J -- Dialynas, D -- Fraser, J -- Clabby, M -- Kishimoto, T -- Strominger, J L -- Andrews, D -- Lane, W -- Woody, J -- 5 R01 AI15669/AI/NIAID NIH HHS/ -- AI10736/AI/NIAID NIH HHS/ -- Y001CP00502/CP/NCI NIH HHS/ -- New York, N.Y. -- Science. 1985 Jan 18;227(4684):311-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3871253" target="_blank"〉PubMed〈/a〉

    Description: The environmental contaminant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) may produce its effects by altering gene expression in susceptible cells. In mouse hepatoma cells, TCDD induces the transcription of the cytochrome P1-450 gene, whose product, aryl hydrocarbon hydroxylase, contributes both to the detoxification and to the metabolic activation of carcinogenic polycyclic aromatic hydrocarbons. A DNA fragment containing sequences flanking the 5' end of the cytochrome P1-450 gene was isolated and analyzed. This DNA fragment contains a cis-acting control element with at least three functional domains: a putative promoter, an inhibitory domain upstream from the promoter that blocks its function, and a TCDD-responsive domain still farther (1265 to 1535 base pairs) upstream of the promoter. These findings, together with results from earlier studies, imply that transcription of the cytochrome P1-450 gene is under both positive and negative control by at least two trans-acting regulatory factors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jones, P B -- Galeazzi, D R -- Fisher, J M -- Whitlock, J P Jr -- CA09302/CA/NCI NIH HHS/ -- CA32786/CA/NCI NIH HHS/ -- GM07149/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1985 Mar 22;227(4693):1499-502.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3856321" target="_blank"〉PubMed〈/a〉

    Description: Induction of cytochrome P1-450 has been linked to susceptibility to certain chemically induced cancers in mouse and man. Treatment of the human cell line MCF-7 with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) results in high levels of aryl hydrocarbon (benzo[a]pyrene) hydroxylase (P1-450) activity. This cell line was used to isolate a human P1-450 full-length complementary DNA (cDNA) clone. The cDNA is 2566 nucleotides in length, encodes a polyadenylated messenger RNA (2.8 kilobases in length), and has a continuous reading frame producing a protein with 512 residues (molecular weight, 58,151). The human P1-450 cDNA and protein are 63 percent and 80 percent similar to mouse P1-450 cDNA and protein, respectively. Whereas the mouse TCDD-inducible P-450 gene subfamily has two members (P1-450 and P3-450), the human TCDD-inducible gene subfamily appears to have only one gene (P1-450).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jaiswal, A K -- Gonzalez, F J -- Nebert, D W -- New York, N.Y. -- Science. 1985 Apr 5;228(4695):80-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3838385" target="_blank"〉PubMed〈/a〉

Crawford, the findings of a General Accounting Office report on the operating costs of the Continuous Electron Beam Accelerator Facility (CEBAF) were overstated. The report found that the Department of Energy's operating costs would rise by $80 million if both CEBAF and the Relativistic Heavy Ion Collider are constructed. CEBAF's operating cost is estimated to be $30 million. The report also found problems in accommodating the operating costs of the proposed Superconducting Super Collider in the department's budget.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaslow, R A -- New York, N.Y. -- Science. 1985 Jul 5;229(4708):8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/4012314" target="_blank"〉PubMed〈/a〉

    Description: The natural history of estrogen-responsive breast cancers often involves a phenotypic change to an estrogen-unresponsive, more aggressive tumor. The human breast cancer cell line, MCF-7, which requires estradiol for tumor formation in vivo and shows growth stimulation in response to estradiol in vitro, is a model for hormone-responsive tumors. The v-rasH onc gene was transfected into MCF-7 cells. The cloned MCF-7ras transfectants, which expressed the v-rasH messenger RNA and v-rasH p21 protein (21,000 daltons), were characterized. In contrast to the parental cell line, MCF-7ras cells no longer responded to exogenous estrogen in culture and their growth was minimally inhibited by exogenous antiestrogens. When tested in the nude mouse, the MCF-7ras cells were fully tumorigenic in the absence of estrogen supplementation. Thus, cells acquiring an activated onc gene can bypass the hormonal regulatory signals that trigger the neoplastic growth of a human breast cancer cell line.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kasid, A -- Lippman, M E -- Papageorge, A G -- Lowy, D R -- Gelmann, E P -- New York, N.Y. -- Science. 1985 May 10;228(4700):725-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/4039465" target="_blank"〉PubMed〈/a〉

    Description: Complementary DNA (cDNA) clones encoding human macrophage-specific specific colony-stimulating factor (CSF-1) were isolated. One cDNA clone codes for a mature polypeptide of 224 amino acids and a putative leader of 32 amino acids. This cDNA, which was cloned in the Okayama-Berg expression vector, specifies the synthesis of biologically active CSF-1 in COS cells, as determined by a specific radioreceptor assay, macrophage bone marrow colony formation, and antibody neutralization. Most of the cDNA isolates contain part of an intron sequence that changes the reading frame, resulting in an abrupt termination of translation; these cDNA's were inactive in COS cells. The CSF-1 appears to be encoded by a single-copy gene, but its expression results in the synthesis of several messenger RNA species, ranging in size from about 1.5 to 4.5 kilobases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kawasaki, E S -- Ladner, M B -- Wang, A M -- Van Arsdell, J -- Warren, M K -- Coyne, M Y -- Schweickart, V L -- Lee, M T -- Wilson, K J -- Boosman, A -- C32551/PHS HHS/ -- New York, N.Y. -- Science. 1985 Oct 18;230(4723):291-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2996129" target="_blank"〉PubMed〈/a〉

    Description: Protein secretion from cells can take several forms. Secretion is constitutive if proteins are secreted as fast as they are synthesized. In regulated secretion newly synthesized proteins destined for secretion are stored at high concentration in secretory vesicles until the cell receives an appropriate stimulus. When both constitutive and regulated protein secretion can take place in the same cell a mechanism must exist for sorting the correct secretory protein into the correct secretory vesicle. The secretory vesicle must then be delivered to the appropriate region of plasma membrane. Transfection of DNA encoding foreign secretory proteins into regulated secretory cells has provided insight into the specificity of sorting into secretory vesicles.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kelly, R B -- New York, N.Y. -- Science. 1985 Oct 4;230(4721):25-32.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2994224" target="_blank"〉PubMed〈/a〉

    Description: The changes in the political economy of science are the natural outcome of two trends: science itself has become a more capital-intensive activity at the same time that federal support for research programs has slowed its growth. The results of the accumulating shortfall in the capital base for university research--increased seeking of support from private industry, efforts to circumvent peer review and competitive allocation, and a falling-out between institutions and investigators over how to divide up available resources--threaten to unravel what has been an extraordinary way of doing science.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kennedy, D -- New York, N.Y. -- Science. 1985 Feb 1;227(4686):480-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3966157" target="_blank"〉PubMed〈/a〉

    Description: The cellular gene encoding the receptor for epidermal growth factor (EGF) has considerable homology to the oncogene of avian erythroblastosis virus. In a human mammary carcinoma, a DNA sequence was identified that is related to v-erbB but amplified in a manner that appeared to distinguish it from the gene for the EGF receptor. Molecular cloning of this DNA segment and nucleotide sequence analysis revealed the presence of two putative exons in a DNA segment whose predicted amino acid sequence was closely related to, but different from, the corresponding sequence of the erbB/EGF receptor. Moreover, this DNA segment identified a 5-kilobase transcript distinct from the transcripts of the EGF receptor gene. Thus, a new member of the tyrosine kinase proto-oncogene family has been identified on the basis of its amplification in a human mammary carcinoma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉King, C R -- Kraus, M H -- Aaronson, S A -- New York, N.Y. -- Science. 1985 Sep 6;229(4717):974-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2992089" target="_blank"〉PubMed〈/a〉

    Description: The expression of a previously unidentified gene product, encoded by the hepatitis B virus (HBV) genome, has been achieved with a recombinant SV40 expression vector. Antibodies against synthetic peptides representing defined regions of this protein were used to screen cells infected with recombinant virus as well as tissues naturally infected with HBV. A 24,000-dalton protein (p24) was detected in cells infected with recombinant virus and a 28,000-dalton protein (p28) was detected in tissues infected with HBV. The peptides or recombinant-derived protein were used as antigens to screen sera from individuals infected with HBV. Specific antibodies were detected predominantly in sera from patients with hepatocellular carcinoma. The presence of p28 in tissues infected with HBV and the appearance of specific antibodies in infectious sera establish the existence of an additional marker for HBV infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moriarty, A M -- Alexander, H -- Lerner, R A -- Thornton, G B -- New York, N.Y. -- Science. 1985 Jan 25;227(4685):429-33.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2981434" target="_blank"〉PubMed〈/a〉

    Description: In several bursal lymphoma cell lines in which c-myc transcription is regulated by avian leukosis virus (ALV) long terminal repeat (LTR) sequences, protein synthesis inhibition decreases the transcriptional activity of c-myc as well as other LTR driven viral genes. This decrease in transcription is associated with a change in the chromatin structure of c-myc, as measured by deoxyribonuclease I (DNase I) hypersensitivity, and a shift of transcription from the LTR to the normal c-myc promoter. In contrast, cycloheximide had little or no effect on the transcription of LTR driven genes in infected chicken embryo fibroblasts treated with the drug. These results suggest that a labile, cell type-specific protein may interact with the retroviral LTR and regulate transcription of genes under LTR control. Further, the results demonstrate that the increase in intracellular concentration of c-myc RNA induced by cycloheximide treatment of normal cells is the result of stabilization of this message.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Linial, M -- Gunderson, N -- Groudine, M -- CA 18282/CA/NCI NIH HHS/ -- CA 28151/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1985 Dec 6;230(4730):1126-32.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2999973" target="_blank"〉PubMed〈/a〉

Partial V8 protease mapping indicated that the increased phosphorylation occurred exclusively on serine residues located in the amino terminus of the molecule. Treatment of cells with dimethyl sulfoxide or 4 alpha-phorbol-12,13-didecanoate did not elicit this response. Two-dimensional tryptic phosphopeptide mapping of pp60v-src immunoprecipitated from untreated and TPA-treated cells indicated that a specific tryptic amino-terminal peptide was hyperphosphorylated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Purchio, A F -- Shoyab, M -- Gentry, L E -- New York, N.Y. -- Science. 1985 Sep 27;229(4720):1393-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2994221" target="_blank"〉PubMed〈/a〉

    Description: Human tissues have carbon-isotope ratios (13C/12C) that reflect dietary ratios. This observation has been used to determine the extent of metabolic turnover of DNA in cells of the adult human cerebellum (90 percent of which are neuronal). If adult human neuronal DNA were metabolically stable, its 13C/12C would reflect that in the maternal diet during fetal development as nearly all neurons are formed during maturation of the fetal brain and do not undergo cell division thereafter. The 13C/12C ratios in the food chains and body tissues of Europeans differ from corresponding American ratios by about 50 parts per million on the average. Therefore, turnover was studied by comparing 13C/12C ratios in cerebellar DNA of American-born Americans, European-born Americans, and European-born Europeans. The 13C/12C ratios in cerebellar DNA from European-born Americans were closer to 13C/12C ratios in cerebellar DNA from European-born Europeans than from American-born Americans, indicating that there was little or no turnover of neuronal DNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Slatkin, D N -- Friedman, L -- Irsa, A P -- Micca, P L -- NS 17822-01 RNM/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1985 May 24;228(4702):1002-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/4001927" target="_blank"〉PubMed〈/a〉

    Description: Tumor necrosis factor (TNF) is a soluble protein that causes damage to tumor cells but has no effect on normal cells. Human TNF was purified to apparent homogeneity as a 17.3-kilodalton protein from HL-60 leukemia cells and showed cytotoxic and cytostatic activities against various human tumor cell lines. The amino acid sequence was determined for the amino terminal end of the purified protein, and oligodeoxyribonucleotide probes were synthesized on the basis of this sequence. Complementary DNA (cDNA) encoding human TNF was cloned from induced HL-60 messenger RNA and was confirmed by hybrid-selection assay, direct expression in COS-7 cells, and nucleotide sequence analysis. The human TNF cDNA is 1585 base pairs in length and encodes a protein of 233 amino acids. The mature protein begins at residue 77, leaving a long leader sequence of 76 amino acids. Expression of high levels of human TNF in Escherichia coli was accomplished under control of the bacteriophage lambda PL promoter and gene N ribosome binding site.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, A M -- Creasey, A A -- Ladner, M B -- Lin, L S -- Strickler, J -- Van Arsdell, J N -- Yamamoto, R -- Mark, D F -- New York, N.Y. -- Science. 1985 Apr 12;228(4696):149-54.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3856324" target="_blank"〉PubMed〈/a〉

    Description: The functional activity of the promoter unit contained within the long terminal repeat (LTR) of bovine leukemia virus (BLV) was examined by monitoring transient expression of a heterologous gene placed under its control. Various cell lines were transfected with recombinant plasmids carrying the bacterial chloramphenicol acetyltransferase (CAT) gene coupled to the BLV LTR (pBL-cat). Transient expression of CAT activity directed by the BLV LTR was observed only in the established BLV-producer cell lines derived from fetal lamb kidney (FLK) cells and bat lung cells. The amount of CAT activity transiently expressed in FLK-BLV cells was decreased approximately tenfold by deletion of LTR sequences located within a region 100 to 170 nucleotides upstream of the RNA start site. Surprisingly, removal of the region 50 base pairs downstream of the RNA initiation site to the 3'-end of the LTR reduced the expression of CAT activity by 87 percent. The BLV LTR thus appears to be an unusual promoter unit, functioning in a cell type-specific manner and possessing sequences on both the 5' and 3' sides of the RNA start site that influence gene expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Derse, D -- Caradonna, S J -- Casey, J W -- CA07392/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1985 Jan 18;227(4684):317-20.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2981431" target="_blank"〉PubMed〈/a〉

    Description: The phosphorylation of 2-deoxyglucose by the mammalian brain is used as an index of the brain's energy metabolism. The results of phosphorus-31 nuclear magnetic resonance (31P NMR) monitoring of conscious animals in vivo showed rapid phosphorylation of 2-deoxyglucose by brain tissue. The rate of phosphorylation as determined by 31P NMR was consistent with results achieved by tracer methods using carbon-14-labeled 2-deoxyglucose. However, the disappearance of 2-deoxyglucose-6-phosphate was shown to be faster than that reported by tracer studies and occurred without alterations of intracellular pH and energy homeostasis. These results were confirmed by gas chromatography and mass spectroscopy. It is postulated that 2-deoxyglucose may be metabolized in several ways, including dephosphorylation by a hexose phosphatase.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deuel, R K -- Yue, G M -- Sherman, W R -- Schickner, D J -- Ackerman, J J -- AM-20579/AM/NIADDK NIH HHS/ -- GM-30331/GM/NIGMS NIH HHS/ -- RR 00954/RR/NCRR NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1985 Jun 14;228(4705):1329-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/4001946" target="_blank"〉PubMed〈/a〉
