    Circumsporozoite protein of Plasmodium vivax: gene cloning and characterization of the immunodominant epitope (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-11-15
    Description: The gene encoding the circumsporozoite (CS) protein of the human malaria parasite Plasmodium vivax has been cloned. The deduced sequence of the protein consists of 373 amino acids with a central region of 19 tandem repeats of the nonapeptide Asp-Arg-Ala-Asp/Ala-Gly-Gln-Pro-Ala-Gly. A synthetic 18-amino acid peptide containing two tandem repeats binds to a monoclonal antibody directed to the CS protein of Plasmodium vivax and inhibits the interaction of this antibody with the native protein in sporozoite extracts. The portions of the CS gene that do not contain repeats are closely related to the corresponding regions of the CS genes of two simian malarias, Plasmodium cynomolgi and Plasmodium knowlesi. In contrast, the homology between the CS genes of Plasmodium vivax and Plasmodium falciparum, another malaria parasite of humans, is very limited.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arnot, D E -- Barnwell, J W -- Tam, J P -- Nussenzweig, V -- Nussenzweig, R S -- Enea, V -- New York, N.Y. -- Science. 1985 Nov 15;230(4727):815-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2414847" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1985-05-24
    Description: The gene for the RNA subunit (M1 RNA) of ribonuclease P from Salmonella typhimurium directs the synthesis of an RNA that can cleave transfer RNA precursor molecules. The mature M1 RNA coded for by Salmonella typhimurium is 375 nucleotides long and has six nucleotide changes in comparison to M1 RNA from Escherichia coli. The regions for promotion and termination of transcription are closely conserved, but adjacent regions of nucleotide sequences show considerable drift.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baer, M -- Altman, S -- GM19422/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1985 May 24;228(4702):999-1002.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2408335" target="_blank"〉PubMed〈/a〉

    T-cell receptor beta-chain expression: dependence on relatively few variable region genes (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-08-09
    Description: Fifteen independently isolated complementary DNA clones that contain T-cell receptor (TCR) V beta genes were sequenced and found to represent 11 different V beta genes. When compared with known sequences, 14 different V beta genes could be defined from a total of 25 complementary DNA's; 11 clones therefore involved repeated usage of previously identified V beta's. Based on these data, we calculate a maximum likelihood estimate of the number of expressed germline V beta genes to be 18 with an upper 95 percent confidence bound of 30 genes. Southern blot analysis has shown that most of these genes belong to single element subfamilies which show very limited interstrain polymorphism. The TCR beta-chain diversity appears to be generated from a limited V beta gene pool primarily by extensive variability at the variable-diversity-joining (V-D-J) junctional site, with no evidence for the involvement of somatic hypermutation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Behlke, M A -- Spinella, D G -- Chou, H S -- Sha, W -- Hartl, D L -- Loh, D Y -- GM07200/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1985 Aug 9;229(4713):566-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3875151" target="_blank"〉PubMed〈/a〉

    Genomic heterogeneity of AIDS retroviral isolates from North America and Zaire (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-11-22
    Description: In an analysis of the genomic variation of AIDS retroviral isolates from patients living in New York, Alabama, and Zaire, restriction maps were constructed by using seven enzymes, each known to cleave the proviral DNA more than once, in conjunction with Southern blot analysis. The maps of LAV, HTLV-III, and ARV-2 as deduced from their published nucleotide sequences were included in this analysis. The results demonstrated that (i) several "signature" restriction sites were common to all isolates; (ii) with the exception of LAV and HTLV-III, the North American and European isolates were all different from one another and showed no geographical specificity; (iii) the African isolates as a group were more diverse than those from North America and Europe; and (iv) the genomic variability was concentrated within the env gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Benn, S -- Rutledge, R -- Folks, T -- Gold, J -- Baker, L -- McCormick, J -- Feorino, P -- Piot, P -- Quinn, T -- Martin, M -- New York, N.Y. -- Science. 1985 Nov 22;230(4728):949-51.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2997922" target="_blank"〉PubMed〈/a〉

    Protection from genital herpes simplex virus type 2 infection by vaccination with cloned type 1 glycoprotein D (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-03-22
    Description: Guinea pigs were vaccinated with truncated herpes simplex virus type-1 (HSV-1) glycoprotein D produced in the genetically engineered mammalian cell line gD10.2. Vaccinated animals formed antibodies that neutralized both HSV-1 and herpes simplex virus type 2 (HSV-2) in an in vitro neutralization assay. Vaccinated animals were challenged with HSV-2 by intravaginal infection. Animals that received the immunogen in Freund's complete adjuvant were completely protected from the clinical manifestations of genital HSV-2 infection. Animals that received the immunogen incorporated in alum adjuvants were partly protected from clinical disease; the infections that did develop were significantly less severe than those that occurred in control animals injected with adjuvant alone. The results demonstrate that immunization with a purified viral protein can provide significant protection against primary genital infection by HSV-2 in guinea pigs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berman, P W -- Gregory, T -- Crase, D -- Lasky, L A -- New York, N.Y. -- Science. 1985 Mar 22;227(4693):1490-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2983428" target="_blank"〉PubMed〈/a〉

    A new class of endogenous human retroviral genomes (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-06-07
    Description: Human DNA contains multiple copies of a novel class of endogenous retroviral genomes. Analysis of a human recombinant DNA clone (HLM-2) containing one such proviral genome revealed that it is a mosaic of retroviral-related sequences with the organization and length of known endogenous retroviral genomes. The HLM-2 long terminal repeat hybridized with the long terminal repeat of the squirrel monkey virus, a type D retrovirus. The HLM-2 gag and pol genes share extensive nucleotide sequence homology with those of the M432 retrovirus (a type A-related retrovirus), mouse mammary tumor virus (a type B retrovirus), and the avian Rous sarcoma virus (a type C retrovirus). Nucleotide sequence analysis revealed regions in the HLM-2 pol gene that were as much as 70 percent identical to the mouse mammary tumor virus pol gene. A portion of the putative HLM-2 env gene hybridized with the corresponding region of the M432 viral genome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Callahan, R -- Chiu, I M -- Wong, J F -- Tronick, S R -- Roe, B A -- Aaronson, S A -- Schlom, J -- GM30400/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1985 Jun 7;228(4704):1208-11.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2408338" target="_blank"〉PubMed〈/a〉

    Expression in Escherichia coli of open reading frame gene segments of HTLV-III (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-04-05
    Description: Human T-cell lymphotropic virus type III (HTLV-III), the causative agent of the acquired immune deficiency syndrome (AIDS), was recently isolated and its genomic structure analyzed by DNA cloning methods. In the studies reported here a combined cloning and expression system was used to identify HTLV-III encoded peptides that react immunologically with antibodies in sera from AIDS patients. Cloned HTLV-III DNA was sheared into approximately 500-base-pair fragments and inserted into an "open reading frame" expression vector, pMR100. The inserted DNA was expressed in Escherichia coli transformants as a polypeptide fused to the lambda CI protein at its amino terminus and to beta-galactosidase at its carboxyl terminus. Sera from AIDS patients containing antibodies to HTLV-III were then used to screen for immunoreactive fusion proteins. Twenty clones, each specifying a fusion protein strongly reactive with AIDS serum, were identified. DNA sequence analysis indicated that the HTLV-III fragments were derived from the open reading frame DNA segments corresponding to the gag and pol gene coding regions and also the large open reading frame region (env-lor) located near the 3' end of the viral genome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chang, N T -- Chanda, P K -- Barone, A D -- McKinney, S -- Rhodes, D P -- Tam, S H -- Shearman, C W -- Huang, J -- Chang, T W -- Gallo, R C -- New York, N.Y. -- Science. 1985 Apr 5;228(4695):93-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2983429" target="_blank"〉PubMed〈/a〉

    Brain "identifier sequence" is not restricted to brain: similar abundance in nuclear RNA of other organs (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-09-20
    Description: A repeated 82 base pair sequence in genomic DNA of the rat was previously proposed as being a control element governing brain (neuron) specific genetic expression. This intronic sequence, termed the brain "identifier" (ID), is complementary to small RNA species localized in brain cytoplasm, and it was thought to be represented specifically in RNA produced by brain nuclei in vitro. The RNA blot analyses of total nuclear and polyadenylated heterogeneous nuclear RNA described in the present report show that this ID sequence is also present in the liver and kidney in abundances similar to those in the brain. This repeated sequence is not, therefore, restricted to transcripts produced in the brain as suggested from previous transcriptional "runoff" experiments. Measurements on rat and mouse nuclear RNA indicate that the abundance of ID sequence transcript is roughly proportional to the number of copies of this repeat in the respective genomes. This suggests a rather random genomic location and transcription of this sequence. From these results it seems improbable that the ID sequence functions as a transcriptional-level control element in genes expressed specifically in the brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Owens, G P -- Chaudhari, N -- Hahn, W E -- NS10813/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1985 Sep 20;229(4719):1263-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2412293" target="_blank"〉PubMed〈/a〉

    Cassette of eight exons shared by genes for LDL receptor and EGF precursor (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-05-17
    Description: The amino acid sequences of the human low-density lipoprotein (LDL) receptor and the human precursor for epidermal growth factor (EGF) show 33 percent identity over a stretch of 400 residues. This region of homologous is encoded by eight contiguous exons in each respective gene. Of the nine introns that separate these exons, five are located in identical positions in the two protein sequences. This finding suggests that the homologous region may have resulted from a duplication of an ancestral gene and that the two genes evolved further by recruitment of exons from other genes, which provided the specific functional domains of the LDL receptor and the EGF precursor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sudhof, T C -- Russell, D W -- Goldstein, J L -- Brown, M S -- Sanchez-Pescador, R -- Bell, G I -- HL 01287/HL/NHLBI NIH HHS/ -- HL 20948/HL/NHLBI NIH HHS/ -- HL 31346/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1985 May 17;228(4701):893-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3873704" target="_blank"〉PubMed〈/a〉

    The LDL receptor gene: a mosaic of exons shared with different proteins (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-05-17
    Description: The multifunctional nature of coated pit receptors predicts that these proteins will contain multiple domains. To establish the genetic basis for these domains (LDL) receptor. This gene is more than 45 kilobases in length and contains 18 exons, most of which correlate with functional domains previously defined at the protein level. Thirteen of the 18 exons encode protein sequences that are homologous to sequences in other proteins: five of these exons encode a sequence similar to one in the C9 component of complement; three exons encode a sequence similar to a repeat sequence in the precursor for epidermal growth factor (EGF) and in three proteins of the blood clotting system (factor IX, factor X, and protein C); and five other exons encode nonrepeated sequences that are shared only with the EGF precursor. The LDL receptor appears to be a mosaic protein built up of exons shared with different proteins, and it therefore belongs to several supergene families.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4450672/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4450672/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sudhof, T C -- Goldstein, J L -- Brown, M S -- Russell, D W -- HL 01287/HL/NHLBI NIH HHS/ -- HL 20948/HL/NHLBI NIH HHS/ -- HL 31346/HL/NHLBI NIH HHS/ -- P01 HL020948/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1985 May 17;228(4701):815-22.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2988123" target="_blank"〉PubMed〈/a〉

    Description: A complementary DNA library was constructed from messenger RNA's extracted from the brains of mice infected with the scrapie agent. The library was differentially screened with the objectives of finding clones that might be used as markers of infection and finding clones of genes whose increased expression might be correlated with the pathological changes common to scrapie and Alzheimer's disease. A gene was identified whose expression is increased in scrapie. The complementary DNA corresponding to this gene hybridized preferentially and focally to cells in the brains of scrapie-infected animals. The cloned DNA also hybridized to the neuritic plaques found with increased frequency in brains of patients with Alzheimer's disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wietgrefe, S -- Zupancic, M -- Haase, A -- Chesebro, B -- Race, R -- Frey, W 2nd -- Rustan, T -- Friedman, R L -- New York, N.Y. -- Science. 1985 Dec 6;230(4730):1177-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3840915" target="_blank"〉PubMed〈/a〉

    Publication Date: 1985-05-24
    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.

    Description: Deoxyoligonucleotides can now be synthesized rapidly and in high yield because of recent advances in nucleic acid chemistry. Key innovations include solid-phase synthesis on silica-based supports and the development of stable deoxynucleoside phosphoramidites as synthons. When incorporated into manual, semiautomatic, or automatic instruments, these new procedures can be used to prepare probes, mixed probes, deoxyoligonucleotides for priming DNA synthesis, analogues of deoxyoligonucleotides, and DNA segments containing more than 100 deoxynucleotides.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Caruthers, M H -- GM21120/GM/NIGMS NIH HHS/ -- GM25680/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1985 Oct 18;230(4723):281-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3863253" target="_blank"〉PubMed〈/a〉

    Human von Willebrand factor (vWF): isolation of complementary DNA (cDNA) clones and chromosomal localization (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-06-21
    Description: Human factor VIII--von Willebrand factor (vWF) is a large, multimeric glycoprotein that plays a central role in the blood coagulation system, serving both as a carrier for factor VIIIC (antihemophilic factor) and as a major mediator of platelet-vessel wall interaction. Diminished or abnormal vWF activity results in von Willebrand's disease (vWD), a common and complex hereditary bleeding disorder. Overlapping vWF cDNA clones that span 8.2 kilobases of the vWF messenger RNA have been obtained. vWF accounts for approximately 0.3 percent of endothelial cell messenger RNA and was undetectable in several other tissues examined. A large single copy gene for vWF is located on the short arm of chromosome 12 (12p12----12pter). No gross gene rearrangement or deletion was detected in the DNA of two patients with severe vWD.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ginsburg, D -- Handin, R I -- Bonthron, D T -- Donlon, T A -- Bruns, G A -- Latt, S A -- Orkin, S H -- New York, N.Y. -- Science. 1985 Jun 21;228(4706):1401-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3874428" target="_blank"〉PubMed〈/a〉

    Spatially regulated expression of homeotic genes in Drosophila (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-09-20
    Description: The sites of transcript accumulation for six different homeotic loci of the Antennapedia and bithorax gene complexes (ANT-C and BX-C) were identified within embryo tissue sections by in situ hybridization. These six loci belong to the Antennapedia class of the homeo box gene family. Transcripts encoded by each locus are detected primarily in discrete, nonoverlapping regions of the embryonic central nervous system (CNS). The regions of the CNS that contain transcripts encoded by each of these loci correspond to the embryonic segments that are disrupted in mutants for these genes. The maintenance of spatially restricted expression of each ANT-C and BX-C locus could involve hierarchical, cross-regulatory interactions that are mediated by the homeo box protein domains encoded by these genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harding, K -- Wedeen, C -- McGinnis, W -- Levine, M -- New York, N.Y. -- Science. 1985 Sep 20;229(4719):1236-42.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3898362" target="_blank"〉PubMed〈/a〉

    Amplification of a novel v-erbB-related gene in a human mammary carcinoma (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-09-06
    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〉

    Publication Date: 1985-10-11
    Description: The genes controlling high-level production of Shiga-like toxin (SLT) in Escherichia coli were cloned from the SLT converting phage 933J. This phage was isolated from a strain of E. coli that caused a foodborne outbreak of hemorrhagic colitis. The genes that convert normal E. coli to organisms producing high levels of toxin were cloned into the plasmid pBR328 and expressed in E. coli HB101. DNA restriction mapping, subcloning, examination of the cloned gene products by minicell analysis, neutralization, and immunoprecipitation with antibodies to SLT were used to localize the toxin converting genes and identify them as structural genes for SLT. Southern hybridization studies established that the DNA fragment carrying the cloned toxin structural genes had homology with the DNA of Shigella.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Newland, J W -- Strockbine, N A -- Miller, S F -- O'Brien, A D -- Holmes, R K -- New York, N.Y. -- Science. 1985 Oct 11;230(4722):179-81.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2994228" target="_blank"〉PubMed〈/a〉

    Description: A bovine retinal complementary DNA clone encoding the alpha subunit of transducin (T alpha) was isolated with the use of synthetic oligodeoxynucleotides as probes, and the complete nucleotide sequence of the insert was determined. THe predicted protein sequence of 354 amino acids includes the known sequences of four tryptic peptides and sequences adjacent to the residues that undergo adenosine diphosphate ribosylation by cholera toxin and pertussis toxin. On the basis of homologies to other proteins, such as the elongation factors of protein synthesis and the ras oncogene proteins, regions are identified that are predicted to be acylated and involved in guanine nucleotide binding and hydrolysis. Amino acid sequence similarity between T alpha and ras is confined to these regions of the molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lochrie, M A -- Hurley, J B -- Simon, M I -- New York, N.Y. -- Science. 1985 Apr 5;228(4695):96-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3856323" target="_blank"〉PubMed〈/a〉

    Description: The nucleotide sequence of molecular clones of DNA from a retrovirus, ARV-2, associated with the acquired immune deficiency syndrome (AIDS) was determined. Proviral DNA of ARV-2 (9737 base pairs) has long terminal repeat structures (636 base pairs) and long open reading frames encoding gag (506 codons), pol (1003 codons), and env (863 codons) genes. Two additional open reading frames were identified. Significant amino acid homology with several other retroviruses was noted in the predicted product of gag and pol, but ARV-2 was as closely related to murine and avian retroviruses as it was to human T-cell leukemia viruses (HTLV-I and HTLV-II).

    Cystic fibrosis locus defined by a genetically linked polymorphic DNA marker (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-11-29
    Description: A polymorphic DNA marker has been found genetically linked, in a set of 39 human families, to an autosomal recessive gene that causes cystic fibrosis (CF), a disease affecting one in 2000 Caucasian children. The DNA marker (called D0CRI-917) is also linked to the PON locus, which by independent evidence is linked to the CF locus. The best estimates of the genetic distances are 5 centimorgans between the DNA marker and PON and 15 centimorgans between the DNA marker and the CF locus, meaning that the location of the disease gene has been narrowed to about 1 percent of the human genome (about 30 million base pairs). Although the data are consistent with the interpretation that a single locus causes cystic fibrosis, the possibility of genetic heterogeneity remains. The discovery of a linked DNA polymorphism is the first step in molecular analysis of the CF gene and its causative role in the disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsui, L C -- Buchwald, M -- Barker, D -- Braman, J C -- Knowlton, R -- Schumm, J W -- Eiberg, H -- Mohr, J -- Kennedy, D -- Plavsic, N -- New York, N.Y. -- Science. 1985 Nov 29;230(4729):1054-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2997931" target="_blank"〉PubMed〈/a〉

    Description: Phenylketonuria (PKU) is caused by a genetic deficiency of the enzyme phenylalanine hydroxylase (PAH). A full-length complementary DNA clone of human PAH was inserted into a eukaryotic expression vector and transferred into mouse NIH3T3 cells which do not normally express PAH. The transformed mouse cells expressed PAH messenger RNA, immunoreactive protein, and enzymatic activity that are characteristic of the normal human liver products, demonstrating that a single gene contains all of the necessary genetic information to code for functional PAH. These results support the use of the human PAH probe in prenatal diagnosis and detection of carriers, to provide new opportunities for the biochemical characterization of normal and mutant enzymes, and in the investigation of alternative genetic therapies for PKU.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ledley, F D -- Grenett, H E -- DiLella, A G -- Kwok, S C -- Woo, S L -- HD-06495/HD/NICHD NIH HHS/ -- HD-17711/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1985 Apr 5;228(4695):77-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3856322" target="_blank"〉PubMed〈/a〉

    Description: The molecular size of the plasma LDL (low density lipoprotein) receptor synthesized by cultured fibroblasts from a patient with the internalization-defective form of familial hypercholesterolemia (FH 274) was smaller by 10,000 daltons than the size of the normal LDL receptor. The segment of the gene encoding the truncated portion of the FH 274 receptor was cloned into bacteriophage lambda. Comparison of the nucleotide sequences of the normal and FH 274 genes revealed a 5-kilobase deletion, which eliminated the exons encoding the membrane-spanning region and the carboxyl terminal cytoplasmic domain of the receptor. The deletion appeared to be caused by a novel intrastrand recombination between two repetitive sequences of the Alu family that were oriented in opposite directions. The truncated receptors lack membrane-spanning regions and cytoplasmic domains; they are largely secreted into the culture medium, but a small fraction remains adherent to the cell surface. The surface-adherent receptors bind LDL, but they are unable to cluster in coated pits, thus explaining the internalization-defective phenotype.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4449727/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4449727/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lehrman, M A -- Schneider, W J -- Sudhof, T C -- Brown, M S -- Goldstein, J L -- Russell, D W -- HL 01287/HL/NHLBI NIH HHS/ -- HL 20948/HL/NHLBI NIH HHS/ -- HL 31346/HL/NHLBI NIH HHS/ -- P01 HL020948/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1985 Jan 11;227(4683):140-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3155573" target="_blank"〉PubMed〈/a〉

    Structure of the human interleukin-2 receptor gene (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-11-08
    Description: The gene encoding the human interleukin-2 (IL-2) receptor consists of 8 exons spanning more than 25 kilobases on chromosome 10. Exons 2 and 4 were derived from a gene duplication event and unexpectedly also are homologous to the recognition domain of human complement factor B. Alternative messenger RNA (mRNA) splicing may delete exon 4 sequences, resulting in a mRNA that does not encode a functional IL-2 receptor. Leukemic T cells infected with HTLV-I and normal activated T cells express IL-2 receptors with identical deduced protein sequences. Receptor gene transcription is initiated at two principal sites in normal activated T cells. Adult T cell leukemia cells infected with HTLV-I show activity at both of these sites, but also at a third transcription initiation site.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leonard, W J -- Depper, J M -- Kanehisa, M -- Kronke, M -- Peffer, N J -- Svetlik, P B -- Sullivan, M -- Greene, W C -- New York, N.Y. -- Science. 1985 Nov 8;230(4726):633-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2996141" target="_blank"〉PubMed〈/a〉

    Deletion in chromosome 11p associated with a hepatitis B integration site in hepatocellular carcinoma (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-10-18
    Description: Hepatitis B virus (HBV), a virus with known carcinogenic potential, integrates into cellular DNA during long-term persistent infection in man. Hepatocellular carcinomas isolated from viral carriers often contain clonally propagated viral DNA integrations. As small chromosomal deletions are associated with several types of carcinomas, the occurrence of chromosomal deletions in association with HBV integration in hepatocellular carcinoma was studied. HBV integration was accompanied by a deletion of at least 13.5 kilobases of cellular sequences in a human hepatocellular carcinoma. The viral DNA integration and deletion of cellular sequences occurred on the short arm of chromosome 11 at location 11p13-11p14. The cellular sequences that were deleted at the site of HBV integration were lost from the tumor cells, leaving only a single copy of the remaining cellular allele.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rogler, C E -- Sherman, M -- Su, C Y -- Shafritz, D A -- Summers, J -- Shows, T B -- Henderson, A -- Kew, M -- AM17702/AM/NIADDK NIH HHS/ -- CA32605/CA/NCI NIH HHS/ -- CA37232-02/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1985 Oct 18;230(4723):319-22.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2996131" target="_blank"〉PubMed〈/a〉

    Involvement of the bcl-2 gene in human follicular lymphoma (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-06-21
    Description: Recombinant DNA probes were cloned for the areas flanking the breakpoint on chromosome 18 in cells from a patient with acute lymphocytic leukemia of the B-cell type; cells of this line carry the t(14;18) chromosomal translocation. Two of the probes detected DNA rearrangements in approximately 60 percent of the cases of follicular lymphoma screened. In follicular lymphoma, most of the breakpoints in band q21 of chromosome 18 were clustered within a short stretch of DNA, approximately 2.1 kilobases in length. Chromosome 18-specific DNA probes for the areas flanking the breakpoints also detected RNA transcripts 6 kilobases in length in various cell types. The gene coding for these transcript (the bcl-2 gene) seems to be interrupted in most cases of follicular lymphomas carrying the t(14;18) chromosomal translocation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsujimoto, Y -- Cossman, J -- Jaffe, E -- Croce, C M -- CA16685/CA/NCI NIH HHS/ -- CA36521/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1985 Jun 21;228(4706):1440-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3874430" target="_blank"〉PubMed〈/a〉

    Sequence and structure of a human glucose transporter (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-09-06
    Description: The amino acid sequence of the glucose transport protein from human HepG2 hepatoma cells was deduced from analysis of a complementary DNA clone. Structural analysis of the purified human erythrocyte glucose transporter by fast atom bombardment mapping and gas phase Edman degradation confirmed the identity of the clone and demonstrated that the HepG2 and erythrocyte transporters are highly homologous and may be identical. The protein lacks a cleavable amino-terminal signal sequence. Analysis of the primary structure suggests the presence of 12 membrane-spanning domains. Several of these may form amphipathic alpha helices and contain abundant hydroxyl and amide side chains that could participate in glucose binding or line a transmembrane pore through which the sugar moves. The amino terminus, carboxyl terminus, and a highly hydrophilic domain in the center of the protein are all predicted to lie on the cytoplasmic face. Messenger RNA species homologous to HepG2 glucose transporter messenger RNA were detected in K562 leukemic cells, HT29 colon adenocarcinoma cells, and human kidney tissue.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mueckler, M -- Caruso, C -- Baldwin, S A -- Panico, M -- Blench, I -- Morris, H R -- Allard, W J -- Lienhard, G E -- Lodish, H F -- GM22996/GM/NIGMS NIH HHS/ -- HL32262/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1985 Sep 6;229(4717):941-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3839598" target="_blank"〉PubMed〈/a〉

    Expression of the major surface antigen of Plasmodium knowlesi sporozoites in yeast (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-05-17
    Description: The circumsporozite protein, a surface antigen of the sporozoite stage of the monkey malarial parasite Plasmodium knowlesi, was expressed in the yeast Saccharomyces cerevisiae by using an expression vector containing the 5' regulatory region of the yeast alcohol dehydrogenase I gene. It was necessary to eliminate the entire 5' upstream region of the parasite DNA to obtain the expression of this protein. Only the circumsporozoite precursor was produced by the yeast transformants, as detected by immunoblotting. About 55 and 20 percent of the circumsporozoite protein produced in yeast was associated wtih the 25,000 g and 150,000 g particulate fractions, respectively. The protein could be solubilized in Triton X-100 and was stable in solubilized extracts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sharma, S -- Godson, G N -- 1 R01 AI21496-01/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1985 May 17;228(4701):879-82.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3890178" target="_blank"〉PubMed〈/a〉

    A hydrophobic transmembrane segment at the carboxyl terminus of thy-1 (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-02-08
    Description: The mode of integration of the glycoprotein thy-1 within the cell membrane has been controversial due to an apparent lack of a transmembrane hydrophobic segment. Rat and mouse complementary DNA and genomic clones encoding the thy-1 molecule have been isolated and sequenced. These studies have enabled us to determine the intron-exon organization of the thy-1 gene. Furthermore, they have revealed the existence of a sequence which would encode an extra segment (31 amino acids) at the carboxyl terminus of the thy-1 molecule. These extra amino acids include a 20-amino acid hydrophobic segment which may be responsible for integration of thy-1 within the plasma membrane.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seki, T -- Chang, H C -- Moriuchi, T -- Denome, R -- Ploegh, H -- Silver, J -- CA38404/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1985 Feb 8;227(4687):649-51.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2857501" target="_blank"〉PubMed〈/a〉
