    Description: Germline mutations in the von Hippel-Lindau tumor suppressor gene (VHL) predispose individuals to a variety of tumors, including renal carcinoma, hemangioblastoma of the central nervous system, and pheochromocytoma. Here, a cellular transcription factor, Elongin (SIII), is identified as a functional target of the VHL protein. Elongin (SIII) is a heterotrimer consisting of a transcriptionally active subunit (A) and two regulatory subunits (B and C) that activate transcription elongation by RNA polymerase II. The VHL protein was shown to bind tightly and specifically to the Elongin B and C subunits and to inhibit Elongin (SIII) transcriptional activity in vitro. These findings reveal a potentially important transcriptional regulatory network in which the VHL protein may play a key role.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Duan, D R -- Pause, A -- Burgess, W H -- Aso, T -- Chen, D Y -- Garrett, K P -- Conaway, R C -- Conaway, J W -- Linehan, W M -- Klausner, R D -- GM41628/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1995 Sep 8;269(5229):1402-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Urologic Oncology Section, National Cancer Institute, National Institutes of Health, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7660122" target="_blank"〉PubMed〈/a〉

    Description: A candidate gene for the chromosome 1 Alzheimer's disease (AD) locus was identified (STM2). The predicted amino acid sequence for STM2 is homologous to that of the recently cloned chromosome 14 AD gene (S182). A point mutation in STM2, resulting in the substitution of an isoleucine for an asparagine (N141l), was identified in affected people from Volga German AD kindreds. This N141l mutation occurs at an amino acid residue that is conserved in human S182 and in the mouse S182 homolog. The presence of missense mutations in AD subjects in two highly similar genes strongly supports the hypothesis that mutations in both are pathogenic.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levy-Lahad, E -- Wasco, W -- Poorkaj, P -- Romano, D M -- Oshima, J -- Pettingell, W H -- Yu, C E -- Jondro, P D -- Schmidt, S D -- Wang, K -- AG0513C/AG/NIA NIH HHS/ -- R01-AG11762/AG/NIA NIH HHS/ -- R01-AG11899/AG/NIA NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1995 Aug 18;269(5226):973-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Geriatric Research Education, and Clinical Center (182B), Veterans Affairs Medical Center, Seattle, WA 98108, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7638622" target="_blank"〉PubMed〈/a〉

    Description: An approach for genome analysis based on sequencing and assembly of unselected pieces of DNA from the whole chromosome has been applied to obtain the complete nucleotide sequence (1,830,137 base pairs) of the genome from the bacterium Haemophilus influenzae Rd. This approach eliminates the need for initial mapping efforts and is therefore applicable to the vast array of microbial species for which genome maps are unavailable. The H. influenzae Rd genome sequence (Genome Sequence DataBase accession number L42023) represents the only complete genome sequence from a free-living organism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fleischmann, R D -- Adams, M D -- White, O -- Clayton, R A -- Kirkness, E F -- Kerlavage, A R -- Bult, C J -- Tomb, J F -- Dougherty, B A -- Merrick, J M -- New York, N.Y. -- Science. 1995 Jul 28;269(5223):496-512.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Johns Hopkins University School of Medicine, Baltimore, MD 21205, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7542800" target="_blank"〉PubMed〈/a〉

    Description: Eukaryotic chromosomes are capped with repetitive telomere sequences that protect the ends from damage and rearrangements. Telomere repeats are synthesized by telomerase, a ribonucleic acid (RNA)-protein complex. Here, the cloning of the RNA component of human telomerase, termed hTR, is described. The template region of hTR encompasses 11 nucleotides (5'-CUAACCCUAAC) complementary to the human telomere sequence (TTAGGG)n. Germline tissues and tumor cell lines expressed more hTR than normal somatic cells and tissues, which have no detectable telomerase activity. Human cell lines that expressed hTR mutated in the template region generated the predicted mutant telomerase activity. HeLa cells transfected with an antisense hTR lost telomeric DNA and began to die after 23 to 26 doublings. Thus, human telomerase is a critical enzyme for the long-term proliferation of immortal tumor cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feng, J -- Funk, W D -- Wang, S S -- Weinrich, S L -- Avilion, A A -- Chiu, C P -- Adams, R R -- Chang, E -- Allsopp, R C -- Yu, J -- AG09383/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 1995 Sep 1;269(5228):1236-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Geron Corporation, Menlo Park, CA 94025, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7544491" target="_blank"〉PubMed〈/a〉

    Description: Basic helix-loop-helix (bHLH) proteins are instrumental in determining cell type during development. A bHLH protein, termed NeuroD, for neurogenic differentiation, has now been identified as a differentiation factor for neurogenesis because (i) it is expressed transiently in a subset of neurons in the central and peripheral nervous systems at the time of their terminal differentiation into mature neurons and (ii) ectopic expression of neuroD in Xenopus embryos causes premature differentiation of neuronal precursors. Furthermore, neuroD can convert presumptive epidermal cells into neurons and also act as a neuronal determination gene. However, unlike another previously identified proneural gene (XASH-3), neuroD seems competent to bypass the normal inhibitory influences that usually prevent neurogenesis in ventral and lateral ectoderm and is capable of converting most of the embryonic ectoderm into neurons. The data suggest that neuroD may participate in the terminal differentiation step during vertebrate neuronal development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, J E -- Hollenberg, S M -- Snider, L -- Turner, D L -- Lipnick, N -- Weintraub, H -- New York, N.Y. -- Science. 1995 May 12;268(5212):836-44.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Fred Hutchinson Cancer Research Center, Seattle, WA 98104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7754368" target="_blank"〉PubMed〈/a〉

    Description: Infection of cattle with the protozoan parasite Theileria parva results in a fatal lymphoproliferative syndrome that is associated with the overexpression of casein kinase II. The role of this enzyme in the pathogenesis of lymphoproliferative disorders was investigated by expressing the catalytic subunit in lymphocytes of transgenic mice. Adult transgenic mice displayed a stochastic propensity to develop lymphoma; co-expression of a c-myc transgene in addition to casein kinase II resulted in neonatal leukemia. Thus, the casein kinase II gene can serve as an oncogene, and its dysregulated expression is capable of transforming lymphocytes in a two-step pathway with c-myc.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seldin, D C -- Leder, P -- 1-K08-HL0286-01/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1995 Feb 10;267(5199):894-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Harvard Medical School, Howard Hughes Medical Institute, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7846532" target="_blank"〉PubMed〈/a〉

    Description: Genes from Drosophila melanogaster have been identified that encode proteins homologous to Orc2p and Orc5p of the Saccharomyces cerevisiae origin recognition complex (ORC). The abundance of the Drosophila Orc2p homolog DmORC2 is developmentally regulated and is greatest during the earliest stages of embryogenesis, concomitant with the highest rate of DNA replication. Fractionation of embryo nuclear extracts revealed that DmORC2 is found in a tightly associated complex with five additional polypeptides, much like the yeast ORC. These studies will enable direct testing of the initiator-based model of replication in a metazoan.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gossen, M -- Pak, D T -- Hansen, S K -- Acharya, J K -- Botchan, M R -- CA30490/CA/NCI NIH HHS/ -- ES-01896/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 1995 Dec 8;270(5242):1674-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cell Biology, University of California, Berkeley 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7502079" target="_blank"〉PubMed〈/a〉

    Description: Before the fusion of synaptic vesicles with the plasma membrane, a protein complex is thought to form between VAMP--an integral membrane protein of the vesicle--and two proteins associated with the plasma membrane, SNAP-25 and syntaxin. The yeast two-hybrid interaction cloning system has now been used to identify additional proteins from Aplysia that interact directly with VAMP. A 33-kilodalton membrane protein, termed VAP-33 (VAMP-associated protein of 33 kilodaltons), was identified whose corresponding messenger RNA was detected only in the central nervous system and the gill of Aplysia. Presynaptic injection of antibodies specific for VAP-33 inhibited synaptic transmission, which suggests that VAP-33 is required for the exocytosis of neurotransmitter.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Skehel, P A -- Martin, K C -- Kandel, E R -- Bartsch, D -- R37 MH45923-06/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1995 Sep 15;269(5230):1580-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, College of Physicians and Surgeons of Columbia University, New York, NY 10032, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7667638" target="_blank"〉PubMed〈/a〉

    Description: A mutated cyclin-dependent kinase 4 (CDK4) was identified as a tumor-specific antigen recognized by HLA-A2. 1-restricted autologous cytolytic T lymphocytes (CTLs) in a human melanoma. The mutated CDK4 allele was present in autologous cultured melanoma cells and metastasis tissue, but not in the patient's lymphocytes. The mutation, an arginine-to-cysteine exchange at residue 24, was part of the CDK4 peptide recognized by CTLs and prevented binding of the CDK4 inhibitor p16INK4a, but not of p21 or of p27KIP1. The same mutation was found in one additional melanoma among 28 melanomas analyzed. These results suggest that mutation of CDK4 can create a tumor-specific antigen and can disrupt the cell-cycle regulation exerted by the tumor suppressor p16INK4a.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wolfel, T -- Hauer, M -- Schneider, J -- Serrano, M -- Wolfel, C -- Klehmann-Hieb, E -- De Plaen, E -- Hankeln, T -- Meyer zum Buschenfelde, K H -- Beach, D -- New York, N.Y. -- Science. 1995 Sep 1;269(5228):1281-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medizinische Klinik und Poliklinik, Johannes Gutenberg-Universitat, Mainz, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7652577" target="_blank"〉PubMed〈/a〉

    Description: Transcriptional silencing at the HMRa locus of Saccharomyces cerevisiae requires the function of the origin recognition complex (ORC), the replication initiator of yeast. Expression of a Drosophila melanogaster Orc2 complementary DNA in the yeast orc2-1 strain, which is defective for replication and silencing, complemented the silencing defect but not the replication defect; this result indicated that the replication and silencing functions of ORC were separable. The orc2-1 mutation mapped to the region of greatest homology between the Drosophila and yeast proteins. The silent state mediated by DmOrc2 was epigenetic; it was propagated during mitotic divisions in a relatively stable way, whereas the nonsilent state was metastable. In contrast, the silent state was erased during meiosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ehrenhofer-Murray, A E -- Gossen, M -- Pak, D T -- Botchan, M R -- Rine, J -- GM31105/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1995 Dec 8;270(5242):1671-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cell Biology, University of California, Berkeley 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7502078" target="_blank"〉PubMed〈/a〉
