    Two G protein oncogenes in human endocrine tumors (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-08-10
    Description: Somatic mutations in a subset of growth hormone (GH)-secreting pituitary tumors convert the gene for the alpha polypeptide chain (alpha s) of Gs into a putative oncogene, termed gsp. These mutations, which activate alpha s by inhibiting its guanosine triphosphatase (GTPase) activity, are found in codons for either of two amino acids, each of which is completely conserved in all known G protein alpha chains. The likelihood that similar mutations would activate other G proteins prompted a survey of human tumors for mutations that replace either of these two amino acids in other G protein alpha chain genes. The first gene so far tested, which encodes the alpha chain of Gi2, showed mutations that replaced arginine-179 with either cysteine or histidine in 3 of 11 tumors of the adrenal cortex and 3 of 10 endocrine tumors of the ovary. The mutant alpha i2 gene is a putative oncogene, referred to as gip2. In addition, gsp mutations were found in 18 of 42 GH-secreting pituitary tumors and in an autonomously functioning thyroid adenoma. These findings suggest that human tumors may harbor oncogenic mutations in various G protein alpha chain genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lyons, J -- Landis, C A -- Harsh, G -- Vallar, L -- Grunewald, K -- Feichtinger, H -- Duh, Q Y -- Clark, O H -- Kawasaki, E -- Bourne, H R -- New York, N.Y. -- Science. 1990 Aug 10;249(4969):655-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Human Genetics, Cetus Corporation, Emeryville CA 94608.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2116665" target="_blank"〉PubMed〈/a〉

    Identification of p53 gene mutations in bladder cancers and urine samples (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-05-03
    Description: Although bladder cancers are very common, little is known about their molecular pathogenesis. In this study, invasive bladder cancers were evaluated for the presence of gene mutations in the p53 suppressor gene. Of 18 tumors evaluated, 11 (61 percent) were found to have genetic alterations of p53. The alterations included ten point mutations resulting in single amino acid substitutions, and one 24-base pair deletion. In all but one case, the mutations were associated with chromosome 17p allelic deletions, leaving the cells with only mutant forms of the p53 gene products. Through the use of the polymerase chain reaction and oligomer-specific hybridization, p53 mutations were identified in 1 to 7 percent of the cells within the urine sediment of each of three patients tested. The p53 mutations are the first genetic alterations demonstrated to occur in a high proportion of primary invasive bladder cancers. Detection of such mutations ex vivo has clinical implications for monitoring individuals whose tumor cells are shed extracorporeally.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sidransky, D -- Von Eschenbach, A -- Tsai, Y C -- Jones, P -- Summerhayes, I -- Marshall, F -- Paul, M -- Green, P -- Hamilton, S R -- Frost, P -- CA09071/CA/NCI NIH HHS/ -- CA43460/CA/NCI NIH HHS/ -- CA49758/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1991 May 3;252(5006):706-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Oncology, Johns Hopkins University, Baltimore, MD 21231.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2024123" target="_blank"〉PubMed〈/a〉

    Identification of a chromosome 18q gene that is altered in colorectal cancers (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-01-05
    Description: Allelic deletions involving chromosome 18q occur in more than 70 percent of colorectal cancers. Such deletions are thought to signal the existence of a tumor suppressor gene in the affected region, but until now a candidate suppressor gene on this chromosomal arm had not been identified. A contiguous stretch of DNA comprising 370 kilobase pairs (kb) has now been cloned from a region of chromosome 18q suspected to reside near this gene. Potential exons in the 370-kb region were defined by human-rodent sequence identities, and the expression of potential exons was assessed by an "exon-connection" strategy based on the polymerase chain reaction. Expressed exons were used as probes for cDNA screening to obtain clones that encoded a portion of a gene termed DCC; this cDNA was encoded by at least eight exons within the 370-kb genomic region. The predicted amino acid sequence of the cDNA specified a protein with sequence similarity to neural cell adhesion molecules and other related cell surface glycoproteins. While the DCC gene was expressed in most normal tissues, including colonic mucosa, its expression was greatly reduced or absent in most colorectal carcinomas tested. Somatic mutations within the DCC gene observed in colorectal cancers included a homozygous deletion of the 5' end of the gene, a point mutation within one of the introns, and ten examples of DNA insertions within a 0.17-kb fragment immediately downstream of one of the exons. The DCC gene may play a role in the pathogenesis of human colorectal neoplasia, perhaps through alteration of the normal cell-cell interactions controlling growth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fearon, E R -- Cho, K R -- Nigro, J M -- Kern, S E -- Simons, J W -- Ruppert, J M -- Hamilton, S R -- Preisinger, A C -- Thomas, G -- Kinzler, K W -- CA 09243/CA/NCI NIH HHS/ -- GM07184/GM/NIGMS NIH HHS/ -- GM07309/GM/NIGMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1990 Jan 5;247(4938):49-56.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Oncology Center, Johns Hopkins University School of Medicine, Baltimore, MD 21231.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2294591" target="_blank"〉PubMed〈/a〉

    Identification of a gene located at chromosome 5q21 that is mutated in colorectal cancers (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-03-15
    Description: Recent studies have suggested the existence of a tumor suppressor gene located at chromosome region 5q21. DNA probes from this region were used to study a panel of sporadic colorectal carcinomas. One of these probes, cosmid 5.71, detected a somatically rearranged restriction fragment in the DNA from a single tumor. Further analysis of the 5.71 cosmid revealed two regions that were highly conserved in rodent DNA. These sequences were used to identify a gene, MCC (mutated in colorectal cancer), which encodes an 829-amino acid protein with a short region of similarity to the G protein-coupled m3 muscarinic acetylcholine receptor. The rearrangement in the tumor disrupted the coding region of the MCC gene. Moreover, two colorectal tumors were found with somatically acquired point mutations in MCC that resulted in amino acid substitutions. MCC is thus a candidate for the putative colorectal tumor suppressor gene located at 5q21. Further studies will be required to determine whether the gene is mutated in other sporadic tumors or in the germ line of patients with an inherited predisposition to colonic tumorigenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kinzler, K W -- Nilbert, M C -- Vogelstein, B -- Bryan, T M -- Levy, D B -- Smith, K J -- Preisinger, A C -- Hamilton, S R -- Hedge, P -- Markham, A -- 6M 07184/PHS HHS/ -- CA 06973/CA/NCI NIH HHS/ -- CA 09243/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1991 Mar 15;251(4999):1366-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Genetics Laboratory, Johns Hopkins Oncology Center, Baltimore, MD 21231.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1848370" target="_blank"〉PubMed〈/a〉

    Isolation of sequences that span the fragile X and identification of a fragile X-related CpG island (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-03-08
    Description: Yeast artificial chromosomes (YACs) were obtained from a 550-kilobase region that contains three probes previously mapped as very close to the locus of the fragile X syndrome. These YACs spanned the fragile site in Xq27.3 as shown by fluorescent in situ hybridization. An internal 200-kilobase segment contained four chromosomal breakpoints generated by induction of fragile X expression. A single CpG island was identified in the cloned region between markers DXS463 and DXS465 that appears methylated in mentally retarded fragile X males, but not in nonexpressing male carriers of the mutation nor in normal males. This CpG island may indicate the presence of a gene involved in the clinical phenotype of the syndrome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heitz, D -- Rousseau, F -- Devys, D -- Saccone, S -- Abderrahim, H -- Le Paslier, D -- Cohen, D -- Vincent, A -- Toniolo, D -- Della Valle, G -- New York, N.Y. -- Science. 1991 Mar 8;251(4998):1236-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire de Genetique Moleculaire des Eucaryotes du CNRS, Institut de Chimie Biologique, Faculte de Medecine, Strasbourg, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2006411" target="_blank"〉PubMed〈/a〉

    Lack of protective immunity against reinfection with hepatitis C virus (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-10-02
    Description: Some individuals infected with hepatitis C virus (HCV) experience multiple episodes of acute hepatitis. It is unclear whether these episodes are due to reinfection with HCV or to reactivation of the original virus infection. Markers of viral replication and host immunity were studied in five chimpanzees sequentially inoculated over a period of 3 years with different HCV strains of proven infectivity. Each rechallenge of a convalescent chimpanzee with the same or a different HCV strain resulted in the reappearance of viremia, which was due to infection with the subsequent challenge virus. The evidence indicates that HCV infection does not elicit protective immunity against reinfection with homologous or heterologous strains, which raises concerns for the development of effective vaccines against HCV.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Farci, P -- Alter, H J -- Govindarajan, S -- Wong, D C -- Engle, R -- Lesniewski, R R -- Mushahwar, I K -- Desai, S M -- Miller, R H -- Ogata, N -- New York, N.Y. -- Science. 1992 Oct 2;258(5079):135-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Hepatitis Viruses Section, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1279801" target="_blank"〉PubMed〈/a〉

    Germ line p53 mutations in a familial syndrome of breast cancer, sarcomas, and other neoplasms (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-12-10
    Description: Familial cancer syndromes have helped to define the role of tumor suppressor genes in the development of cancer. The dominantly inherited Li-Fraumeni syndrome (LFS) is of particular interest because of the diversity of childhood and adult tumors that occur in affected individuals. The rarity and high mortality of LFS precluded formal linkage analysis. The alternative approach was to select the most plausible candidate gene. The tumor suppressor gene, p53, was studied because of previous indications that this gene is inactivated in the sporadic (nonfamilial) forms of most cancers that are associated with LFS. Germ line p53 mutations have been detected in all five LFS families analyzed. These mutations do not produce amounts of mutant p53 protein expected to exert a trans-dominant loss of function effect on wild-type p53 protein. The frequency of germ line p53 mutations can now be examined in additional families with LFS, and in other cancer patients and families with clinical features that might be attributed to the mutation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Malkin, D -- Li, F P -- Strong, L C -- Fraumeni, J F Jr -- Nelson, C E -- Kim, D H -- Kassel, J -- Gryka, M A -- Bischoff, F Z -- Tainsky, M A -- 34936/PHS HHS/ -- 5-T32-CA09299/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1990 Nov 30;250(4985):1233-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Molecular Genetics, Massachusetts General Hospital Cancer Center, Charlestown 02129.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1978757" target="_blank"〉PubMed〈/a〉

    Complementary DNA sequencing: expressed sequence tags and human genome project (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-06-21
    Description: Automated partial DNA sequencing was conducted on more than 600 randomly selected human brain complementary DNA (cDNA) clones to generate expressed sequence tags (ESTs). ESTs have applications in the discovery of new human genes, mapping of the human genome, and identification of coding regions in genomic sequences. Of the sequences generated, 337 represent new genes, including 48 with significant similarity to genes from other organisms, such as a yeast RNA polymerase II subunit; Drosophila kinesin, Notch, and Enhancer of split; and a murine tyrosine kinase receptor. Forty-six ESTs were mapped to chromosomes after amplification by the polymerase chain reaction. This fast approach to cDNA characterization will facilitate the tagging of most human genes in a few years at a fraction of the cost of complete genomic sequencing, provide new genetic markers, and serve as a resource in diverse biological research fields.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Adams, M D -- Kelley, J M -- Gocayne, J D -- Dubnick, M -- Polymeropoulos, M H -- Xiao, H -- Merril, C R -- Wu, A -- Olde, B -- Moreno, R F -- New York, N.Y. -- Science. 1991 Jun 21;252(5013):1651-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Receptor Biochemistry and Molecular Biology, National Institute of Neurological Disorders and Stroke, National Institutes of Health, Bethesda, MD.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2047873" target="_blank"〉PubMed〈/a〉

    Myotonic dystrophy mutation: an unstable CTG repeat in the 3' untranslated region of the gene (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-03-06
    Description: Myotonic dystrophy (DM) is the most common inherited neuromuscular disease in adults, with a global incidence of 1 in 8000 individuals. DM is an autosomal dominant, multisystemic disorder characterized primarily by myotonia and progressive muscle weakness. Genomic and complementary DNA probes that map to a 10-kilobase Eco RI genomic fragment from human chromosome 19q13.3 have been used to detect a variable length polymorphism in individuals with DM. Increases in the size of the allele in patients with DM are now shown to be due to an increased number of trinucleotide CTG repeats in the 3' untranslated region of a DM candidate gene. An increase in the severity of the disease in successive generations (genetic anticipation) is accompanied by an increase in the number of trinucleotide repeats. Nearly all cases of DM (98 percent or 253 of 258 individuals) displayed expansion of the CTG repeat region. These results suggest that DM is primarily caused by mutations that generate an amplification of a specific CTG repeat.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mahadevan, M -- Tsilfidis, C -- Sabourin, L -- Shutler, G -- Amemiya, C -- Jansen, G -- Neville, C -- Narang, M -- Barcelo, J -- O'Hoy, K -- New York, N.Y. -- Science. 1992 Mar 6;255(5049):1253-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, University of Ottawa, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1546325" target="_blank"〉PubMed〈/a〉

    Identification of FAP locus genes from chromosome 5q21 (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-08-09
    Description: Recent studies suggest that one or more genes on chromosome 5q21 are important for the development of colorectal cancers, particularly those associated with familial adenomatous polyposis (FAP). To facilitate the identification of genes from this locus, a portion of the region that is tightly linked to FAP was cloned. Six contiguous stretches of sequence (contigs) containing approximately 5.5 Mb of DNA were isolated. Subclones from these contigs were used to identify and position six genes, all of which were expressed in normal colonic mucosa. Two of these genes (APC and MCC) are likely to contribute to colorectal tumorigenesis. The MCC gene had previously been identified by virtue of its mutation in human colorectal tumors. The APC gene was identified in a contig initiated from the MCC gene and was found to encode an unusually large protein. These two closely spaced genes encode proteins predicted to contain coiled-coil regions. Both genes were also expressed in a wide variety of tissues. Further studies of MCC and APC and their potential interaction should prove useful for understanding colorectal neoplasia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kinzler, K W -- Nilbert, M C -- Su, L K -- Vogelstein, B -- Bryan, T M -- Levy, D B -- Smith, K J -- Preisinger, A C -- Hedge, P -- McKechnie, D -- CA06973/CA/NCI NIH HHS/ -- CA35494/CA/NCI NIH HHS/ -- CA44688/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1991 Aug 9;253(5020):661-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Genetics Laboratory, Johns Hopkins University School of Medicine, Baltimore, MD 21231.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1651562" target="_blank"〉PubMed〈/a〉
