    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〉

    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〉

    Description: Human immunodeficiency virus type 1 (HIV-1) transmission from infected patients to health-care workers has been well documented, but transmission from an infected health-care worker to a patient has not been reported. After identification of an acquired immunodeficiency syndrome (AIDS) patient who had no known risk factors for HIV infection but who had undergone an invasive procedure performed by a dentist with AIDS, six other patients of this dentist were found to be HIV-infected. Molecular biologic studies were conducted to complement the epidemiologic investigation. Portions of the HIV proviral envelope gene from each of the seven patients, the dentist, and 35 HIV-infected persons from the local geographic area were amplified by polymerase chain reaction and sequenced. Three separate comparative genetic analyses--genetic distance measurements, phylogenetic tree analysis, and amino acid signature pattern analysis--showed that the viruses from the dentist and five dental patients were closely related. These data, together with the epidemiologic investigation, indicated that these patients became infected with HIV while receiving care from a dentist with AIDS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ou, C Y -- Ciesielski, C A -- Myers, G -- Bandea, C I -- Luo, C C -- Korber, B T -- Mullins, J I -- Schochetman, G -- Berkelman, R L -- Economou, A N -- New York, N.Y. -- Science. 1992 May 22;256(5060):1165-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of HIV/AIDS, Centers for Disease Control, Atlanta, GA 30333.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1589796" target="_blank"〉PubMed〈/a〉

    Description: Described here are neural networks capable of predicting a drug's mechanism of action from its pattern of activity against a panel of 60 malignant cell lines in the National Cancer Institute's drug screening program. Given six possible classes of mechanism, the network misses the correct category for only 12 out of 141 agents (8.5 percent), whereas linear discriminant analysis, a standard statistical technique, misses 20 out of 141 (14.2 percent). The success of the neural net indicates several things. (i) The cell line response patterns are rich in information about mechanism. (ii) Appropriately designed neural networks can make effective use of that information. (iii) Trained networks can be used to classify prospectively the more than 10,000 agents per year tested by the screening program. Related networks, in combination with classical statistical tools, will help in a variety of ways to move new anticancer agents through the pipeline from in vitro studies to clinical application.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weinstein, J N -- Kohn, K W -- Grever, M R -- Viswanadhan, V N -- Rubinstein, L V -- Monks, A P -- Scudiero, D A -- Welch, L -- Koutsoukos, A D -- Chiausa, A J -- New York, N.Y. -- Science. 1992 Oct 16;258(5081):447-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Mathematical Biology, National Cancer Institute, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1411538" target="_blank"〉PubMed〈/a〉

    Description: Interleukin-1 beta (IL-1 beta) mediates a wide range of immune and inflammatory responses. The active cytokine is generated by proteolytic cleavage of an inactive precursor. A complementary DNA encoding a protease that carries out this cleavage has been cloned. Recombinant expression in COS-7 cells enabled the cells to process precursor IL-1 beta to the mature form. Sequence analysis indicated that the enzyme itself may undergo proteolytic processing. The gene encoding the protease was mapped to chromosomal band 11q23, a site frequently involved in rearrangement in human cancers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cerretti, D P -- Kozlosky, C J -- Mosley, B -- Nelson, N -- Van Ness, K -- Greenstreet, T A -- March, C J -- Kronheim, S R -- Druck, T -- Cannizzaro, L A -- New York, N.Y. -- Science. 1992 Apr 3;256(5053):97-100.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Immunex Corporation, Seattle, WA 98101.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1373520" target="_blank"〉PubMed〈/a〉
