    KAI1, a metastasis suppressor gene for prostate cancer on human chromosome 11p11.2 (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-05-12
    Description: A gene from human chromosome 11p11.2 was isolated and was shown to suppress metastasis when introduced into rat AT6.1 prostate cancer cells. Expression of this gene, designated KAI1, was reduced in human cell lines derived from metastatic prostate tumors. KAI1 specifies a protein of 267 amino acids, with four hydrophobic and presumably transmembrane domains and one large extracellular hydrophilic domain with three potential N-glycosylation sites. KAI1 is evolutionarily conserved, is expressed in many human tissues, and encodes a member of a structurally distinct family of leukocyte surface glycoproteins. Decreased expression of this gene may be involved in the malignant progression of prostate and other cancers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dong, J T -- Lamb, P W -- Rinker-Schaeffer, C W -- Vukanovic, J -- Ichikawa, T -- Isaacs, J T -- Barrett, J C -- CA 58236/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1995 May 12;268(5212):884-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Carcinogenesis, National Institute of Environmental Health Sciences, National Institute of Health, Research Triangle Park, NC 27709, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7754374" target="_blank"〉PubMed〈/a〉

    Induction of gene amplification by arsenic (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-07-01
    Description: Arsenic is a well-established carcinogen in humans, but there is little evidence for its carcinogenicity in animals and it is inactive as an initiator or tumor promoter in two-stage models of carcinogenicity in mice. Two arsenic salts (sodium arsenite and sodium arsenate) induced a high frequency of methotrexate-resistant 3T6 cells, which were shown to have amplified copies of the dihydrofolate reductase gene. The ability of arsenic to induce gene amplification may relate to its carcinogenic effects in humans since amplification of oncogenes is observed in many human tumors. The inability of arsenic to induce gene mutations may relate to the negative results of arsenic in long-term animal studies and suggests that these experiments may not detect some environmental agents that act late in the carcinogenic process in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, T C -- Tanaka, N -- Lamb, P W -- Gilmer, T M -- Barrett, J C -- New York, N.Y. -- Science. 1988 Jul 1;241(4861):79-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Carcinogenesis, National Institute of Environmental Health Sciences, Research Triangle Park, North Carolina 27709.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3388020" target="_blank"〉PubMed〈/a〉
