    Description: Human T-cell leukemia virus has been linked with adult T-cell leukemia-lymphoma (ATLL), a tumor of mature T cells that occurs at elevated rates in southwestern Japan and in the Caribbean Basin. Human T-cell leukemia virus (HTLV) or a closely related virus, has also been found in varying proportions of healthy individuals of several species of Old World monkeys. In the present study, conducted with macaques from Taiwan and the New England Regional Primate Research Center, antibodies to membrane antigens of HTLV-infected cells (HTLV-MA) were found in 11 of 13 macaques with malignant lymphoma or lymphoproliferative disease but in only 7 of 95 of healthy macaques. This indicates that antibodies to HTLV are significantly associated with the development of naturally occurring lymphoid neoplasms in at least some species of nonhuman primates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Homma, T -- Kanki, P J -- King, N W Jr -- Hunt, R D -- O'Connell, M J -- Letvin, N L -- Daniel, M D -- Desrosiers, R C -- Yang, C S -- Essex, M -- 5TRRR07000/RR/NCRR NIH HHS/ -- CA 18216/CA/NCI NIH HHS/ -- RR00168/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1984 Aug 17;225(4663):716-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6087453" target="_blank"〉PubMed〈/a〉

    Notes: Abstract A checkpoint responding to DNA damage in G2 results in a delay in the onset of mitosis through inhibition of p34cdc2 kinase activity via maintenance of inhibitory tyrosine phosphorylation. Genetic analyses of this checkpoint in fission yeast have identified single alleles of several genes, suggesting these screens are not yet saturating, and hence further genes await identification. To fully understand the complexity of this checkpoint it will be necessary to define all the genes involved. To this end we screened for new mutants defective in the ability to delay mitosis in the presence of DNA-damaging agents. Twenty-four mutants were isolated that were defective in UV-C and MMS-induced checkpoint delay. Amongst these mutants was an allele of cut5 that was also defective in the checkpoint responses. We show here, contrary to previous reports, that the UV-C induced checkpoint response is defective in cut5 mutants. Therefore, like all other checkpoint mutants, cut5 is required for G2 checkpoint arrest following DNA damage, regardless of the nature of the lesions involved.
