Deferoxamine 47-62 structural maintenance of chromosomes 1A Homo sapiens 19-23 21390062-0 2011 Phosphorylation of SMC1 by ATR is required for desferrioxamine (DFO)-induced apoptosis. Deferoxamine 64-67 structural maintenance of chromosomes 1A Homo sapiens 19-23 21390062-3 2011 Here, we studied the mechanism of DNA damage checkpoint activated by ATR-SMC1 pathway when cells are treated with desferrioxamine (DFO), a hypoxia-mimetic reagent. Deferoxamine 114-129 structural maintenance of chromosomes 1A Homo sapiens 73-77 21390062-3 2011 Here, we studied the mechanism of DNA damage checkpoint activated by ATR-SMC1 pathway when cells are treated with desferrioxamine (DFO), a hypoxia-mimetic reagent. Deferoxamine 131-134 structural maintenance of chromosomes 1A Homo sapiens 73-77 21390062-4 2011 We show that DFO treatment induces phosphorylation of SMC1 at Ser966, NBS1 at Ser343, Chk1 at Ser317, Chk2 at Thr68, and p53 at Ser15. Deferoxamine 13-16 structural maintenance of chromosomes 1A Homo sapiens 54-58 21390062-5 2011 Among these sites, phosphorylation of SMC1, NBS1, and Chk1 by DFO are mediated by ATR as it is greatly reduced in both ATR-deficient human fibroblasts and HCT116 human colon cancer cells in which ATR is heterozygously mutated, whereas these proteins are phosphorylated in cells deficient for ATM and DNA-PKcs. Deferoxamine 62-65 structural maintenance of chromosomes 1A Homo sapiens 38-42 21390062-7 2011 Expression of SMC1 S966A in which Ser966 is substituted to Ala attenuates apoptosis and phosphorylation of Chk1 at Ser317 after DFO treatment, although levels of HIF1alpha are not significantly changed. Deferoxamine 128-131 structural maintenance of chromosomes 1A Homo sapiens 14-18 21390062-8 2011 These results suggest that DFO induces apoptosis through the ATR-SMC1 arm of the pathway.
