英文摘要 | In this work, our study focused on as(2)o(3) action in view point of telomere. results showed that treatment of human gastric cancer mgc803 cells with arsenic trioxide could cause up-regulation of telomeric repeat binding factor trf1 and trf2 mrna and protein levels, and induced g2/m phase arrest and cell apoptosis. at the same time, telomere length shortening and telomerase inhibitory were not obvious. flow cytometry measurements indicated that the increase of trf1 and trf2 proteins is related to oxidative stress by arsenic trioxide. results also indicate that after arsenic trioxide treatment, p53 protein levels increased significantly and also could bind directly at the telomere t-loop junction. these findings demonstrate arsenic trioxide-induced cell cycle arrest and apoptosis might involve a novel pathway related to trf1, trf2 protein.
