摘要: Topoisomerase II inhibitor ellipticine effectively suppressed the growth of human non-small-cell-lung-cancer (NSCLC) epithelial cells. Previously, we reported drug activity was consummated through parallel nucleus migration p53 and Akt in A549 While inducing cell death, proved related to autophagy phosphorylated at S473. In addition, induced cytotoxicity p53-null H1299 cells with stable expression ectopic p53. this work, further demonstrated that dominant-negative (S473A) or shRNA inhibited ellipticine-mediated translocalization attenuated apoptotic death The presence predates death, assists translocation activation pathway. Growth inhibition collaborating Akt(473) lung cancer provided a new perspective topoisomerase as an effective therapy agent.
