Etoposide, an anticancer DNA topoisomerase II poison, plays an important role in the therapy for human cancers. Unfortunately, many cancers develop etoposide resistance and do not respond to chemotherapy, leading to difficulty in treatment and poor prognosis. In this study, we investigate the effects of HBXIP gene silencing on etoposide chemosensitivity in MCF-7 human breast cancer cells. We find...
PI3K/Akt/mTOR pathway plays an important role in tumor progression and anti-cancer drug resistance. The aim of the present study is to determine the antitumor effect of CCT128930, a novel small molecule inhibitor of Akt, in the HepG2 hepatoma cancer cells. Our results showed that at low concentrations, CCT128930 increased, but not inhibited, the phosphorylation of Akt in HepG2 and A549 cells. CCT128930...
Hepatocellular carcinoma (HCC) is a major cause of morbidity and mortality in the world. The aim of the present study is to determine the antitumor effect of PF-04691502, a potent inhibitor of PI3K and mTOR kinases, on the apoptosis and angiogenesis of the hepatoma cancer cells. Our results indicate that treatment of cancer cells with PF-04691502 reduces cell viability and inhibits cell growth in...
