Abstract：
BACKGROUND/AIM:AZD8055 is an inhibitor of mammalian target of rapamycin (mTOR) that can suppress both mTOR complex 1 (mTORC1) and mTORC2. This study investigated the antitumor effects of AZD8055 on colon cancer. MATERIALS AND METHODS:The effects of AZD8055 on proliferation, apoptosis, and cell cycle of colon cancer cells, and tumor growth in a mouse colon cancer model were studied. RESULTS:AZD8055 significantly inhibited proliferation and induced apoptosis of colon cancer cells (p<0.05). The phosphorylation of both AKT and S6 kinase 1 (S6K1) was suppressed by AZD8055. AZD8055 also induced G0/G1 cell-cycle arrest, reduced cyclin D1 and increased p27 expression, and suppressed the levels of phospho-cyclin-dependent kinase 2 and phospho-retinoblastoma. Compared to the control, oral administration of AZD8055 significantly suppressed tumor growth in mice (p<0.05). CONCLUSION:AZD8055 induces cytotoxicity, apoptosis, and cell-cycle arrest of colon cancer cells, and exerts an antitumor effect in mice. It also inhibits the mTOR signaling pathway and mTOR-dependent cell-cycle progression.
