Abstract | PURPOSE: METHODS: Human gastric cancer MKN-45 cells or nude mice xenografted with MKN-45 cells were treated by NVP-BEZ235 and fluorouracil (5-FU) alone or in combination. The proliferation, invasion, apoptosis, and chemoresistance of gastric cancer cells were examined in vivo and in vitro. RESULTS: In vitro, combined treatment with NVP-BEZ235 and 5-FU showed synergistic inhibitory effects on proliferation, migration, and invasion and synergistic stimulating effects on apoptosis of MKN-45 cells. In vivo, NVP-BEZ235 and 5-FU synergistically inhibited the growth and induced apoptosis of MKN-45 xenografts. Mechanistically, NVP-BEZ235 inhibited PI3K/Akt/mTOR signaling; decreased the levels of Bcl-2, MMP9, and VEGF; but increased the levels of Bax and cleaved caspase-3 in MKN-45 xenografts. CONCLUSION:
