摘要: Abstract Curcumin possesses an anticancer effect against a wide assortment of tumors with selective cytotoxicity for tumor cells. However, the mechanism involved in curcumin‑induced remain unclear. In present study, we investigated efficacy curcumin human gastric cancer cell growth and molecular involved. Our results demonstrated that inhibited viabilities lines BGC-823, SGC-7901 MKN-28 both time- and dose-dependent manner. addition, treatment induced apoptosis dose‑responsive Western blotting apoptosis‑related proteins further confirmed pro-apoptotic potential curcumin. After exposure to curcumin, robust induction autophagy was observed cells, which characterized by formation acidic vesicular organelles (AVOs), conversion LC3-I LC3-II increase levels autophagy‑related proteins. Activation PI3K/Akt/mTOR signaling pathway suppressed cells treatment. administration inhibitor 3-methyladenine (3-MA) significantly promoted apoptotic death Collectively, our findings provide new evidence induces protective in vitro. Autophagy may novel effective strategy improving cancer.
