ABSTRACT
We studied the anti-tumor effect of fangchinoline (FAN) against human colorectal cancer cell lines CCL-244 and SW480 and analyzed the mechanism of FAN action. The cell viability and apoptosis were assessed by MTT test and Annexin V-PI staining; caspase-3 activity was measured by Western blotting. The expression of endoplasmic reticulum stress-related proteins was assessed by real-time PCR, Western blotting, and gene transfection. It was found that FAN inhibited cell growth and induced apoptosis in human colorectal cancer cell lines CCL-244 and SW480 in a dose-dependent manner. The caspase-3 inhibitor Ac-DEVD-CHO could reverse the inhibitory effect of FAN. Moreover, FAN significantly increased the expression of endoplasmic reticulum stress-related proteins p-PERK, p-eIF2α, ATF4, and CHOP in CCL-244 and SW480 cells. In addition, endoplasmic reticulum stress inhibitor 4-phenylbutyric acid or CHOP knockdown could prevent FAN-induced apoptosis. Thus, FAN induced apoptosis of human colorectal cancer through activation of endoplasmic reticulum stress.
