Abstract
AIM: To study the effect of caffeic acid phenethyl ester (CAPE) on proliferation, cell cycle, apoptosis in the cultured colorectal cancer cell line HCT116.
METHODS: HCT116 cells were treated with CAPE at serial concentrations of 80, 40, 20, 10, 5, and 2.5 mg/L. The proliferative status of HCT116 cells was measured by using methabenzthiazuron (MTT) assay. Cell cycle was analyzed by using flow cytometry (FCM) with propidium iodide (PI) labeling method. The rate of apoptosis was detected by using FCM with Annexin V-FITC and PI double labeling method.
RESULTS: After HCT116 cells were exposed to CAPE (80, 40, 20, 10, 5 and 2.5 mg/L) for 24, 48, 72 and 96 h, CAPE displayed a strong growth inhibitory effect on HCT116 cells in a dose-and time-dependent manner. FCM analysis showed that G0 /G1 phase rate increased, S phase rate decreased and apoptosis rate increased after HCT116 cells were exposed to CAPE (10, 5, and 2.5 mg/L) for 24 h, which were positively related to the concentration of CAPE.
CONCLUSION: CAPE can inhibit the proliferation of human colorectal cancer cell line HCT116, which is related to the cell cycle arrest and apoptosis.
