AIM To investigate the effect of trichosantin （TCS） on the growth inhibition and adhesion as well as migration of SW-620 cells. METHODS The antiproliferative effect of TCS on SW-620 cell line was measured with MT＇F. The apoptosis of SW-620 cell line was detected by fluorescence staining with hochest33258. The FCM analysis was carried out to examine the effect of TCS on the cycle and apoptosis distribution of SW-620 cell line. The changes in adhesion and migration abilities of SW-620 cell were examined by using cell adhesion assay and wound healing assay, respectively. RESULTS 1. The proliferation of SW-620 cell line was significantly inhibited by TCS in a dose-and time-dependent manner; 2. TCS led a S-phase arrest in cell cycle and induced cell apoptosis. 3. TCS changed the adhesion and migration abilities of SW-620 cell. CONCLUSION The results show that TCS could inhibit the growth of SW-620 and induce cell apoptosis, and change the adherence and migration capacities of SW-620 cell line.
