Abstract :

Sorbus rufopilosa, a tsema rowan, is a species of the small ornamental trees in the genus Sorbus and the family Rosaceae found in East Asia. The antioxidant and anticancer effects of S. rufopilosa remain unclear. The objective of this study is to evaluate the antioxidant and anticancer effects of ethanol extract of S. rufopilosa (EESR) and the molecular mechanism of its anticancer activity in human colon carcinoma HT29 cells. EESR showed significant antioxidant activity and inhibitory effect on HT29 cell growth in a dose-dependent manner. EESR induced cell cycle arrest at G2/M phase in a dose-dependent manner by modulating the expression of cyclin B, cyclin-dependent kinase 1 (CDK1), and CDK inhibitor p21. EESR-induced apoptosis was associated with the upregulation of p53, a death receptor Fas, a pro-apoptotic protein Bax and the activation of caspase 3, 8, and 9, resulting in the degradation of poly ADP ribose polymerase (PARP). These results suggest that EESR efficiently inhibits proliferation of HT29 by inducing both cell cycle arrest and apoptosis, and may be a possible candidate for the anticancer drug development.
