Abstract

Objective : In this study, we investigated the effects of ethanol extract of Anemarrhenae Rhizoma (EAR) on the proliferation and apoptosis induction of HT-29 human colon cancer cells. Methods : Cell viability of HT-29 cells were measured by MTT assay and apoptisis-related proteins were assessed using western blotting. Chromatin condensation of HT-29 cells stained with Hoechst 33258. Results : In the present study, we demonstrated that EAR exhibited significant cytotoxicity in HT-29 cells. The induction of apoptosis in HT-29 cells by EAR treatment was characterized by chromatin condensation and the activation of caspase-3. EAR-induced apoptosis is accompanied by the release of cytochrome c and the specific proteolytic cleavage of PARP. EAR was appeared cytotoxic effect to HT-29 cells in a dose-dependent manner. Concomitantly, EAR treatment led to increase in the caspase-9. The reduction of Bcl-2 and truncation of Bid were induced by EAR. Conclusion : We studied that the EAR induced apoptosis in human colon adenocarcinoma HT-29 cells. These results indicated that EAR can cause apoptosis through mitochondria/caspase pathway in human HT-29 cells.
