Abstract
Centella asiatica is traditionally a medicinal plant frequently employed in the practice of Thai folk medicine. This study examined the anti-tumor activity of the crude water extract of C. asiatica using human colon adenocarcinoma-derived Caco-2 cells. C. asiatica extract reduced the proliferation rate of Caco-2 cells significantly in a concentration- and time-dependent manner. The mechanism of cancer cell growth inhibition was shown to occur via cell cycle arrest. The extract induced S and G2-M arrest in Caco-2 cells accompanied apoptosis induction. The extract also increased the accumulation of cyclin B1 protein in the cells. These findings indicate that C. asiatica extract inhibited cell proliferation of Caco-2 cells through modification of the cell cycle events and this cell cycle arrest is associated, at least in part, with increased accumulation of cyclin B1 protein.
