title: Pro-apoptotic and microtubule-disassembly effects of ardisiacrispin (A+B), triterpenoid saponins from Ardisia crenata on human hepatoma Bel-7402 cells.
abstract: Ardisiacrispin (A+B) is a mixture of ardisiacrispins A and B, derived from Ardisia crenata with a fixed proportion (2:1). The present study was conducted to investigate its anticancer activity on human cancer cells and its underlying mechanism of action. The (IC50)s of ardisiacrispin (A+B) on proliferation of several human cancer cell lines were in the range of 0.9-6.5 microg/ml by sulphorhodamine B-based colorimetric assay, in which Bel-7402 was the most sensitive cell line. Moreover, ardisiacrispin (A+B) induced dose-dependent apoptosis in Bel-7402 cells at doses of 1-10 microg/ml by flow cytometry, and resulted in the changes of the mitochondrial membrane depolarization, membrane permeability enhancement, and nuclear condensation in a dose-dependent manner through high-content screening analysis. Furthermore, ardisiacrispin (A+B) could disassemble microtubule in Bel-7402 cells; the fluorescence intensity of microtubules decreased at the concentration of 5-20 microg/ml. These findings suggest that ardisiacrispin (A+B) could inhibit the proliferation of Bel-7402 cells by inducing apoptosis and disassembling microtubule.
