Abstract:
Objective To explore the anti-proliferation and apoptosis-induced effects of matrine on HT29 cell and their possible mechanism.Methods HT29 Cell proliferative activity was measured by MTT assay;Cell cycle and apoptosis were analyzed by Flow Cytometry;Alteration of cellular skeleton was observed by transmission electron microscopy(TEM);Global gene expression profiles were scanned by gene chip.Results After exposure to matrine at concentrations from 0.062 5 to 0.5 mg/mL for 48 h,cellular proliferation was inhibited with increasing the concentration,but this inhibitory effect attenuated at 1 mg/mL and the apoptosis was up-regulated significantly.G2/M and G1/S phases of cell cycle were,to some extent,arrested.Under TEM,the morphological changes could be found.Gene chip showed that matrine could alter a large number of genes,which related to the cell proliferation,cell cycle,and apoptosis.Conclusion The anti-proliferation and apoptosis-induced effects of matrine on HT29 cells are concentration-dependent through changing of many genes involved in proliferation,cell cycle,and apoptosis.
