Purpose : This study was aimed to investigate the inhibitory effect of Millettia Reticulatas on the proliferation of human uterine leiomyoma cells and the expression of gene related the mechanism of cell apoptosis.
Methods : We counted the number of death cells treated with indicated concentration of Millettia Reticulatas and investigated cell death rate by MTS assay. Furthermore, flow cytometry analyis and DNA fragmentation assay were used to dissect between necrosis and apoptosis. and then we observed the differential gene expression by western blot analysis.
Results : 1) The inhibitory effect on the growth of uterine leiomyoma cell treated with Millettia Reticulatas was increased in a concentration proportional. 2) The result of flow cytometry analysis. subG1 phase arrest related3 cell apoptosis was investigated 23.49% in uterine leiomyoma cell treated Millettia Reticulatas and showed the fession of proportional concentration. 3) The gene expression of p27, p53, p21, p16 related cell cycle was increased according to increasing concentration but cyclin E was none exchanged. 4) The character of apoptosis, DNA fragmentation was significantly observed the fession of proportional concentration. 5) The expression of pro-caspase3 and PARP were decreased dependent on treatment concentration.
Conclusion : This study showed that Millettia Reticulatas have the inhibitory effect on the proliferation of human uterine leiomyoma cell and the effect was related with apoptosis. The apoptotic mechanism was observed that the gene expression of p27, p53, p21, p16 related cell cycle was increased according to increasing treatment concentration, induced G1 phase arrest and finally cell death was occurred. The decreased expression of pro-caspase 3 and PARP were noted that apoptosis was related with caspase pathway.
