Objective:To investigate the effects of ursolic acid on proliferation and apoptosis of hepatic carcinoma cell line HepG2 and its partial mechanism.Methods:The human HepG2 cells were cultured by different concentrations of ursolic acid.The inhibitions of ursolic acid on cell proliferation were determined by using MTT.The effects of ursolic acid on on cell apoptosis and cell cycle were detected by using flow cytometry.The expressions of pERK1/2 and Cyclin D1 proteins after culturing by different concentrations of ursolic acid were tested by using Western blotting.Results:The human hepatoma HepG2 cell proliferations were inhibited by different concentrations of ursolic acid,and the effects showed dose and time-dependent manner(P＜0.05).The cell apoptosis rate for human hepatoma cell line HepG2 was achieved to the maximum under 60 μ mol/L ursolic acid for 72 h,which was (78.723 ± 3.623)％.Ursolic acid could significantly increase the Go/G1 phase cells proportion,and induce HepG2 apoptosis.Ursolic acid could inhibit the expressions of pERK1/2 and Cyclin D1 proteins,and inhibitory effects showed more apparent along with the concentration and time gradually increasing.Conclusion:Ursolic acid could inhibit the proliferation of human hepatic carcinoma HepG2 cell line,block of cells in G0/G1 phase,and promote the cell apoptosis.This might be related with down-regulation of the expressions of pERK1/2 and Cyclin D1 proteins.

Objective To explore whether physiological doses of testosterone therapy can modulate cardiomyocyte aging via classical androgen receptor (AR) dependent pathways.Methods Male C57BL/6J mice and testicular feminized (Tfm) mice were divided into five experimental groups:the control group (n=8),the castrated group (n=8),the Tfm group (n=7),the testosterone treated castrated group (n=8),and the testosterone-treated Tfm group (n =8).After isolation of cardiomyocytes from the left ventricle,the activity of superoxide dismutase (SOD) and the amount of malondialdehyde (MDA) were measured using colorimetry,and the expression of the p16INK4a and retinoblastoma (Rb) proteins was detected by Western blotting.Results Compared with the control group,the activity of SOD in the castrated group and the Tfm group declined [(16.55±1.18) U/ml,(17.30±1.32) U/ml vs.(21.57±2.21)U/ml,P＜0.05)],the amount of MDA increased [(7.78±1.27)μmol/L,(6.52±0.82)μmol/L vs.(3.48±0.70)μmol/L],P＜0.01,and the expression of both the p16INK4aand Rb proteins increased [(0.37±0.08),(0.45±0.06) vs.(0.14±0.02),forp16INK4a,P＜0.05; (0.74±0.05),(0.79±0.08) vs.(0.40±0.05),for Rb,P＜0.05].Compared with the castrated group,the activity of SOD in the testosterone treated castrated group increased [(23.00±0.58)U/ml vs.(16.55±1.18) U/ml,P＜0.01],the amount of MDA decreased [(2.63±0.90) μmol/L vs.(7.78±1.27) μmol/L,P＜0.01],and the p16INK4a and Rb proteins were both downregulated (0.13 ± 0.03 vs.0.37± 0.08),for p16INK4a,P＜0.05; (0.45 ±0.05) vs.(0.79±0.08),for Rb P＜0.05.Compared with the Tfm group,the activity of SOD in testosterone-treated Tfm group increased,the amount of MDA decreased,and the p16IN4a and Rb proteins were both downregulated (P＜ 0.05).No significant differences in these markers were detected between the testosterone-treated castrated group and the testosterone-treated Tfm group.Conclusions Physiological doses of testosterone can retard cardiomyocyte aging via androgen receptor independent pathways.
