ABSTRACT
OBJECTIVE@#To determine the effect of tanshinone IIA on the growth and apoptosis in human hepatoma cell line HepG2.@*METHODS@#The human hepatoma cell line HepG2 was treated with tanshinone IIA at various concentrations for 72 h. The inhibition of proliferation was measured by MTT assay and apoptosis-related alterations in morphology measured by cytochemical staining (HT33258). DNA fragmentation was evaluated by agarose gel electrophoresis. Apoptotic rate and cell arrest were quantified by flow cytometry (FCM).@*RESULTS@#Tanshinone IIA inhibited the growth of HepG2 in a time- and dose- dependent manner. The semi-inhibitory concentration (IC50) value after the treatment with tanshinone IIA on HepG2 for 24, 48 and 72 h were 14.7, 7.4, and 3.9 microg/ mL, respectively. After the treatment with 0.5 - 10 microg/mL tanshinone IIA for 72 h, the formation of apoptotic bodies was observed. DNA ladder was shown in agarose gel electrophoresis, in addition to the cells treated by 1.0 microg/mL tanshinone IIA . The apoptotic rates at 0.5, 1.0, 2.0, 5.0, and 10.0 microg/mL for 72 h were 20.32%+/-2.16%, 28.0%+/-2.35%, 33.87%+/-3.43%, 46.73%+/-4.08% and 57.85%+/-3.74%, respectively, which were all significantly higher than those of the control group (P<0.05).@*CONCLUSION@#Tanshinone IIA can inhibit the proliferation of human hepatoma cell line HepG2 in a time- and dose- dependent manner, and the mechanism of growth inhibition of human hepatoma cells may be related to the induction of apoptosis.
