Abstract:

OBJECTIVE: To explore the effects of cistanche phenylethanoid glycosides (CPhGs),acteoside and echinacoside on anti-proliferation and induction of apoptosis in hepatic stellate cells (HSC-T6) in vitro. METHODS: HSC-T6 cells were treated with different concentrations of CPhGs (25,50,100 μg/mL),acteoside (1.5,3,6.0 μg/mL) or echinacoside (125,250,500 μg/mL) for 48 h. The MTT methods was used to measure the anti-proliferation effect and half the inhibition rate (IC50) of HSC-T6. Proportions of apoptosis were assayed by flow cytometry. Western blot was used to detect the effects of the expression of Bcl-2 and Bax. RESULTS: With increasing concentrations of the three chemicals,the rate of inhibition of proliferation increased gradually. IC50 were 119.1,7.0 and 520.3 μg/mL for the three chemicals,respectively. The proportions of apoptosis for the three chemicals were significantly different from that of the untreated controls (P < 0.01). The highest apoptosis rates for CPhGs (at 100 μg/mL),acteoside (6.0 μg/mL) and echinacoside (500 μg/mL) were 24.40%±3.16%,34.73%±1.16% and 21.13%±0.98%,respectively. Except for the 1.5 μg/mL acteoside group,expression of Bcl-2/Bax was significantly decreased (P < 0.05) compared to the normal control group. CONCLUSION: CPhGs,echinacoside and acteoside caused proliferation inhibition and apoptosis. The sequence of the hepato-protective effects of the three chemicals was shown to be acteoside > CPhGs > echinacoside.
