Objective To investigate the effect of MG 132 on apoptosis of the activated rat hepatic stellate cells(HSC).Methods HSC were isolated from rats with collagenase in situ liver recirculating perfusion.Apoptosis was analyzed by flow cytometry(FCM) and agarose gel electroporesis.Results Admilistrition of 1~3 μmol/L MG 132 could significantly inhibit HSC proliferation in dose dependent manner(P<0.01).After treated with MG 132 in at different concentration of 1~3 μmol/L for 24 h,the number of in G2/M phase increa...
