| Abstract: | Objective To investigate the effect of Baicalin on hepatic stellate cells through iNOS/PUMA signaling pathway.Methods The inhibition rate of cell proliferation is detected by MTT,the expression of iNOS and PUMA proteins are detected by Western Blot,the expression of PUMA mRNA is detected by real-time PCR,the level of NO is detected by NO assay kit,the inhibition rate of cell proliferation and PUMA expression are detected after pretreatment with iNOS inhibitor L-NAME,and apoptosis is detected by Hoechst 33342 nuclear staining.Results 50 mM Baicalin induced activation-induce death of HSCs;Baicalin promot the expression of PUMA mRNA and protein in HSCs;PUMA expression and apoptosis are decreased after pretreatment with iNOS inhibitor L-NAME.Conclusion Baicalin promote HSCs apoptosis through iNOS/PUMA signaling pathway. |
