目的: phosphatas据报道,E和Tensin同源物(PTEN)充当肝星状细胞(HSC)激活的负调节剂。但是,迄今为止,尚未确定PTEN在LQ对肝纤维化的影响中的作用。 方法: LQ对碳纤维化(CCL)小鼠肝纤维化对肝纤维化的影响。 Moreover, the roles of PTEN and microRNA-181b (miR-181b) in the effects of LQ on liver fibrosis were examined. RESULTS: LQ markedly ameliorated CCl-induced liver fibrosis, with a reduction in collagen deposition as well asα-SMA level.此外,LQ诱导了PTEN的增加,并有效抑制了HSC激活,包括细胞增殖,α-SMA和胶原蛋白表达,这与姜黄素相似(阳性对照)。值得注意的是,PTEN的丢失阻止了LQ对HSC激活的影响。 PTEN被确认为mir-1的靶标81b和miR-181b介导的PTEN参与LQ对肝纤维化的影响。 LQ导致miR-181b表达显着降低。 LQ抑制的HSC激活可以通过miR-181b的过表达来恢复。进一步的研究表明,LQ通过SP1下调miR-181b水平。 Collectively, we demonstrate that LQ inhibits liver fibrosis, at least in part, via regulation of miR-181b and PTEN. CONCLUSION: LQ down-regulates miR-181b level, leading to the restoration of PTEN expression, which contributes to the suppression of HSC activation. LQ可能是针对肝纤维化的潜在候选药物。
