摘要: 目的: 探讨夏枯草总三萜(TTP)对乙醛刺激的大鼠肝星状细胞(HSC)-T6增殖、凋亡的影响及部分作用机制。方法: 用不同浓度的TTP(10、30、100、300、1000 μg/mL)对乙醛刺激的HSC-T6进行处理,四甲基偶氮唑蓝(MTT)法检测细胞增殖;流式细胞仪检测细胞凋亡;RT-PCR法检测HSC-T6中平滑肌肌动蛋白(α-SMA)、Ⅰ型前胶原(ProcollagenⅠ)、TGF-β信号转导通路下游中介分子Smad2、Smad3、Smad7 mRNA表达。结果: TTP可抑制乙醛刺激的大鼠HSC-T6增殖,诱导其凋亡,下调HSC-T6中α-SMA、ProcollagenⅠ、Smad2、Smad3的mRNA表达,上调Smad7的mRNA表达。结论: TTP对乙醛刺激的HSC-T6增殖具有抑制作用,并能够促进其凋亡,下调α-SMA、ProcollagenⅠ表达量,其机制可能与TTP能抑制Smad2、Smad3表达,升高Smad7的表达,从而对TGF-β/Smad信号通路发挥调控作用有关。

Abstract: AIM: To investigate the effects of total triterpenoids of prunella vulgaris L.(TTP) on proliferation and apoptosis in hepatic stellate cell-T6 (HSC-T6) stimulated by acetaldehyde and its partial mechanisms.METHODS: HSC-T6 cells were stimulated by acetaldehyde and treated with different doses of TTP (10, 30, 100, 300, 1000 μg/mL), the HSC-T6 proliferation were detected by MTT, the apoptosis rate were analyzed by flowcytometry, and the expression of mRNA levels of α-SMA, ProcollagenⅠ, smad2, smad3, smad7 were detected by RT-PCR.RESULTS: As compared with the model group, TTP could inhibit HSC-T6 stimulated by acetaldehyde and induce the apoptosis. Furthermore, TTP reduced the mRNA expression of α-SMA, ProcollagenⅠ, Smad2, Smad3 and increase Smad7.CONCLUSION: TTP can inhibit the proliferation of HSC-T6 stimulated by acetaldehyde and induce the apoptosis, down-regulate the expression of α-SMA, ProcollagenⅠ, which might be associated with the inhibition of the expression of Smad2、Smad3 and the increase of Smad7
