摘要:
为探讨缝隙连接是否参与抑制大鼠血管平滑肌细胞的增殖及可能的分子机制,本研究以原代及传代培养大鼠胸主动脉平滑肌细胞为模型,实验分2组:对照组,缝隙连接阻断剂18α-甘草次酸(18α-Glycyrrhetinic acid,18α-GA)组.MTT法及流式细胞术检测细胞的增殖活性,染料示踪分子传递法(划痕标记染料传输法)检测细胞的缝隙连接功能,Western blotting法检测细胞中缝隙连接蛋白40(Cx40)和43(Cx43)表达.结果显示:(1)与对照组相比,18α-GA组MTT法测得的A570值及细胞周期S期比例均降低(P0.01),细胞增殖活性减弱;(2)与对照组相比,18α-GA组罗氏黄荧光染料传递百分数显著降低,缝隙连接功能明显减弱(P0.01);(3)与对照组相比,18α-GA组Cx40和总Cx43蛋白表达无显著差异(P0.05),磷酸化Cx43与非磷酸化Cx43的比值显著降低(P0.01).由此可知,18α-GA可能主要通过下调血管平滑肌细胞磷酸化Cx43蛋白表达,引起缝隙连接通讯功能减弱,从而抑制了血管平滑肌细胞的增殖.

摘要:
目的探讨18α-甘草次酸对游离脂肪酸(FFAs)致HepG2细胞脂毒性的保护作用及经线粒体途径调节的分子机制.方法给予1 mmol/L FFAs,油酸(OA)–棕榈酸(PA)(2:1)建立体外HepG2细胞脂肪变性模型,细胞分为对照组,模型组和18α-甘草次酸低,中,高剂量(10,20,40μmol/L)组,阳性药(凋亡抑制剂Z-VAD-FMK,10μmol/L)组,采用MTT法检测细胞活力,用Hoechst33258染色法观察细胞凋亡;免疫荧光染色法观察Bax蛋白激活情况;Western blotting检测细胞色素C在线粒体和胞浆的分布情况;Caspase-3酶活检测试剂盒测定细胞内Caspase-3活性.结果18α-甘草次酸能保护FFAs致HepG2细胞活力下降,减少HepG2细胞脂性凋亡数量;18α-甘草次酸能下调Bax蛋白激活,减少细胞色素C的释放,从而阻止Caspase-3活性的增高,且呈剂量相关性.结论18α-甘草次酸对FFAs致HepG2细胞的脂毒性中存在保护作用,其作用机制与抑制线粒体凋亡通路有关.
