摘要 目的探讨SK-7041在血管紧张素Ⅱ(AngⅡ)致心肌细胞肥大过程中的抑制作用。方法常规方法培养大鼠原代心肌细胞,分为3组:对照组、肥大组、SK-7041组。利用AngⅡ刺激心肌细胞造成肥大模型,并给予SK-7041进行干预。反转录聚合酶链反应观察β-肌球蛋白重链(β-MHC)mRNA表达;相差显微镜和电镜观察心肌细胞的表面积和超微结构变化;免疫组织化学法检测c-fos蛋白的表达。结果大鼠原代心肌细胞在AngⅡ作用下表面积增加,超微结构发生改变;β-MHC mRNA和c-fos蛋白表达增加(P<0.05)。给予SK-7041干预后,上述变化显著缓解(P<0.05)。结论 SK-7041可抑制AngⅡ刺激引起的心肌细胞肥大,为临床上治疗心肌肥厚提供一条新的思路。
