摘要 目的观察体外高糖环境对H9C2心肌细胞增殖的影响,并探讨其作用机制。方法将体外培养鼠胚心肌细胞H9C2随机分为四组,1组培养液中加入终浓度为5.5 mmol/L的D-葡萄糖,2组加入终浓度为27.5 mmol/L的甘露醇和5.5 mmol/L的D-葡萄糖,3组加入终浓度为33 mmol/L的D-葡萄糖,4组加入终浓度为2μmol/L的经典瞬时受体蛋白(TRPC)阻滞剂SKF96365和终浓度为33 mmol/L的D-葡萄糖。分别在培养24、48、72 h时,采用CCK8法测定细胞增殖率,实时定量PCR法测定经典瞬时受体蛋白6(TRPC6)、活化T细胞核因子3(NFAT3)mRNA;72 h时采用Western blotting法检测TRPC6及NFAT3蛋白。结果培养72 h时1、2、3、4组细胞增殖率分别为105.88%±10.01%、98.67%±8.97%、28.55%±6.32%、49.18%±7.14%,3组较1、2组降低(P均<0.05),4组较3组增高(P<0.05);3组TRPC6、NFAT3 mRNA及蛋白相对表达量较1、2组增加(P均<0.05),4组较3组下降(P均<0.05)。结论高糖抑制心肌细胞增殖;促进心肌细胞TRPC6表达,导致TRPC通道开放,启动钙调神经素(Ca N)/活化T细胞核因子(NFAT)通路,可能是其作用机制。
