内皮素-1对培养新生大鼠心肌细胞原癌基因c-fos表达的诱导 总被引:9,自引:1,他引:8
本实验用无血清的培养新生大鼠心肌细胞,探讨内皮素1(ET1)对原癌基因cfos表达的作用。结果显示:ET1可显著诱导cfos的表达,其表达的高峰在30min,2h恢复到正常水平,并呈剂量依赖性反应和被ETA的特异性受体拮抗剂BQ123所阻断;蛋白激酶C(PKC)激动剂PMA可诱导cfos表达,而PKC抑制剂Staurosporine则可阻断ET1诱导的cfos表达;钙通道阻断剂硝苯吡啶预处理心肌细胞对ET1诱导的心肌细胞的cfos表达无明显的作用。这些结果提示,ET1诱导cfos表达是通过ETA受体介导的,PKC在此过程中起重要作用。 相似文献
