摘要 目的进一步探讨肾上腺髓质素(ADM)在肾癌新生血管生成及肿瘤进展中作用。方法将生长良好的人肾癌786-o细胞随机分为三组,其中空白对照组不行特殊处理;ADM组加入100 nM的ADM;ADM受体抑制剂组同时加入100 nM的ADM+1μM受体抑制剂。以上三组均加入RPMI1640培养基,置于含5%CO2、饱和湿度的37℃孵箱中,分别于培养24、48、72 h后收获细胞,分别采用Western blot和RT-PCR检测VEGF蛋白和VEGF mRNA表达。结果 ADM组VEGF蛋白及VEGF mRNA表达均显著高于ADM受体抑制剂组及空白对照组,尤以作用48、72 h为著(P<0.05、0.01);后两组比较无显著差异。结论 ADM可能通过调节VEGF表达参与肾癌新生血管生成、进而促进肿瘤发展。
