摘要 目的探讨重组人红细胞生成素(rhEPO)预处理对缺氧/复氧后SK-N-SH神经母细胞凋亡的影响及丝裂原活化蛋白激酶(P38MAPK)信号通路的作用。方法 SK-N-SH细胞随机分成对照组、Cocl2组、rhEPO组和SB203580组。MTT法测定细胞增殖,RT-PCR技术检测bcl-2、caspase-8、和P38MAPK mRNA的表达。结果 rhEPO预处理可以增加SK-N-SH细胞的增殖能力,上调bcl-2和P38MAPK基因的表达,下调caspase-8的表达,而这些调节作用可被SB203580抑制。结论 rhEPO预处理对缺氧/复氧后的SK-N-SH细胞有保护作用,P38MAPK通路起到重要的作用。
