摘要 目的研究P38 MAPK通路在老年卵巢癌化疗药物耐药性产生中的作用,对可能的机制进行探讨。方法采用免疫组化法测定P38 MAPK、凋亡抑制蛋白Survivin、耐药相关蛋白切除修复交叉互补基因1(ERCC1),肺耐药相关蛋白(LRP),谷胱甘肽转移酶(GST-π)在25例老年原发性卵巢上皮癌和32例老年复发性卵巢上皮癌治疗前后标本中的表达情况。结果 P38 MAPK在原发性卵巢癌中的表达显著高于复发性卵巢上皮癌(P<0.01),而Survivin、ERCC1、GST-π的表达则明显低于复发性卵巢癌组(P<0.01),P38 MAPK与Survivin、ERCC1、LRP之间存在负相关性(P<0.01),但与GST-π之间无相关性(P>0.05)。结论化疗抑制了P38 MAPK信号通路,增加了Survivin、ERCC1、GST-π的表达,进一步导致了耐药性的发生,P38 MAPK信号通路开通可能是改善卵巢癌化疗效果的理论途径。
