摘要 目的探讨PHLPP1在结直肠癌中的表达规律及临床意义。方法采用免疫组织化学实验检测10例结直肠癌组织石蜡标本中PHLPP1蛋白水平的表达情况;同时运用western blot实验和实时荧光定量PCR实验检测10对新鲜结直肠癌组织及配对的癌旁组织中PHLPP1蛋白和mRNA的表达情况;另外运用实时荧光定量PCR实验检测52例新鲜结直肠癌组织中PHLPP1 mRNA的表达水平,并分析PHLPP1的表达水平与临床病理参数之间的关系。结果 western blot实验、免疫组织化学实验及实时荧光定量PCR实验的结果显示PHLPP1在结直肠癌组织中的表达水平均明显低于配对的癌旁组织,并且PHLPP1在结直肠癌组织中mRNA的表达水平与结直肠癌的分化程度、Ducks分期、淋巴结转移和远处转移相关等临床病理参数之间呈负相关(P<0.05)。结论结直肠癌组织中PHLPP1的表达水平显著下调,并且其表达水平与分化程度、Dukes分期、淋巴结转移和远处转移等临床病理参数之间呈负相关,PHLPP1在结直肠癌的发生、发展和转移的过程中可能发挥类似抑癌基因的作用。
