摘要 目的探讨Beclin1、Livin在人的结肠癌组织、不同类型结肠腺瘤组织及结肠正常黏膜中的表达水平的变化规律及临床意义。方法采用免疫组化染色方法及逆转录-聚合酶链反应(reverse transcription-poly-merase chain reaction,RT-PCR)方法检测结肠癌组织(A组)、结肠绒毛状腺瘤(B组)、结肠管状腺瘤(C组)及结肠正常黏膜(D组)中Beclin1、Livin蛋白和mRNA的水平。结果 A、B、C、D 4组中Beclin1蛋白的相对积分光密度值分别为156.02±3.58,129.82±4.93,125.01±4.58,104.60±2.81,差异有统计学意义(F=270.85,P=0.000);A、B、C、D 4组中Livin蛋白的相对积分光密度值分别为157.75±2.93,137.54±3.93,126.58±3.68,99.41±2.15,差异有统计学意义(F=560.25,P=0.000);Beclin1 mRNA在A、B、C、D 4组中的相对表达量分别为0.93±0.11,0.22±0.02,0.13±0.01,0.06±0.02,差异有统计学意义(2=36.63,P=0.000);Livin mRNA在A、B、C、D 4组中的相对表达量分别为0.94±0.44,0.44±0.04,0.14±0.05,0.02±0.01,差异有统计学意义(2=36.62,P=0.000)。结论 Beclin1和Livin的表达水平在结肠正常黏膜、结肠管状腺瘤、结肠绒毛状腺瘤、结肠癌组织呈逐渐增高趋势,提示Beclin1和Livin在结肠黏膜癌变过程中起着一定作用。
