摘要 目的探讨赖氨酸特异性组蛋白去甲基化酶1(LSD1)、E-钙黏蛋白、N-钙黏蛋白的表达与结肠癌细胞侵袭转移的相关性。方法利用Transwell体外细胞侵袭实验检测结肠癌细胞株Lovo、SW620、HT-29、HCT-8、HCT-116和对照细胞(HEK293)的侵袭性,再利用Real-time RT-PCR和Western blot实验方法检测LSD1、E-钙黏蛋白、N-钙黏蛋白在上述细胞中的表达,分析其与结肠癌细胞侵袭性的相关性。结果 SW620细胞中LSD1和N-钙黏蛋白的mRNA和蛋白水平明显高于其他4种结肠癌细胞和正常对照细胞(F=149.594,P<0.05;F=367.29,P<0.05),而E-钙黏蛋白mRNA和蛋白水平明显低于其他4种结肠癌细胞和正常对照细胞(F=51.23,P<0.05)。Transwell细胞侵袭实验显示SW620细胞的侵袭性明显高于其他4种结肠癌细胞和正常对照细胞(F=300.15,P<0.05)。相关性分析显示LSD1、N-钙黏蛋白的表达与结肠癌的侵袭性呈正相关,E-钙黏蛋白的表达与结肠癌的侵袭性呈负相关。结论 LSD1、N钙黏蛋白的表达与结肠癌细胞的侵袭性呈正相关,E钙黏蛋白的表达与结肠癌细胞的侵袭性呈负相关,三者可能在结肠癌的侵袭转移过程中发挥了重要作用。
