摘要 目的探究人类白细胞抗原复合体(HCG)11对肺癌细胞增殖、迁移、侵袭的影响和机制。方法实时荧光定量-聚合酶链反应(qRT-PCR)检测46例肺癌组织样本和与其配对的癌旁组织样本中HCG11和miR-1297的表达。以肺癌细胞A549为研究对象,建立过表达HCG11的细胞株,四甲基偶氮唑蓝(MTT)比色法检测细胞活力,Transwell法检测细胞迁移和侵袭能力,Western印迹检测细胞周期蛋白(Cyclin)D1、P21、E-钙黏附蛋白(E-cadherin)和基质金属蛋白酶(MMP)-2蛋白表达情况。双荧光素酶报告实验和Western印迹验证HCG11和miR-1297的靶向关系。结果与癌旁组织比较,肺癌组织中HCG11的表达显著下调,miR-1297的表达显著上调(均P<0.05)。过表达HCG11可显著抑制CyclinD1和MMP-2蛋白表达,促进P21和E-cadherin表达,抑制A549细胞增殖、迁移和侵袭(均P<0.05)。miR-1297是HCG11的靶基因,HCG11可负性调控miR-1297的表达。过表达miR-1297可逆转HCG11对A549细胞增殖、迁移和侵袭的抑制作用。结论HCG11通过靶向下调miR-1297表达可抑制肺癌细胞增殖、迁移和侵袭。
