摘要 目的探讨肝细胞黏附分子(HEPACAM)基因转染肾癌细胞对其凋亡的影响。方法将携带HEPACAM基因的重组质粒转染786-0细胞,RT-PCR鉴定HEPACAM基因在786-0中的表达;Hoechst染色结合荧光显微镜观察细胞形态改变;FCM检测细胞周期及细胞凋亡情况;Western印迹法检测BAX、BCL-2、Cyclin D1蛋白表达变化。结果上调HEPACAM基因表达可诱导786-0细胞凋亡,阻止细胞周期于G0/G1期,并可上调BAX及下调BCL-2和Cyclin D1蛋白水平表达。结论外源导入HEPACAM基因可诱导肾癌细胞凋亡并阻止细胞周期于G0/G1期。 Objective To investigate the effect of transfection of hepatocyte cell adhesion molecule（HEPACAM） on apoptosis of renal cell carcinoma cells.Methods The vector containing HEPACAM gene was transfeceted into 786-0 cells,the expression of HEPACAM gene in 786-0 cells was confirmed by RT-PCR;The morphological change of nucleus was shown by Hoechst staining;The proliferation and apoptosis of 786-0 cells were analyzed by FCM;The expression of BAX,BCL-2,Cyclin D1 was measured by Western blot.Results Up-regulated expression of HEPACAM gene in 786-0 cells can arrest cell cycle at G0/G1 phase and induce cell apoptosis,the expression of BAX increased and the expression of BCL-2 and Cyclin D1 decreased.Conclusion Ectogenic transfected HEPACAM gene may induce cell apoptosis and arrest cell cycle at G0/G1 phase in renal cell carcinoma cells.
