摘要:
目的 探讨在结直肠癌细胞中沉默KIF4A基因后,对细胞增殖及周期的影响以及相关机制.方法 分别使用KIF4A-CtrlRNA(si-Ctrl)及KIF4A-siRNA(si-KIF4A)瞬时转染结直肠癌细胞株SW480和DLD1,通过Western blot验证干扰效果;CCK8实验检测干扰KIF4A后SW480和DLD1细胞的增殖能力;流式细胞术检测干扰KIF4A后对细胞周期的影响;Western blot检测周期相关蛋白Cyclin D1、Cyclin E2和CDK2表达水平的变化.结果 si-KIF4A组较si-Ctrl组细胞增殖能力显著下降;细胞周期出现G0/G1周期阻滞;周期相关蛋白Cyclin D1、Cyclin E2和CDK2的蛋白表达水平下降.结论 KIF4A通过上调周期蛋白Cyclin D1、Cyclin E2和CDK2的表达促进结直肠癌细胞的增殖.
Abstract:
ob＜x＞jective To investigate the effect and relate d mechanism of KIF4A on cell proliferation and cell cycle of colorectal cancer cells. Methods The KIF4A-CtrlRNA ( si-Ctrl) and KIF4A-siRNA ( si-KIF4A) were transiently transfect ed into colorectal cancer cell lines SW480 and DLD1, Western b lot was used to verified the effect of knocking down; the changes of cell p roliferation of SW480 and DLD1 colorectal cells were confirmed by CCK8 assay; flow cytometry was performed to analyze the effect of KIF4A on cell cycle; the changes of cell cycle-related proteins Cyclin D1, Cyclin E2 and CDK2 were performed by Western blot. Results Comparing the si-KIF4A group with si-Ctrl group, the ex＜x＞pression of KIF4A was significantly reduced; the cell proliferation was dramatically decreased; the cell cycle was arrested at G0/G1 phase and the cell cycle-related proteins Cyclin D1, Cyclin E2 and CDK2 were downregulated. Conclusion KIF4A promotes the cell proliferation via upregulating the ex＜x＞pression of Cyclin D1, Cyclin E2 and CDK2
