摘要
目的 探究CYP2C9 是否参与肝细胞癌(hepatocellular carcinoma,HCC)的发生发展及其对肝癌细胞迁移、侵袭和增殖的影响.方法 从TCGA数据库中提取HCC的转录组数据,分析CYP2C9 在HCC中的表达和预后相关性;构建HepG2 和MHCC97H的CYP2C9 稳定过表达细胞系,通过Transwell迁移实验、Transwell 侵袭实验和Western Blot实验分别检测过表达CYP2C9 对肝癌细胞系迁移、侵袭能力以及上皮间质转化(epithelial-mesenchymal transition,EMT)过程的影响;通过CCK-8 实验、平板克隆形成实验和Western Blot实验检测过表达CYP2C9 对肝癌细胞系增殖能力的影响.结果 通过生信分析发现,CYP2C9 在HCC中的表达显著下调,且CYP2C9 的表达与HCC患者的临床预后呈正相关;细胞及分子实验结果显示,过表达CYP2C9 显著抑制HepG2 细胞和MHCC97H细胞的迁移、侵袭能力和EMT过程,而对细胞的增殖能力没有显著影响.结论 CYP2C9 可能通过抑制肝癌细胞的迁移、侵袭以及EMT过程,进而影响HCC的进展.
Abstract
Objective To explore whether CYP2C9 is involved in the occurrence and development of hepatocellular carcinoma(HCC)and its function in the migration,invasion and proliferation of HCC cells.Methods The transcriptome data of HCC were retrieved from the TCGA database to analyze the expression of CYP2C9 and role of CYP2C9 in the prognosis of HCC;Constructing stable CYP2C9 overexpression cell lines of HepG2 and MHCC97H,detecting the effects of CYP2C9 overexpression on the migration,invasion and epithelial mesenchymal transition(EMT)process of HCC cells through Transwell migration assay,Transwell invasion assay,and Western Blot assay,respectively;The effect of CYP2C9 overexpression on the proliferation ability of HCC cells was detected through CCK-8 assay,colony formation assay,and Western Blot assay.Results Bioinformatics analysis showed that the expression of CYP2C9 was significantly downregulated in HCC,and the expression of CYP2C9 was positively correlated with the clinical prognosis of HCC patients;The results of cellular and molecular experiments showed that CYP2C9 overexpression significantly inhibited the migration,invasion and EMT process of HepG2 and MHCC97H cells,whereas had no significant effect on cell proliferation.Conclusion CYP2C9 may affect the progression of HCC by inhibiting the migration,invasion,and EMT processes of HCC cells.
