Objective To construct HBVx-GFP eukaryotic expression plasmid and establish stable transfected HepG2 cell line expressing HBVx-GFP fusion protein for exploring the biological function of HBVx and its roles in carcinogenesis of hepatocellular carcinoma.

• 目的构建绿色荧光蛋白(GFP)与人乙型肝炎病毒(HBV)X基因的重组表达载体,建立稳定表达HBVX蛋白(HBx)与GFP融合蛋白的HepG2细胞系,以进一步研究HBx的生物学功能及其在肝癌发生中的作用。
