摘要 目的观察TGFβ1基因codon10(Leu>Pro)的单核苷酸多态性(SNP)对肝脏细胞功能的影响。方法构建含codon10(Leu>Pro)的TGFβ1(LAP+成熟态单体)真核表达重组体CMV-Leu、CMV-Pro。在HepG2、LX-2细胞中转染pcD-NA3.1空载体、CMV-Leu、CMV-Pro,培养24h后,ELISA检测细胞培养上清液中TGFβ1的分泌量。MTT实验观察HepG2细胞转染后的增殖情况,流式细胞术检测LX-2细胞转染后CD83的表达。结果转染CMV-Leu和CMV-Pro能增加HepG2、LX-2细胞的TGFβ1分泌量,且转染CMV-Pro的细胞TGFβ1分泌量比转染CMV-Leu的细胞高(P<0.05)。转染CMV-Pro能明显增高HepG2细胞的增殖活性(P<0.01),而转染CMV-Leu能明显增加LX-2细胞CD83的表达率(P<0.01)。结论TGFβ1基因codon10(Leu>Pro)的SNP对肝脏细胞TGFβ1的分泌、细胞增殖活性及CD83的表达具有明显影响。
