摘要/Abstract

摘要： 目的探索G蛋白通路抑制因子2(G protein pathway suppressor 2,GPS2)对肝癌细胞增殖、迁移与侵袭的调控作用及分子机制。方法在肝细胞癌(HCC)细胞系MHCC-97H中,使用定量PCR或Western blot检测HCC细胞中GPS2等的表达水平;在HCC细胞中进行转染,分别使用GPS2的表达载体、GPS2基因的shRNA慢病毒载体在HCC细胞中对GPS2进行过表达或者敲低;同时采用克隆形成实验、划痕实验以及Transwell实验等检测GPS2对HCC细胞增殖、迁移与侵袭的影响。结果在HCC细胞中,过表达GPS2能够抑制HCC细胞系MHCC-97H的增殖、迁移与侵袭,而敲低GPS2能够上调其增殖、迁移与侵袭(P＜0.05)。进一步,在MHCC-97H细胞中过表达GPS2能够抑制EGFR、MMP1、MMP3以及MMP9等细胞增殖、迁移与侵袭相关因子的表达水平,而敲低GPS2的表达则能够上调这些因子的表达水平(P＜0.05)。结论 GPS2是新型HCC调控因子,能够抑制HCC细胞系的增殖、迁移与侵袭。

Abstract: Objective To explore the role of G protein pathway suppressor 2(GPS2)in regulating proliferation, migration and invasion in hepatocellular carcinoma cell line MHCC-97H.Methods The expression of GPS2 in hepatocellular carcinoma (HCC) cells were detected using quantitative PCR or Western blot; GPS2 was either over-expressed or knocked down in HCC cells using over-expression vectors or short hairpin RNAs (shRNAs) for GPS2, respectively. Clone formation assay, scratch assay and Transwell assay were used to detect the effects of GPS2 on proliferation, migration and invasion of HCC cells. Results In HCC cells, over-expression of GPS2 was found to inhibit the proliferation, migration and invasion of HCC cells MHCC-97H, while knockdown of GPS2 up-regulated proliferation, migration and invasion of MHCC-97H(P＜0.05). The over-expression of GPS2 in MHCC-97H cells was found to inhibit the expression of cell proliferation, migration and invasion-related factors such as EGFR, MMP1, MMP3 and MMP9, while knockdown of GPS2 upregulated the expression of these factors(P＜0.05). Conclusions GPS2 is a novel HCC regulatory factor that inhibits proliferation, migration and invasion of HCC cells.
