腺病毒介导的Hes1基因抑制肝细胞癌细胞的增殖与迁移CSCD

目的探讨Hes1基因对肝细胞癌细胞系Hep1-6细胞增殖、迁移与侵袭的影响。方法通过重组腺病毒载体介导Hes1基因在Hep1-6细胞系中过表达,随后测定细胞克隆形成率、增殖速率及体外迁移与侵袭能力的改变。结果Hep1-6细胞分别感染Ad-Hes1和阴性对照Ad-GFP后,感染Ad-Hes1的细胞系克隆形成数显著少于对照组(P<0.001);感染病毒6天后,CCK-8检测感染Ad-Hes1的细胞系在OD450 nm的吸光度值显著低于对照组(P<0.01);感染Ad-Hes1的细胞系24 h和48 h的划痕愈合率显著低于对照组(P<0.001);感染Ad-Hes1的细胞系在Transwell小室培养48 h后迁移进入Transwell下室的细胞数量显著低于对照组(P<0.001);感染Ad-Hes1的细胞系在铺有Matrigel基质胶的Transwell小室培养48 h后侵袭进入Transwell下室的细胞数量显著低于对照组(P<0.01)。结论Hes1有抑制Hep1-6细胞增殖、迁移与侵袭的作用。

Adenovirus-mediated Hes1 Expression Inhibits Proliferation and Migration of Hepatocellular Carcinoma Cells

Objective To investigate the effects of Hes1 gene on the proliferation, migration and invasionof hepatocellular carcinoma cell line Hep1-6. Methods Cell proliferation, cell colony formation, migration and invasion were measured after Hes1 gene were overexpressed in Hep1-6 cells mediated by recombinant adenovirus. Results The clone numbers of Hep1-6 cells infected with Ad-Hes1 were significantly less than the control group infected with Ad-GFP (P<0.001). Six days after Ad-Hes1 infection, OD450nm of Hep1-6 cells were significantly lower than that of control group (P<0.01). The wound healing rates of Hep1-6 cells infected with Ad-Hes1 at 24h and 48h were significantly lower than those of the control group (P<0.001). The number of Hep1-6 cells infected with Ad-Hes1 migrating into the lower chamber of Transwell after 48 h of culture was significantly lower than that of the control group (P<0.001). The number of Hep1-6 cells infected with Ad-Hes1 invading into the lower chamber of Transwell after 48h of culture was significantly lower than that in the control group (P<0.01). Conclusion Hes1 could suppress the proliferation, migration and invasion of Hep1-6 cells.
