Effect of TSLC1 gene on proliferation, invasion and apoptosis of human hepatocellular carcinoma cell line HepG2
The recombinant plasmid pCI-TSLC1 carrying TSLC1 gene was stably transfected into human hepatocellular carcinoma cell line HepG2. Cell proliferation was analyzed by MTT assay. The ability of migration was determined by transwell and FACSort flow cytometry was used to detect the cell cycle distribution and apoptosis. Western blotting revealed that H4 expressed higher amounts of TSLC1 protein than H15 and H0 did. The growth of TSLC1-transfected cells was significantly suppressed in vitro, and the ability of migration was reduced as well. The re-expression of TSLC1 could induce cell apoptosis. It was concluded that TSLC1 strongly inhibited the growth and ability of migration of HepG2 cell line in vitro and also induced apoptosis, suggesting that TSLC1 could reduce the tumorigenicity of human hepatocellular carcinoma cell line HepG2 in vitro, which provided a basis for further exploring the roles of TSLC1 in hepatocellular cellular carcinoma.
