Abstract
AIM: To explore the influence of overexpression of hepatitis B virus X (HBX) on the proliferation and migration of hepatoma cells.
METHODS: Human hepatic carcinoma cell line Huh7 was cultured and infected with a recombinant adenovirus vector expressing HBX to establish an Huh7-HBX cell line. Colony forming assay, MTS assay and crystal violet staining were performed to assess cell proliferation. Cell migration assay was also performed.
RESULTS: The Huh7-HBX cell line was established successfully. HBX overexpression could promote cell proliferation. The number of cell colonies formed for Huh7-HBX cells was significantly higher than that for Huh7 cells (P < 0.05). Restoration of secreted frizzled-related protein 1 (SFRP1) and SFRP5 expression or knockdown of DNA methyltransferase 1 (Dnmt1) could significantly inhibit liver cancer cell proliferation and migration (P < 0.05).
CONCLUSION: Overexpression of HBX significantly inhibits the proliferation and migration of hepatoma cells.
