Hepatitis B virus (HBV) X protein (HBx) serves an important role in HBV infection and the development of HBV‑related liver cancer. Interferon‑α (IFN‑α) is used to treat patients with HBV; however, the role of IFN‑α in the development of HBV‑related liver cancer remains unclear. The present study established a new HBV‑related liver cancer model (Huh‑7‑HBx) by transfecting the hepatoma cell line Huh‑7, with HBx‑expressing lentivirus. Following IFN‑α treatment, cell viability, migration and invasion, as well as the expression of antiviral proteins in Huh‑7‑HBx, were subsequently determined. The results demonstrated that HBx‑expressing lentivirus had no significant effect on cell viability but promoted the migration and invasion of Huh‑7 cells. The expression of the antiviral genes IFN α and β receptor subunit 1 (IFNAR1), IFNAR2, IFN‑stimulated gene factor 3, double‑stranded RNA‑activated protein kinase and ribonuclease L, was also increased. Following treatment of Huh‑7‑HBx cells with IFN‑α, the expression of antiviral genes was increased at the level of transcription and translation, whereas cell migration and invasion was decreased. The present study suggests that IFN‑α may attenuate the development of HBV‑related liver cancer by reducing cell migration and invasion and promoting the expression of antiviral proteins.
