Background: Hepatitis B virus (HBV) X (HBx) protein is associated with hepatocellular carcinogenesis via the induction of malignant transformation and mitochondrial dysfunction. However, the association between HBx and histone methyltransferase in carcinogenesis has not been fully clarified. In the current study, we analyzed the association between HBx and the histone methyltransferase suppressor of variegation 3-9 homolog 1 (SUV39h1) using HBV replication models.

We report a 46-year-old male patient with functional liver damage due to hepatitis B virus infection. A 12 cm hepatocellular carcinoma (HCC) in the left lobe and portal venous tumor thrombosis (PVTT) with vp4 (portal vein tumor thrombosis in the main trunk) were detected by computed tomography (CT). He underwent hepatic arterial infusion chemotherapy (HAIC) with cisplatin 100 mg for HCC and received radiation therapy (39 Gy/13 Fr) for PVTT with vp4.

Aim: Treatment with all-oral direct-acting antiviral agents (DAAs) elbasvir/grazoprevir (EBR/GZR) is associated with high sustained virologic response (SVR). The aim of this study was to evaluate the safety and treatment efficacy of EBR/GZR in hepatitis C virus (HCV)-infected patients.

Methods: This retrospective cohort study included 147 consecutive patients with chronic HCV genotype 1b infection who were treated with EBR (50 mg) plus GZR (100 mg) once daily for 12 weeks.
