The mechanisms of hepatitis C virus (HCV)-associated hepatocarcinogenesis and disease progression are unclear. We previously observed that the expression level of carboxypeptidase B2 (CPB2) gene was remarkably suppressed by persistent HCV RNA replication in human hepatoma cell line Li23- derived cells. The results of the present study demonstrated that the CPB2 expression in patients with chron...

Mutational activation of beta-catenin and cyclin D1 over-expression are a frequent change in mouse hepatic tumors. Although activated beta-catenin may bind to T cell factor (TCF) family members and transcriptionally activate the cyclin D1 gene, either beta-catenin or cyclin D1 may be activated by various pathways independently of beta-catenin mutations. In this study, we investigated beta-caten...

Mutations affecting phosphorylation sites in the beta-catenin gene have been implicated in the development of human and rodent hepatocellular carcinomas (HCCs). To further investigate the involvement of this gene in hepatocarcinogenesis, we used several transgenic mouse models of hepatic tumors induced by overexpression of c-myc in the liver either alone or in combination with transforming grow...

The differentiation status of tumor cells, defined by histomorphological criteria, is a prognostic factor for survival of patients affected with intrahepatic cholangiocarcinoma (ICC). To strengthen the value of morphological differentiation criteria, we wished to correlate histopathological differentiation grade with expression of molecular biliary differentiation markers and of microRNAs previ...

Objective(s): Hepatic ischemia/reperfusion injury (IRI) is one of the major causes of hepatic failure during liver transplantation, trauma, and infections. The present study investigated the protective effect of intra-portal administration of 2-methoxycinnamaldehyde (2-MCA) on hepatic IRI in rats. Materials and Methods: Twenty-four rats ...

Inborn errors of mitochondrial beta-oxidation cause ectopic fat accumulation, particularly in the liver. Fatty liver is associated with insulin resistance and predisposes to hepatic fibrosis. The factors underlying the pathophysiological consequences of hepatic fat accumulation have remained poorly defined. Gene expression profiling in a model of acute fatty liver disease induced by blocking lo...

This study designed the normal diet (Con), high-lipid (HL), and 50 mg/kg berberine supplemented Con HL diets (named as ConB HLB, respectively). Fingerling black sea bream (Acanthopagrus schlegelii) (initial weight 1.47 ± 0.03 g) were fed these four for 8 weeks, liver immune response intestinal health ev...

BACKGROUND Under compromised biliary regeneration, transdifferentiation of hepatocytes into biliary epithelial cells (BEC) has been previously observed in rats, upon exposure to BEC-specific toxicant methylene dianiline (DAPM) followed by bile duct ligation (BDL), and in patients with chronic biliary liver disease. However, mechanisms promoting such transdifferentiation are not fully understood...
