Abstract

The mechanisms of chronic hepatitis C virus (HCV)-induced liver fibrosis and hepatocarcinogenesis are still poorly recognized. Therefore, this study aimed to determine the effect of chronic HCV infection on the expression of the major regulators of epithelial-mesenchymal transition (EMT) including E-cadherin, Snail, Slug, and Twist2, in the Egyptian population. This will help to design more efficient strategies to treat HCV-associated cirrhosis and carcinoma. Fifty-nine liver biopsies from patients, that were serologically proven to be HCV positive, were included in the current study. Histopathological examination was done. Grading of hepatitis activity (A) and staging of fibrosis (F) were assessed using the METAVIR Scoring System. Additionally, an immunohistochemical examination of E-cadherin, Snail, Slug, and Twist2 expression was performed. E-cadherin showed a significant progressive decline of its expression with increased fibrosis staging and development of hepatocellular carcinoma (HCC). In contrast, Snail and Slug expression was positively associated with the stage of fibrosis and HCC. Meanwhile, Twist2 expression was not affected by the degree of hepatitis activity, the stage of fibrosis, or by the development of HCC. E...Continue Reading

Cadherins and Catenins

Cadherins (named for "calcium-dependent adhesion") are a type of cell adhesion molecule (CAM) that is important in the formation of adherens junctions to bind cells with each other. Catenins are a family of proteins found in complexes with cadherin cell adhesion molecules of animal cells: alpha-catenin can bind to β-catenin and can also bind actin. β-catenin binds the cytoplasmic domain of some cadherins.
