  Data on the onset and progression of fibrosis related to c-MYC protein expression in chronic hepatitis by C virus are scarce. In this work we evaluated by immunohistochemical method the expression of c-MYC protein in the liver parenchyma without fibrosis, and during its progression. Seventy-eight liver samples from Hepatitis C virus infected patients with different degrees of fibrosis (F0 to F4) were studied. Eleven healthy liver samples were included. All samples from chronic hepatitis were stained by hematoxylin-eosin method, and classified by METAVIR scoring system. The expression of c-MYC protein was evaluated in 1000 hepatocytes from each parenchyma area by immunohistochemistry. Results showed that c-MYC expression in hepatocytes from fibrosis samples (F1-F4) was higher, and statistically significant (P<0.05) when compared with the control group. The same results were obtained.. View More»
