The interaction between microRNA-152 and DNA methyltransferase-1 as an epigenetic prognostic biomarker in HCV-induced liver cirrhosis and HCC patients.

The necessity for early detection and hence improving the outcome of treatment of hepatocellular carcinoma (HCC) is critical especially in Hepatitis C virus (HCV)-Genotype 4 induced cases. In our current work, we examined the miRNA-152 and DNMT-1 expression in chronic liver disease (CLD) due to HCV genotype 4 infection with/without cirrhosis and HCC patients as an attempt to evaluate the potential benefits of these new circulating, noninvasive, prognostic, epigenetic markers for liver cirrhosis and carcinogenesis of Egyptian patients. Eighty subjects were included in this study, divided into two groups; group I (40 patients) were classified into subgroup Ia (CLD without cirrhosis, n = 18) and subgroup Ib (CLD with cirrhosis, n = 22), group II (CLD patients with HCC, n = 20), and control (Healthy volunteer, n = 20).

Monocyte adhesion molecules expression in patients with chronic hepatitis C liver disease.

Background: Chronic viral hepatitis is histologically characterized by predominantly periportal infiltration of mononuclear cells, including lymphocytes and monocytes/macrophages. Intralobular infiltration of these inflammatory cells is an ominous sign of deterioration and a criterion for disease activity.

Objective: To assess the monocyte inflammatory milieu, monocytes adhesion molecules, their endothelial receptors, cytokines and chemokines in patients with HCV induced chronic liver disease, in an attempt to clarify the role of blood monocytes in induction of inflammation and fibrogenesis in chronic hepatitis C liver disease.

Circulating and hepatic Fas expression in HCV-induced chronic liver disease and hepatocellular carcinoma.

Apoptosis is central for control and elimination of viral infections. In chronic hepatitis C virus (HCV) infection, enhanced hepatocyte apoptosis and upregulation of the death-inducing ligands CD95/Fas occur. This study aimed to study the role of serum soluble Fas and hepatic Fas expression as early predictors of advancement of chronic hepatitis C disease.

Expression of cyclooxygenase-2 and transforming growth factor-beta1 in HCV-induced chronic liver disease and hepatocellular carcinoma.

Unlabelled: Cyclooxygenase-2 (COX-2) and transforming growth factor-beta1 (TGF-beta1) were modulated in a variety of viral infections, but there is a paucity of data about their role in the pathologic process of cirrhosis and/or hepatocellular carcinoma (HCC) following chronic hepatitis C virus (HCV) infection. The material of the current study included 50 cases of chronic hepatitis C (CHC) without cirrhosis, 30 cases of CHC with cirrhosis, and 30 cases of HCC with HCV admitted to the Gastroenterology and Hepatology Department of Theodor Bilharz Research Institute, Giza, Egypt. Fifteen wedge liver biopsies, taken during laparoscopic cholecystectomy, were included in the study as normal controls.
