Project description:Hepatitis C Virus (HCV) core protein plays a major role in HCV mediated liver pathologies. We have previously reported that HCV core variants isolated from tumoral (T) and non-tumoral (NT) livers were capable to alleviate Smad transcriptional activity and to shift TGF-β responses from tumor suppressor effects to tumor promotion. To comprehensively appreciate the consequences of core-mediated deregulation of Smad signaling on TGF-b target gene expression, Affimetrix microarrays were performed. Microarray analyses demonstrate that HCV core expression in hepatocytes modulates TGF-b target gene expression. Furthermore, most of the genes modulated in core expressing hepatocytes after TGF-b treatment were already regulated in these non treated cells suggesting that HCV core is capable to activate latent TGF-b. Transcriptome analysis was performed on primary hepatocytes from transgenic mice expressing either Core T or core NT or their control littermates treated or not with TGF-b.

Project description:A quantitative label-free proteome analysis was performed using plasma samples from 22 hepatitis-C virus (HCV)-induced liver cirrhosis patients, 16 HCV-positive hepatocellular carcinoma patients with underlying cirrhosis and 18 healthy controls. Plasma microparticles (PMPS) were isolated using ultracentrifugation and analyzed via label-free LC-MS/MS.

Project description:The hepatitis C virus (HCV) is one of the major risk factors for the development of hepatocellular carcinoma (HCC). Nevertheless, transgenic mice which express the whole HCV polyprotein (HCV-Tg) do not develop HCC. Whereas chronic HCV infection causes inflammation in patients, in HCV-Tg mice, the host immune reaction against viral proteins is lacking. We aimed to test the role of HCV proteins in HCC development on the background of chronic inflammation in vivo. We crossed the HCV-Tg mice which do not produce HCC with the Mdr2-knockout (Mdr2-KO) mice which develop inflammation-associated HCC, to generate Mdr2-KO/HCV-Tg mice. We studied the effect of the HCV transgene on tumor incidence, hepatocyte mitosis and apoptosis, and on gene expression in the liver of produced mice.
