项目摘要

DESCRIPTION (provided by applicant): Hepatitis C virus (HCV) often causes persistent infection in humans, which may lead to progressive liver disease. We hypothesize that disease progression from chronic HCV infection is attributed, at least in part, to the effect of HCV core protein on the expression of host cellular genes. Our long term goal is to understand the underlying mechanisms behind HCV mediated liver disease progression. We were among the first to identify many intriguing functions related to HCV core protein, which may significantly contribute to disease progression. However, there are critical gaps in our understanding of the key cellular targets and molecular mechanisms by which core protein exerts these functions alone or in context to other HCV proteins. HCV induces hepatocellular insulin resistance and hepatic fibrogenesis. Our focus in this grant application is to examine the underlying mechanisms of HCV induced insulin resistance and fibrogenesis as a follow up to our preliminary data provided with this application. The current research proposal includes complementary but independent aims to address our hypothesis. Aim 1 will investigate the mechanism of IRS phosphorylation by HCV core protein, Aim 2 will investigate the functional correlates of HCV core protein induced metabolic regulators, and Aim 3 will evaluate the role of HCV core protein in hepatic fibrosis. Studies will also be performed using full-length cDNA, replicon or cell culture grown HCV to provide a molecular basis for HCV core protein functions in context to other HCV proteins. Knowledge on the molecular determinants involved in HCV mediated disease progression will open avenues for novel therapeutic approach. PUBLIC HEALTH RELEVANCE: Hepatitis C virus (HCV) often causes persistent infection and progressive liver disease. We plan to understand the molecular determinants involved in HCV mediated liver disease progression, which will open avenues for novel therapeutic approach.
描述(申请人提供):丙型肝炎病毒(丙型肝炎病毒)通常会导致人类持续感染,这可能会导致进行性肝病。我们假设慢性丙型肝炎病毒感染的疾病进展至少部分归因于丙型肝炎病毒核心蛋白对宿主细胞基因表达的影响。我们的长期目标是了解丙型肝炎病毒介导的肝病进展背后的潜在机制。我们是首批确定与丙型肝炎病毒核心蛋白相关的许多有趣功能的人之一,这些功能可能显著促进疾病的进展。然而,在我们对核心蛋白单独或与其他丙型肝炎病毒蛋白协同发挥这些功能的关键细胞靶点和分子机制的理解上存在着严重的差距。丙型肝炎病毒可诱导肝细胞胰岛素抵抗和肝纤维化。我们在这项赠款申请中的重点是研究丙型肝炎病毒诱导的胰岛素抵抗和纤维化的潜在机制,作为对我们提供的初步数据的后续研究。目前的研究提案包括补充但独立的目的,以解决我们的假设。目的1研究丙型肝炎病毒核心蛋白对IRS的磷酸化机制,目的2研究丙型肝炎病毒核心蛋白诱导的代谢调节的功能相关性,目的3评价丙型肝炎病毒核心蛋白在肝纤维化中的作用。研究还将使用全长cDNA、复制子或细胞培养生长的丙型肝炎病毒,以提供与其他丙型肝炎病毒蛋白相关的丙型肝炎病毒核心蛋白功能的分子基础。了解涉及丙型肝炎病毒介导的疾病进展的分子决定因素将为新的治疗方法开辟道路。公共卫生相关性:丙型肝炎病毒(丙型肝炎病毒)通常会导致持续性感染和进行性肝病。我们计划了解与丙型肝炎病毒介导的肝病进展有关的分子决定因素,这将为新的治疗方法开辟道路。
