PROJECT SUMMARY Both alcoholic and non-alcoholic fatty liver diseases (AFLD and NAFLD, respectively) cause serious health problems in the US. AFLD occurs in nearly all excessive alcohol drinkers and NAFLD afflicts approximately one-third of adult population. Worse yet, there is no effective treatment for either AFLD or NAFLD at this time. In this proposed research, we plan to investigate molecular mechanisms of Sestrin3 (Sesn3) in the regulation of hepatic lipid metabolism. There are two specific aims in this project. Aim# 1 is to determine the protective mechanism of Sesn3 against AFLD and NAFLD through the Atg14-regulated autophagy pathway. Aim #2 is to examine the role of Sesn3-mTORC2 pathway in the pathogenesis of AFLD and NAFLD. It is anticipated that the findings from this proposed research should provide valuable information for therapeutic development to treat AFLD and NAFLD.

项目摘要 酒精性和非酒精性脂肪性肝病（分别为AFLD和NAFLD）均会导致 美国的严重健康问题。几乎所有过量饮酒者和NAFLD都会发生AFLD 约占成年人口的三分之一。更糟糕的是，这两种疾病都没有有效的治疗方法 此时的AFLD或NAFLD。在这项拟议的研究中，我们计划研究分子机制 Sestrin 3（Sesn 3）在调节肝脏脂质代谢中的作用。这有两个具体的目的 项目目的#1是确定Sesn 3对AFLD和NAFLD的保护机制， Atg 14调节的自噬途径。目的#2是检查Sesn 3-mT 0 RC 2途径在肿瘤细胞中的作用。 AFLD和NAFLD的发病机制。预计这项拟议研究的结果 为AFLD和NAFLD的治疗提供了有价值的信息。
