项目摘要

Project Summary Nonalcoholic fatty liver disease (NAFLD) affects over 30% adults in the US. The NAFLD initially manifests as hepatic steatosis and progresses to nonalcoholic steatohepatitis (NASH), fibrosis, and even cirrhosis or hepatocellular carcinoma. Due to the progressive nature of the disease, it is crucial to understand the early pathogenic events of the NAFLD development. Among those early events, abnormal lipid metabolism is largely responsible for the hepatic steatosis that is manifested as extra triglyceride accumulation in the liver in the form of lipid droplets. Triglyceride homeostasis is a very dynamic process as it involves both biosynthesis and breakdown. The lipid droplet mobilization remains poorly understood. In this application, the research team will investigate the regulatory mechanisms of lipid droplet breakdown in cellular and animal models with a focus on a key autophagy regulator – autophagy related 14. It is expected that the proposed research will provide key mechanistic insights into the strategy for therapeutic intervention and treatment of NAFLD.

项目摘要非酒精性脂肪肝病（NAFLD）在美国影响30％以上的成年人。 NAFLD最初表现出来随着肝脂肪变性并发展到非酒精性脂肪性肝炎（NASH），纤维化，甚至是肝硬化或肝细胞癌。由于疾病的渐进性，了解早期至关重要 NAFLD发育的致病事件。在这些早期事件中，异常脂质代谢在很大程度上是负责肝脂肪变性，表现为肝脏在肝脏中的额外甘油三酸酯积累形式脂质液滴。甘油三酸酯稳态是一个非常动态的过程，因为它涉及生物合成和分解。脂质液滴动员仍然很少了解。在此应用程序中，研究团队将研究细胞和动物模型中脂质滴分解的调节机制，重点是一个关键的自噬调节器 - 自噬相关14。预计拟议的研究将提供关键对NAFLD治疗干预和治疗策略的机械洞察力。
