研究概述/Research Description

  胆固醇是生命活动必需的脂类物质,并与心血管疾病、神经退行性疾病及肿瘤等的发生密切相关,胆固醇代谢是生命医学的前沿领域和药物研发的关键基础。我们长期从事胆固醇代谢研究,取得如下成果:1.阐明小肠胆固醇吸收途径并鉴定一系列蛋白,包括从低血脂家系中发现新调控基因LIMA1。2.阐明一条胆固醇合成负反馈调控途径,即HMGCR降解机制,发现内源信号分子、E3、共因子及营养感知机制,发现USP20是饥饿—进食转化中控制胆固醇合成的关键蛋白。3.发现一细胞内胆固醇运输新途径,即过氧化物酶体—溶酶体—内质网通过膜接触介导转运。4.发现胆固醇共价修饰SMO蛋白,调控信号转导和发育。5.揭示通过抑制糖蛋白受体ASGR1而促进胆固醇外排的通路。这些成果引领胆固醇领域的发展,并对降脂新药研发有重要意义。在Nature (2)、Science、Cell等期刊发表论文60多篇,成果被选入多部经典教材。

Bao-Liang Song’s lab focuses on cholesterol metabolism. 1) He illustrates the molecular pathway of intestinal cholesterol absorption. He finds that NPC1L1 and Flotillins form cholesterol-rich microdomains in the plasma membrane (PM) (PNAS, 2011). Cholesterol binds to the N-terminal domain of NPC1L1, releasing its C-terminal tail from PM and recruiting the clathrin adaptor NUMB to initiate endocytosis (Nature Medicine, 2014). The cholesterol absorption inhibitor ezetimibe blocks cholesterol uptake by impairing NPC1L1 endocytosis (Cell Metab, 2008). He identifies LIMA1 through human genetic study and shows LIMA1 bridges NPC1L1 to Myosin Vb and transports NPC1L1 back to the PM (Science, 2018). 2) He delineates the molecular pathway of sterol-induced degradation of HMGCR, a rate-limiting enzyme in cholesterol biosynthesis. He identifies gp78 and RNF145 as the E3s (Mol Cell, 2005; Cell Metab, 2012), lanosterol as the endogenous regulator (Cell Metab, 2005; Cell Metab, 2011; JLR, 2019) and Ufd1 as a cofactor of gp78 (Cell Metab, 2007). Recently, he finds that USP20 is the key protein controlling cholesterol biosynthesis in the starvation-feeding transition state (Nature, 2020). 3) He finds that cholesterol is transported through lysosome-peroxisome membrane contacts (Cell, 2015). Peroxisomal cholesterol is further delivered to the ER through membrane contacts. 4) He finds that cholesterol covalently modifies the SMO protein through a Ca2+-boosted autoreaction, demonstrating cholesterol can function as a covalent ligand to regulate Hedgehog signaling and embryonic development (Mol Cell, 2017; Cell Res, 2022). 5) He recently finds a pathway to promote cholesterol excretion through inhibiting ASGR1 (Nature 2022). His pioneer work has significant impact on the cholesterol field and sheds new light on cholesterol-lowering drug development. As the corresponding author, he has published more than 60 papers including Nature (2), Science, and Cell papers. His work has been included in several classic textbooks such as Lehninger Principles of Biochemistry.
