苏文博士的研究方向长期聚焦于“脂滴及脂滴蛋白在脂代谢和代谢性疾病中的作用及机制研究”。她纯化并建立了人肝脏脂滴相关蛋白谱,并确认了一系列在人非酒精性脂肪性肝病(NAFLD)中变化的脂滴相关蛋白。她确认其中一个肝脏特异性脂滴蛋白17β-HSD13是NALFD发病的致病因子(2014, 111 (31):11437, PNAS)。从她加入深大后,她开展了一系列相关研究,包括:(1) 利用多种基因工程小鼠展开17β-HSD13的功能学研究; (2) 阐明急性和慢性肝损伤中脂代谢紊乱的机制; (3)筛选17β-HSD13,FXR,LXR为靶点的脂肪肝治疗药物. 苏文博士的原创性研究为脂肪肝治疗提供了新的潜在靶点并被新英格兰杂志在大规模人群上验证。她发现体内、外过表达17β-HSD13均能增加脂滴的大小和蓄积,其机制是通过调控SREBP-1c的成熟。苏文博士目前已有发明专利2项,构建了多种转基因工程小鼠。她接下来的五年研究计划为1.确认多种基因工程小鼠的代谢表型;2. 结合多种NASH(脂肪性肝炎)动物模型明确17β-HSD13在NAFLD整个发病过程中的作用; 3. 利用生化、脂质组、代谢组手段明确17β-HSD13的细胞生理学功能;4. 在细胞侧面研究17β-HSD13在脂滴新生、成熟、融合和降解及翻译后修饰过程中的精确调控机制,苏文博士目前H-index指数为17。 |

Dr.Su has been focusing on the field “lipid droplet, lipid droplet proteins, dysregulation of lipid metabolism and metabolic diseases” for a long time with a series work. She purified and established human liver LD-associated proteome and identified an array of proteins differentially expressed in human NALFD. She demonstrated a liver-specific LD protein 17βHSD13 as a pathogenic factor and drug target of NAFLD (2014, 111 (31):11437, PNAS). Since joining Shenzhen University, she carried out several related studies, including: (1) Function study of 17β-HSD13 by using various hsd17b13 (the gene codes 17β-HSD13) genetic edited mice and biochemistry methods; (2) Elucidate the mechanism of lipid dysregulation in acute and chronic liver diseases; (3) Screen of lead compounds that targets 17β-HSD13, FXR, LXR for NAFLD treatment. Dr Su’s original research about 17β-HSD13 provides a potential link between LD proteins and NAFLD, and has been cited by more than 120 papers including papers on NEJM, hepatology, journal of hepatology and so on. She found over-expression of 17β-HSD13 in vivo and in vitro increases size and accumulation of lipid droplets in hepatocytes, which possible mechanism is through enhancement of lipogenesis and maturation of SREBP-1c. Her subsequent work demonstrated 17β-HSD13 was regulated by LXRα agonist T0901317 via a SREBP-1c dependent mechanism (2017, 312(4), Am J Physiol Endocrinol Metab.;2018, 67(supplement 1), Diabetes). She proposed the possible regulation mechanism of 17β-HSD13 and SREBP-1c, and suggested 17β-HSD13 as a potent NASH target (2019, 489:119-125, Mol Cell Enocrinol.). She has 2 patents on 17β-HSD13 and NAFLD drug target. She now successfully constructed 17β-HSD13 liverspecific transgenic, knockout, liver-specific knockout, and two key amino site mutant mice lines, and also a various of HSD17B13 associated plasmid. Her next 5 year-plan include: 1. Define the metabolic phenotypes of those genetically engineered mice; 2. Determine the pathophysiological role of 17βHSD13 during different stages of NAFLD from benign steatosis, NASH to HCC via challenging highfat diet (short term and long term), MCD, and FPC models; 3. Characterize the biological function of 17β-HSD13 by using biochemical, lipidomic, and metabolomic approaches; 4. Study the role 17β-HSD13 in regulating LD generation, growth, fuse, and degradation and the post-translational modification of 17βHSD13. In terms of paper publication and academic effect. Dr.Su’s h-index is 17. |
