Dr. Mengwei Zang is a faculty member in the Sam and Ann Barshop Institute for Longevity and Aging as well as the Department of Molecular Medicine. The Zang lab focuses on the molecular mechanisms underlying obesity, diabetes and chronic liver disease related to aging.

Zang lab seeks to develop new therapeutic strategies for obesity, diabetes, and fatty liver disease by building a better understanding of molecular mechanisms of nutrient sensing network. Studies from Zang laboratory have identified several nutrient sensors, such as AMP-activated protein kinase (AMPK), the NAD-dependent deacetylase (SIRT1), mechanistic target of rapamycin (mTOR), and the hepatocyte-derived hormone FGF21. Dysregulation of AMPK or SIRT1 signaling appears to be involved in the pathogenesis of fatty liver disease and adipose tissue fibrosis in obesity and type 2 diabetes. Zang Lab has also elucidated AMPK-dependent inhibition of de novo lipogenesis as a molecular mechanism for the beneficial effects of metformin, the most widely prescribed type 2 diabetes drugs, and polyphenols, on hepatic steatosis, hyperlipidemia, and atherogenesis in type 1 and type 2 diabetes. Further studies demonstrated that SIRT1 is functionally linked to FGF21 and the regulation of fatty acid metabolism, providing major therapeutic targets for the treatment of fatty liver disease. These important findings were published in high impact journals such as Cell Metabolism, Gastroenterology, Hepatology, and Diabetes.

Zang Lab’s research utilizes a variety of biochemical, cellular biology, metabolic and screening approaches both in cell culture and whole animals to identify the molecular mechanisms by which mammalian cells sense, communicate, and respond to nutrients. The ultimate goal is to provide new insight into the pathological mechanisms of diabetes and obesity as well as to identify potential therapeutic interventions of metabolic disease and age-associated metabolic diseases.

    Grants

     

    Federal

     

    Funding Agency NIH/NIDDK

    Title: Hepatokine Control of Metabolic Crosstalk and Insulin Resistance

    The major goal of this project is to understand how the NAD+-dependent deacetylase SIRT1 regulates hepatokines that are secreted by the liver and whether this process affects the progression of non-alcoholic fatty liver disease and diabetes.

     

    Funding Agency NIH/NIAAA

    Title: Alcohol-induced Dysregulation of Thiol Homeostasis and Endothelial Function

    The major goal of this study is to investigate whether Glutaredoxin-1, a specific de-glutathionylation thioreductase, controls redox hemostasis and improves chronic alcohol-induced endothelial dysfunction.

     

    Funding Agency NIH/NIDDK

    Title: Retinoic Acid receptor, Lipid Metabolism, and Fatty Liver Disease

    The overall objective of this project is to define the metabolic consequence, intervention, and mechanism of vitamin A-related retinoic acid receptor on non-alcoholic fatty liver disease (NAFLD),one of the most common chronic liver diseases in the United States.

     

    Funding Agency American Diabetes Association

    Title: Retinoic Acid Receptor Functions as a Novel Regulator of Lipid Metabolism in Diabetes

    The major goal of this ADA Basic Science Award is to investigate the effect of retinoic acid receptor on whole-body energy balance and insulin resistance in diabetes and obesity, a major public health issue in more than one-third adults (over 72 million people) in the United States.
