Clinical/Research Interests:

The research in my laboratory primarily focuses on understanding the mechanisms that regulate nutrient and energy metabolism, and how they become reprogrammed in obesity, lipodystrophy, and cardiometabolic diseases. We are specifically interested in the following areas: (1) Adipose biology and energy balance in obesity and lipodystrophy; (2) Cardiac substrate utilization in heart failure; (3) Lipid metabolism in liver pathophysiology. Using in vitro molecular/cellular biology approaches, a combination of genomics, transcriptomics, proteomics, CRISP/Cas9-mediated genome editing, and state-of-the-art in vivo mouse physiology analyses, we aim to define the pathological alterations of metabolic communication in diseases including obesity, diabetes, and their associated liver and heart diseases. Ultimately, we aim to identify targets and design therapeutics for these diseases.

1. Adipose tissue development in obesity and lipodystrophy.

Obesity is a global epidemic with serious health and economic burdens. Adipose tissue acts as an endocrine organ, crucial in obesity and metabolic disorders. White adipocytes store triglycerides, while brown and beige adipocytes produce heat through nonshivering thermogenesis, essential for energy balance. We developed lipodystrophic Bscl2 knockout mice, revealing its role in adipose maintenance and associated health issues. Our research focuses on molecular functions of posttranslational modifications and GWAS-identified genes in adipose development, obesity, and lipodystrophy.

2. Lipid metabolism in metabolic cardiomyopathy.

Metabolic disruptions underlie many cardiomyopathies. In healthy humans, fatty acid oxidation supplies 60-70% of myocardial energy. In obesity and diabetes, increased FA supply raises FA oxidation, reducing efficiency and causing lipotoxicity. Heart triglycerides (TGs) provide FAs and regulate heart function. We showed BSCL2's essential role in cardiac substrate use and function. We aim to better understand the mechanisms of cardiac TG lipolysis, mitochondrial function, and metabolic cardiomyopathy.

3. Liver pathophysiology in obesity and diabetes.

Metabolic dysfunction-associated steatotic liver disease (MASLD) spans from simple fat accumulation in the liver to Metabolic Dysfunction-Associated Steatohepatitis (MASH), which involves inflammation and increasing fibrosis, possibly resulting in cirrhosis and liver failure. MASLD affects up to 70% of individuals with T2D. Those with diabetes are at significantly higher risk of developing MASH, cirrhosis, and hepatocellular carcinoma. Current treatment options are limited due to a poor understanding of the molecular processes behind MASLD and MASH. Our research highlights the crucial role of NAE1-mediated neddylation in liver development and function. We aim to identify new factors that contribute to liver diseases in obesity and diabetes.
