Research Interests

Obesity and its associated health comorbidities are a worldwide epidemic with serious economic and health burden on society. Adipose tissue is an important endocrine organ that plays a key role in the development of obesity and various metabolic disorders. White adipocytes store excess energy in the form of triglycerides for future need. By contrast, brown and beige (browning-in-white) adipocytes metabolize lipid and glucose to produce heat in a process known as nonshivering thermogenesis, which is crucial in systemic energy homeostasis and thermoregulation. Functional brown and beige adipose tissues are highly correlated with body mass index in adult humans and is either reduced or absent in obese and aged individuals and rodents. The long-term research interest in the lab is to understand the regulation of white, beige and brown adipose tissue development and energy homeostasis, and use it to develop potential therapeutic approaches for obesity and related metabolic diseases. 


Current Projects

Current projects focus on identifying the function of a gene called BSCL2 in regulating the development and metabolic action of white, beige and brown adipose tissues. Mutations in human BSCL2 gene have been associated with type 2 Berardinelli-Seip Congenital Lipodystrophy (BSCL2), an autosomal recessive disease characterized by a near total absence of body fat from birth or early infancy. We have created animal models with which BSCl2 is deleted embryonically, or in a fat or brown fat specific manner, or only in mature white or brown adipocytes to study the crucial role of BSCL2 in controlling differentiation, metabolism and turnover of adipocytes. We also utilize a wide array of molecular, cellular, biochemical and metabolic approaches to identify the direct targets of BSCL2 and the mechanisms underlying the development of metabolic disorders in mice with adipose tissue dysfunction.
