My research focuses on deciphering the roles and underlying mechanisms of adipocyte or liver-derived hormones such as adiponectin, fibroblast growth factor-1 (FGF21) and adipocyte fatty acid binding protein (A-FABP) in the regulation of energy metabolism and in the pathogenesis of obesity-related cardio-metabolic and inflammatory diseases such as type-2 diabetes, atherosclerosis and non-alcoholic fatty liver disease. My team discovered that pharmacological inhibition of A-FABP can significantly alleviate the development of both acute liver injury and non-alcoholic fatty liver disease in mice and A-FABP mediates these diseases by enhancing inflammation in Kupffer cells. A-FABP is also a mediator of myocardial ischemia/reperfusion injury and diabetes-induced cardiac dysfunction through its suppression on eNOS/NO pathway and induction of superoxide anion production. We also demonstrated that A-FABP potentiates toxic lipids-induced endoplasmic reticulum and inflammation in macrophages via inhibition of Janus Kinase 2-dependent autophagy. My team discovered the physiological role of A-FABP in energy metabolism which regulates adaptive thermogenesis through promoting the intracellular conversion of thyroid hormone T4 to T3 in brown adipocytes. The study result implicated that global pharmacological inhibition of A-FABP may not be an optimal therapeutic strategy for obesity-related cardiovascular and metabolic diseases due to the potential impairment of adaptive thermogenesis.
Dr. Ruby L.C. Hoo obtained her Bachelor, MPhil and PhD in biological science at The University of Hong Kong.
