Metabolism of Omega-3 fatty acids and Endocannabinoids by CYP epoxygenases to yield Anti-Inflammatory Lipid Metabolites

Our laboratory focuses on understanding how dietary fatty acids gets converted to anti-inflammatory lipid signaling molecules by epoxygenases.

Research in our laboratory is highly interdisciplinary and collaborative.

Mechanisms of Eicosanoid Synthesizing Enzymes

 Metabolism of Omega-3 and Omega-6 fatty acids by epoxygenases in the heart

Dietary consumption of omega-3 and omega-6 fatty acids have been linked to cardiovascular health benefits in humans. The central hypothesis is that the cardiovascular physiological effects of omega-3 and omega-6 fatty acids are partly mediated by the synthesis of eicosanoids via the epoxygenase (EPOX) pathway and also via reduction of platelet aggregation. The goal is to provide support to this central hypothesis through biochemical and physiological studies. 

 

Novel Endocannabinoid Epoxide Metabolites

Omega-3 and omega-6 endocannabinoids ellicit similar response to Cannabis in the body. Our lab is studying the metabolism of these endocannabinoids through the epoxygenase pathway.
