Our quantitative ELISA assays demonstrated H-FABP as a sensitive and reliable biomarker for measuring cardiomyocyte damage induced by lipopolysaccharide (LPS) and healing by RvE1, a specialized pro-resolving mediator (SPM) derived from the Omega-3 fatty acid, eicosapentaenoic acid (EPA), a dietary nutrient that balances inflammation to restore homeostasis. RvE1 reduced leakage of H-FABP by up to 86%, which supports our hypothesis that inflammation as a mechanism of injury can be targeted for therapy.
