SPM pathway marker analysis of the brains of obese mice in the absence and presence of eicosapentaenoic acid ethyl esters.

ABSTRACT: Obesity drives an imbalanced signature of specialized pro-resolving mediators (SPM). Herein, we investigated if high fat diet-induced obesity dysregulates the concentration of SPM intermediates in the brains of C57BL/6 J mice. Furthermore, given the benefits of EPA for cardiometabolic diseases, major depression, and cognition, we probed the effect of an EPA supplemented high fat diet on brain SPM intermediates. Mass spectrometry revealed no effect of the high fat diet on PUFA-derived brain metabolites. EPA also did not have an effect on most brain PUFA-derived metabolites except an increase of 12-hydroxyeicosapentaenoic acid (12-HEPE). In contrast, EPA dramatically increased serum HEPEs and lowered several PUFA-derived metabolites. Finally, untargeted mass spectrometry showed no effects of
