TRIM63 and cardiomyopathy: With PPAR signaling at the center of regulating fatty acid oxidation and mediating the pathogenesis of type 2 DM induced cardiomyopathy, we hypothesized that if MuRF2−/− hearts had enhanced PPAR signaling, they would undergo an accelerated cardiomyopathy due to MuRF2’s direct regulation of PPAR activity.
