For common SNO proteins that have been identified in male and female hearts, SNO levels were assessed via labelfree peptide quantification for (A) aconitase, (B) electron transfer flavoprotein , (C) lactate dehydrogenase, (D) voltagedependent anion channel two, (E) voltagedependent anion channel 3, (F) isocitrate dehydrogenase , (G) enoylCoA hydratase, and (H) sarcoplasmic reticulum Ca2ATPase 2a (male manage: clear bar, male CHA: clear hashed bar, female handle: black bar, female CHA: black hashed bar).

Constant using a previous study in rat heart mitochondria [35], we located that postischemic ROS production was considerably decreased in female hearts in comparison to male hearts (Fig 8a). Interestingly, we discovered that dihydrolipoyl dehydrogenase was uniquely SNOmodified within the female heart. Dihydrolipoyl dehydrogenase is a MedChemExpress Isorhamnetin component of the alphaKGDH complicated, which is thought of to be a major source for the production of ROS [368]. Consequently, we subsequent examined the effect of SNO around the ROS production on the alphaKGDH complex utilizing an in vitro assay with purified enzyme. Following a 30.
