Iled to demonstrate a reduction in infarct size [70, 7] [725]. Although our group lately published a study showing that nonfailing female human hearts have greater protein SNO levels when compared with nonfailing male hearts [26], suggesting achievable relevance to human physiology, many confounding elements may contribute towards the loss of protective mechanisms in the clinical setting, which includes age andor PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/25114510 concurrent pathology. Studies in animal models suggest that cardioprotective signaling is attenuated with aging [7678], which includes the loss of adenosinemediated protection [79]. Several pathological states with the heart similarly abrogate protection. For example, diabetes mellitus has been shown to disrupt cardioprotective signaling, and as such, diabetic hearts cannot be conditioned or cardioprotected [80]. As a result, age and concurrent pathology has the possible to disrupt the protection afforded by adenosine and protein SNO levels in male and female hearts. Due to the fact age andPLOS One https:doi.org0.37journal.pone.07735 May ,9 CHA enhances protein SNO levels and induces cardioprotectionconcurrent pathology are vital when it comes to translating cardioprotective methods towards the clinical setting and most research of cardioprotection are performed with young healthier animals, future research of cardioprotective signaling will have to account for these confounding variables.ConclusionsIn summary, we have demonstrated that activation from the adenosine A receptor increases postischemic functional recovery in both male and female hearts. We discovered that adenosine A receptor activation increases phosphorylated Akt (at ser473) and phosphorylated eNOS (at ser77) levels and enhances the level of SNO proteins in both male and female hearts, likely contributing towards the cardioprotective effects of adenosine A receptor activation. This study has not only demonstrated the protective effects of adenosine A receptor activation in the male and female heart within the setting of IR injury, but also suggests that modifications in protein SNO levels may play a vital role in pharmacologic cardioprotective mechanisms.Supporting informationS Table.
