For the treatment of heart failure, controlling cardiac remodeling is very important. In recent years, clinical trials have shown that sodium-glucose cotransporter-2 (SGLT-2) inhibitors not only excel in lowering glucose levels but also demonstrate favorable cardiovascular protective effects. However, the precise mechanisms behind the cardiovascular benefits of SGLT-2 inhibitors remain elusive. In this research, we assessed the impact of canagliflozin (CANA, an SGLT-2 inhibitor) on cardiac remodeling progression in mice and preliminarily elucidated the possible mechanism of action of the SGLT-2 inhibitor. Our results indicate that the administration of canagliflozin significantly attenuates myocardial hypertrophy and fibrosis and enhances cardiac ejection function in mice with isoprenaline (ISO)-induced cardiac remodeling. Notably, excessive mitophagy, along with mitochondrial structural abnormalities observed in ISO-induced cardiac remodeling, was mitigated by canagliflozin treatment, thereby attenuating cardiac remodeling progression. Furthermore, the differential expression of AMPK/PINK1/Parkin pathway-related proteins in ISO-induced cardiac remodeling was effectively reversed by canagliflozin, suggesting the therapeutic potential of targeting this pathway with the drug. Thus, our study indicates that canagliflozin holds promise in mitigating cardiac injury, enhancing cardiac function, and potentially exerting cardioprotective effects by modulating mitochondrial function and mitophagy through the AMPK/PINK1/Parkin pathway.</p>","PeriodicalId":15212,"journal":{"name":"Journal of Cardiovascular Pharmacology","volume":" ","pages":"496-505"},"PeriodicalIF":2.6,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141988074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the regulatory effects and associated mechanisms of kirenol in myocardial ischemia/reperfusion injury (MI/RI) remain unclear. In this study, first, the MI/RI rat model was established. It was demonstrated that kirenol protected against the aggravation of cardiac function in MI/RI rats. In addition, the inflammation was induced by ischemia reperfusion (IR), which was likewise affected by kirenol (5 or 10 mg/kg). Moreover, IR enhanced oxidative stress, a process that was counteracted by kirenol. Next, cell apoptosis was discovered to be heightened after IR, but this effect was neutralized by kirenol. Finally, it was revealed that kirenol has the ability to block the activation of the NF-κB pathway. In conclusion, it was disclosed that kirenol alleviated inflammation and oxidative stress through modulating the NF-κB pathway to improve MI/RI in rats.
