Abstract
AIMS The clinical application of doxorubicin (DOX), a potent anthracycline anticancer drug that effectively treats various malignancies, is limited by its side effects, such as cardiomyopathy. Apurinic/apyrimidinic endonuclease 1/redox factor-1 (APE1/Ref-1) is a multifunctional protein that can be secreted and is a promising target for the reduction of DOX-induced inflammation and oxidative stress. We aimed to investigate the protective role of secretory APE1/Ref-1 against DOX-induced cardiac injury. METHODS AND RESULTS Designated adenoviral preprotrypsin-leading sequence APE1/Ref-1 (Ad-PPTLS-APE1/Ref-1) was used to overexpress secretory APE1/Ref-1 and assess its role in preventing DOX-induced cardiomyopathy in vitro. Our findings revealed that exposure to secretory APE1/Ref-1 significantly decreased N-terminal pro-B-type natriuretic peptide levels in DOX-treated H9C2 cells. In addition, secretory APE1/Ref-1 reduced the severity of cardiomyocyte injury and apoptosis in both in vitro and in vivo DOX-induced cardiotoxicity models. The observed cardioprotective effects of secretory APE1/Ref-1 were mediated via inhibition of the p53 signalling pathway and enhancement of cell viability through attenuation of oxidative stress in DOX-treated cardiomyocytes. CONCLUSIONS Our study provides evidence that secretory APE1/Ref-1 has the potential to inhibit DOX-induced cardiac toxicity by inhibiting oxidative stress and p53 related apoptosis both in vitro and in vivo. These findings suggest that secretory APE1/Ref-1 supplementation is a promising strategy to attenuate DOX-induced cardiomyocyte damage in a preclinical model. Further clinical investigations are essential to validate the therapeutic efficacy and safety of the intervention in human subjects.
