Canagliflozin reverses doxorubicin-induced cardiotoxicity via restoration of autophagic homeostasis.

Sodium-glucose cotransporter 2 inhibitors (SGLT2i) have been reported as successful for preventing doxorubicin (DOX) -induced cardiotoxicity (DIC), but the underlying mechanisms are elusive. This study aimed to determine whether canagliflozin, an SGLT2i, protects against DIC by regulation of autophagic flux in cardiomyocytes through a mechanism independent of SGLT2. The differentially expressed autophagy-related genes (ARGs) in DIC were analyzed.
