Abstract: The concept of cardioprotection through preconditioning against ischemia–reperfusion (I/R) injury is well known and established. However, among different proposed mechanisms regarding the concept of ischemic preconditioning, protein kinase C (PKC)-mediated cardioprotection through ischemic preconditioning plays a key role in myocardial I/R injury. Thus, this study was designed to find the relationship between PKC and sodium glucose transporter 1 (SGLT1) in preconditioning-induced cardioprotection, which is ill reported till now. By applying a multifaceted approach, we demonstrated that PKC activates SGLT1, which curbed oxidative stress and apoptosis against I/R injury. PKC activation enhances cardiac glucose uptake through SGLT1 and seems essential in preventing I/R-induced cardiac injury, indicating a possible cross-talk between PKC and SGLT1.
