Background
Mitochondrial calcium overload and oxidative stress during ischemia reperfusion (I/R) injury remains a major obstacle during percutaneous coronary intervention after acute myocardial infarction. It often leads to an increased susceptibility for mitochondria permeability transition pore (mPTP) opening leading to cell death. Mitochondrial calcium overload and ROS have been identified as key triggers to open the mPTP for over 30 years, yet the exact mechanism has remained elusive. Additionally, glycogen synthase kinase 3β; (GSK-3β;) is proposed as one of the key molecules that regulate mitochondrial dysfunction and injury during I/R. Indeed inhibition of GSK-3β has been shown to be required …
