The heart’s tolerance to ischemia–reperfusion injury varies according to a day–night cycle. Vinod et al. show that a timed low dose of cardiac glycosides, such as digoxin, is protective against heart ischemia–reperfusion injury by promoting the proteasomal degradation of the molecular-clock component and transrepressive nuclear receptor REV-ERBα.
