Moyzis AG, Sadoshima J, Gustafsson ÅB. Mending a broken heart: the role of mitophagy in cardioprotection. Am J Physiol Heart Circ Physiol 308: H183–H192, 2015. First published November 25, 2014; doi:10.1152/ajpheart.00708.2014.—The heart is highly energy dependent with most of its energy provided by mitochondrial oxidative phosphorylation. Mitochondria also play a role in many other essential cellular processes including metabolite synthesis and calcium storage. Therefore, maintaining a functional population of mitochondria is critical for cardiac function. Efficient degradation and replacement of dysfunctional mitochondria ensures cell survival, particularly in terminally differentiated cells such as cardiac myocytes. Mitochondria are eliminated via mitochondrial autophagy or mitophagy. In the heart, mitophagy is an essential housekeeping process and required for cardiac homeostasis. Reduced autophagy and accumulation of impaired mitochondria have been linked to progression of heart failure and aging. In this review, we discuss the pathways that regulate mitophagy in cells and highlight the cardioprotective role of mitophagy in response to stress and aging. We also discuss the therapeutic potential of targeting mitophagy and directions for future investigation.

متن کاملPreconditioning Involves Selective Mitophagy Mediated by Parkin and p62/SQSTM1
Autophagy-dependent mitochondrial turnover in response to cellular stress is necessary for maintaining cellular homeostasis. However, the mechanisms that govern the selective targeting of damaged mitochondria are poorly understood. Parkin, an E3 ubiquitin ligase, has been shown to be essential for the selective clearance of damaged mitochondria. Parkin is expressed in the heart, yet its functio...
متن کاملThe Role of Exercise Preconditioning in Cardioprotection against Ischemia Reperfusion Injury
Cardiovascular diseases are still the main cause of mortality around the world. Therefore, it is essential to develop practical means to reduce their burden. A wealth of evidence supports the role of physical exercise in attenuating many of the risk factors of cardiovascular diseases. Moreover, endurance training warrants protection against myocardial infarction. Exercise, even if performed ...
متن کاملAMPK activation serves a critical role in mitochondria quality control via modulating mitophagy in the heart under chronic hypoxia
Mitochondrial biogenesis is one of the generally accepted regulatory mechanisms in the heart under chronic hypoxia. The precise quantity and quality control of mitochondria is critical for the survival and function of cardiomyocytes. Mitochondrial autophagy, also known as mitophagy, which selectively eliminates dysfunctional and unwanted mitochondria, is the most important type of mitochondrial...
