The role of mitochondrial fusion and fission in the process of cardiac oxidative stress.

The role of mitochondrial fusion and fission in the process of cardiac oxidative stress. Histol Histopathol. 2019 Dec 10;:18191 Authors: Yu F, Abdelwahid E, Xu T, Hu L, Wang M, Li Y, Mogharbel BF, de Carvalho KAT, Guarita-Souza LC, An Y, Li P Abstract Mitochondria are the energy suppliers in the cell and undergo constant fusion and fission to meet metabolic demand during the cell life cycle. Well-balanced mitochondrial dynamics are extremely important and necessary for cell survival as well as for tissue homeostasis. Cardiomyocytes contain large numbers of mitochondria to satisfy the high energy demand. It has been established that deregulated processes of mitochondrial dynamics play a major role in myocardial cell death. Currently, cardiac mitochondrial cell death pathways attract great attention in the cell biology and regenerative medicine fields. Importantly, mitochondrial dynamics are tightly linked to oxidative stress-induced cardiac damage. This review summarizes molecular mechanisms of mitochondrial fusion and fission processes and their potential roles in myocardial cell death triggered by oxidative stress. Advances in understanding the contribution of both normal and abnormal mitochondrial dynamics to heart protection will lead to significant improvement of therapeutic discoveries.
