Effect of Mitochondrial Autophagy in Clinical Diseases and Intervention by Chinese Medicine： A Review / 中国实验方剂学杂志

ABSTRACT

Mitochondrial autophagy is a process to clear dysfunctional mitochondria in the cytoplasm to maintain the integrity of mitochondrial function and cell homeostasis. Mitochondrial autophagy is a complex physiological process， which can maintain the balance of mitochondrial quality and quantity， cell survival under starvation and harsh conditions， and the stability of the intracellular environment. Its molecular mechanism involves a variety of proteins. Many factors can induce mitochondrial autophagy， such as starvation， oxidative stress， hypoxia， depolarization， and other stresses. The accumulation of unfolded proteins can also induce mitochondrial autophagy. In recent years， as a research hotspot， the abnormality of mitochondrial morphology and function is closely related to the occurrence of a variety of diseases. The research on mitochondrial autophagy and the pathogenesis of clinical diseases has attracted more attention， such as tumors， cardiovascular diseases， liver diseases， nervous system diseases， and glucose metabolism disorders. It has been found that regulating mitochondrial autophagy may inspire the treatment of some diseases. Meanwhile， clinical researchers have paid more attention to traditional Chinese medicine （TCM）. As revealed by in-depth research， Chinese medicine has a certain value in regulating mitochondrial autophagy. The research on the pathogenesis of mitochondrial autophagy in related diseases and the intervention of Chinese medicine has found that there are many reports on the regulation of mitochondrial autophagy by Chinese medicine in tumors， cardiovascular diseases， and nervous system diseases. However， the mechanism of mitochondrial autophagy， the balance of mitochondrial autophagy， and the difference in the activation or inhibition of mitochondrial autophagy by Chinese medicine remain unclear. The regulation of mitochondrial autophagy has become a new research target strategy of Chinese medicine in the prevention and treatment of diseases. This paper reviewed the available literature in recent years to provide reference materials for the regulation of mitochondrial autophagy by Chinese medicine and ideas for the follow-up research of Chinese medicine in mitochondrial autophagy.
