The role of mitochondrial dynamics in human cancers.
Yawen Ma, Lihua Wang, Renbing Jia
Abstract
Mitochondria are crucial cellular organelles. Under extracellular stimulations, mitochondria undergo constant fusion and fission dynamics to meet different cellular demands. Mitochondrial dynamics is regulated by specialized proteins and lipids. Dysregulated mitochondrial dynamics has been linked to the initiation and progression of diverse human cancers, affecting aspects such as cancer metastasis, drug resistance and cancer stem cell survival, suggesting that targeting mitochondrial dynamics is a potential therapeutic strategy. In the present review, we summarize the molecular mechanisms underlying fusion and fission dynamics and discuss the effects of mitochondrial dynamics on the development of human cancers.
