The role of mitochondria in cellular senescence
Shohini K. Ghosh‐Choudhary, Jie Liu, Toren Finkel
Abstract
Mitochondria are intimately connected to cell fate and function. Here, we review how these intracellular organelles participate in the induction and maintenance of the senescent state. In particular, we discuss how alterations in mitochondrial metabolism, quality control and dynamics are all involved in various aspects of cellular senescence. Together, these observations suggest that mitochondria are active participants and are mechanistically linked to the unique biology of senescence. We further describe how these insights can be potentially exploited for therapeutic benefit.
