Mitochondrial dysfunction is linked to a range of human pathologies including heritable genetic mitochondrial diseases, complex multigenic human traits, environmental toxicities, nutrition-related conditions, age-related diseases, and aging itself. Mitochondria are the organelles best known for the roles they play in the production of ATP and are often thought of as simply the ‘powerhouse of the cell’. Contrary to this simplified view, mitochondria perform a wide range of critical functions including modulation of nutrient signaling pathways, maintenance of proteostasis, regulation of programmed cell death, calcium buffering, production of reactive oxygen species, and regulation of redox. Mitochondrial dysfunction is a hallmark of aging, and dysregulation of mitochondrial processes plays a major role in many aging-related diseases. The most notable examples are age-related neurodegenerative diseases such as Parkinson’s disease, where mutations in mitochondrial quality control pathways and environmental mitotoxins have been independently causally linked to the disease. The precise mechanistic relationships between individual mitochondria-regulated processes and various age-related diseases, and aging, is an active area of study, with a great deal left to resolve. Given the role of mitochondrial dysfunction in human disease, strategies and agents designed to target mitochondria are of great interest to public health, particularly with respect to age-related diseases.
