Abstract:
Aging is characterized by a progressive decline in cellular function, organismal fitness and increased risk of age-associated diseases and death. One potential cause of aging is the progressive accumulation of dysfunctional mitochondria and oxidative damage with age. Considerable efforts have been made in our understanding of the role of mitochondrial dysfunction and oxidative stress in aging and age-associated diseases. This chapter outlines the interplay between oxidative stress and mitochondrial dysfunction, and discusses their impact on senescence, cell death, stem cell function, age-associated diseases and longevity.

The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
