Aging as a mitochondria-mediated atavistic program: can aging be switched off?

Abstract excerpt

Programmed death phenomena have been demonstrated on subcellular (mitoptosis), cellular (apoptosis), and supracellular (collective apoptosis) levels. There are numerous examples of suicide mechanisms at the organismal level (phenoptosis). In yeast, it was recently shown that the death of aging cells is programmed.
