title: Mitochondrial respiration and reactive oxygen species in C. elegans.
abstract: A powerful approach to understanding complex processes such as aging is to study longevity in organisms that are amenable to genetic dissection. The nematode Caenorhabditis elegans represents a superb model system in which to study the effects of mitochondrial function on longevity. Several mutant strains have been identified that indicate that mitochondrial function is a major factor affecting the organism's lifespan. Taken as a group, these mutant strains indicate that metabolic rate, per se, only affects longevity indirectly. Mutations causing lowered metabolic rate potential are capable of decreasing or increasing longevity.
