Potential relevance to the human ageing process

Main reason for selection
Entry selected based on evidence directly linking the gene product to ageing in a non-mammalian animal model
Description

Catalase is an antioxidant that protects cells from hydrogen peroxide. Some experiments in invertebrates suggest a role for CAT in ageing. Overexpression of CAT and SOD1 in short-lived strains of fruit flies extends lifespan and appears to delay ageing [39], but the same effects are not witnessed in long-lived strains [40]. CAT overexpression targeted to mitochondria extends longevity in mice, but this appears to be related to a lower incidence of cardiac pathology rather than delayed ageing [1335]. These mutants are also more resistant to age-related skeletal muscle dysfunction and exhibit improved voluntary exercise, increased muscle force, decreased intracellular Ca(2+) leak and increased sarcoplasmic reticulum Ca(2+) load [3638]. Cardiac-specific overexpression prolongs lifespan in mice [1941]. Although it has been argued that CAT plays a role in ageing, there is no direct evidence linking CAT to human ageing.
