Potential relevance to dietary restriction and ageing

Observations

Mutation in chico extends mean, median, and maximum lifespan by 56%, 48%, and 42% in homozygotes and 44%, 36%, and 35% in heterozygotes. chico mutation produces dwarf, long-lived females at normal nutrition. Male heterozygous live 13% longer than wild-type, but male homozygous have a shortened lifespan [188]. Wild-type and chico mutant females have similar peak lifespan under DR, but the food concentration at which these are achieved is shifted to higher amounts. chico mutation induces a state equivalent to submaximal, DR-induced slowing of aging [2576].
