About: Age-1

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The age-1 gene is located on chromosome 2 in C.elegans. It gained attention in 1983 for its ability to induce long-lived C. elegans mutants. The age-1 mutant, first identified by Michael Klass, was reported to extend mean lifespan by over 50% at 25 °C when compared to the wild type worm (N2) in 1987 by Johnson et al. Development, metabolism, lifespan, among other processes have been associated with age-1 expression. The age-1 gene is known to share a genetic pathway with daf-2 gene that regulates lifespan in worms. Additionally, both age-1 and daf-2 mutants are dependent on daf-16 and daf-18 genes to promote lifespan extension.

  • The age-1 gene is located on chromosome 2 in C.elegans. It gained attention in 1983 for its ability to induce long-lived C. elegans mutants. The age-1 mutant, first identified by Michael Klass, was reported to extend mean lifespan by over 50% at 25 °C when compared to the wild type worm (N2) in 1987 by Johnson et al. Development, metabolism, lifespan, among other processes have been associated with age-1 expression. The age-1 gene is known to share a genetic pathway with daf-2 gene that regulates lifespan in worms. Additionally, both age-1 and daf-2 mutants are dependent on daf-16 and daf-18 genes to promote lifespan extension. Long-lived age-1 mutants are resistant to oxidative stress and UV light. Age-1 mutants also have a higher DNA repair capability than wild-type C. elegans. Knockdown of the nucleotide excision repair gene Xpa-1 increases sensitivity to UV and reduces the life span of the long-lived mutants. These findings support the hypothesis that DNA repair capability underlies longevity. (en)
