NameTRp63
OrganismMus musculus
Aging PhenotypeShortened life-span
Allele TypeDeletion
StrainUnknown
DescriptionHeterozygous p63+/- mice have a lifespan 21.5% shorter than +/+ control animals (Keyes et al., 2005).
Gene FunctionTrascriptional activator and repressor.
Other PhenotypesThe decreased longevity of p63+/- mice was almost identical to that observed for p53+/m mice, a mouse model in which enhanced p53 activity provided resistance to spontaneous tumors while simultaneously accelerating the aging process (Tyner et al. 2002).
p63+/- mice were not susceptible to spontaneous tumors (Keyes et al., 2005).
