Details

Disruption of the protein kinase A regulatory subunit RIIbeta increased life span in male, but not female, mice

Mutations that cause a reduction in protein kinase A (PKA) activity have been shown to extend lifespan in yeast. Loss of function of mammalian RIIbeta, a regulatory subunit of PKA expressed in brain and adipose tissue, results in mice that are lean and insulin sensitive.
