  • Phenotype

    Kv1.3 gene-targeted deletion improves longevity and fecundity. The decreased fecundity typically reported for MC4R-null mice was partially rectified in Kv/MC4R-null animals in comparison to the greater than 80% pregnancy rates of either WT or Kv-null mice. The mean lifespan of the Kv-null mice significantly increased by 22% over that of WT mice whereby lifespan of the MC4R-null mice, oppositely, was significantly reduced by 36% in comparison to that of WT mice. Gene-targeted deletion of Kv1.3 in MC4R-null mice returned the lifespan of these mice to approximately WT levels.

  • Lifespan comparisons

    Double mutant Kv1.3(KO);MC4R(KO) has a lifespan of 669.167 days, while single mutant MC4R(KO) has a lifespan of 547.501 days, single mutant Kv1.3(KO) has a lifespan of 973.3 days and wild type has a lifespan of 851.668 days.
