Complex interactions between aging and the endocrine system include an important role of hormones in mediating effects of genotype on longevity. In Caenorhabditis elegans and Drosophila melanogaster, striking extension of life span can be produced by targeted disruption (knock out, KO) of genes that control signaling pathways homologous to insulin/insulin-like growth factor signaling in mammals. In the mouse, Mus musculus, longevity is greatly increased by spontaneous and expe...
