Summary Genetic deletion in mice of pregnancy‐associated plasma protein A (PAPP‐A), a recently identified metalloproteinase in the insulin‐like growth factor system, extends by 30–40% both mean and maximum lifespan with no reduction in food intake or secondary endocrine abnormalities. Furthermore, these mice have markedly reduced incidence of spontaneous tumors. The findings implicate PAPP‐A as a critical regulator of lifespan and age‐related diseases, and suggest PAPP‐A as a possible target to promote longevity.
