Benigni et al. [1] showed that mice lacking the Agtr1a gene encoding AT1A, the major mouse AT1 isoform and the closest murine homologue to the single human AT1, exhibit marked prolongation of their lifespan. The longevity in AT1A receptor-deficient mice was not related to caloric intake, but was associated with decreased cardiac, vascular, renal and pancreatic injury, reduced oxidative stress in many organs and increased proximal tubular mitochondrial volume or upregulation of the prosurvival genes nicotinamide phosphoribosyltransferase (Nampt) and sirtuin 3 (Sirt3) in the kidney. In vitro experiments showed that angiotensin II (AngII)
