Here we demonstrate the role of apelin (apln) in mammalian aging and identify it as a novel anti-aging factor. We show that apln and its receptor (aplnr) undergo an age-dependent decline in multiple organs. Declining apln levels perturb organismal homeostasis‚ as mice harboring genetic loss of apln (apln-/-) or aplnr (aplnr-/-) exhibit an age-dependent enhancement of their cardiovascular‚ renal‚ metabolic
