Klotho in the Pathology of Aging

Klotho is a longevity-associated protein; more of it slows aging, less of it accelerates aging, at least in animal studies. While researchers have spent considerable effort investigating the effects of klotho on the brain, as it improves cognitive function, it seems likely that its effects arise via improved kidney function in old age. Loss of kidney function, and thus clearance of metabolic toxins and waste from the bloodstream, is harmful to tissues throughout the body. Manipulation of klotho may be a good way to assess just how much harm is generated by the age-related decline of the kidneys.

The subject of this review is Klotho (kl), which is an antiaging gene, and the corresponding protein α-Klotho (henceforth denoted Klotho or KL). The gene was first identified in mice in 1997. Deficienc…
