High blood levels of protein may help preserve kidney functi
Higher blood levels of a protein called klotho may help preserve kidney function, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). Although additional studies are needed, the findings point to a potential target for preventing and treating kidney disease.

Soluble klotho is a protein circulating in the blood that is thought to have anti-aging properties. Although the exact mechanism of action of soluble klotho remains to be identified, the protein has been shown to influence multiple cellular and endocrine pathways. The kidney has the highest levels of klotho expression and is likely the major source of soluble klotho. Not surprisingly, therefore, levels of klotho tend to be low in patients with kidney disease...
