Low levels of circulating protein linked to kidney function
Decreased blood levels of a protein called soluble klothos were linked with an increased likelihood of experiencing kidney function decline in a group of elderly well-functioning adults.

Higher blood levels of a protein called klotho may help preserve kidney function, according to a study, entitled “Association between Soluble Klotho and Change in Kidney Function: The Health Aging and Body Composition Study,” published in the Journal of the American Society of Nephrology (JASN).
