Abstract

Since its first identification in 1995, klotho (KL) has become the most promising gene to consider for suppressing aging and aging-related diseases. KL knockout mice exhibited similar phenotypes found in human with premature aging such as short lifespan, osteoporosis, arteriosclerosis and hearing loss. Genetically modified mice overexpressing KL prolonged lifespan more than 20%. Also, clinical reports have indicated decreased concentration of the circulating KL protein in blood, which is called soluble klotho (sKL), is closely related to development of senile diseases. The best way to discover significance of sKL on the development of the diseases might be comparison of sKL concentration between controls and patients. Here we analyzed published clinical reports identified sKL concentration in the cohorts. The sKL concentrations were displayed using heatmap for better comparison. In most of the senile diseases, disease progression was inversely related with sKL concentration. Hypertension was the only disease had no relationship, while schizophrenia was the only disease had direct proportion to the disease progression. Overall, sKL concentration in blood could be a marker to determine current severity of the senile diseases and even to estimate disease progression for the patients at the onset of their senile diseases.
