The gene was aptly named after the Greek Goddess who spins the threads of life. In 2005, the same investigator did the opposite experiment and showed that transgenic overexpression of <i>klotho<\/i> in mice extends life, placing Klotho once again in the spotlight and generated volumes of antiaging research [<a href=\"https:\/\/www.karger.com\/Article\/Fulltext\/499864#ref2\">2<\/a>]. Several findings that followed changed the landscape. Klotho is a single-pass transmembrane protein, primarily expressed in the kidney, but its extracellular domain is secreted into circulation as a soluble protein after being cleaved by proteases [<a href=\"https:\/\/www.karger.com\/Article\/Fulltext\/499864#ref3\">3<\/a>]; thus, the kidney supplies the body with soluble Klotho [<a href=\"https:\/\/www.karger.com\/Article\/Fulltext\/499864#ref3\">3<\/a>]. In multiple preclinical studies with diverse models, both acute and chronic kidney diseases are states of renal and systemic <i>klotho<\/i> deficiency [<a href=\"https:\/\/www.karger.com\/Article\/Fulltext\/499864#ref3\">3<\/a>], including human CKD. The relationship between Klotho and kidney disease is more than just a biomarker because restoration of Klotho ameliorated renal dysfunction and extrarenal complications in both acute [<a href=\"https:\/\/www.karger.com\/Article\/Fulltext\/499864#ref4\">4<\/a>] and chronic settings bringing Klotho supplementation into the therapeutic realm. However, how should Klotho be given?<\/p>\n<p>In rodents, several methods have been used successfully to raise systemic Klotho levels (Fig. 1). The transgenic insertion of <i>klotho<\/i> into the genome of a mouse was the first attempt [2]. While this has been enormously useful as proof-of-concept in experimental animals, this technique is not applicable to patients currently. Recombinant Klotho protein was used successfully in the laboratory in both acute and chronic [5] settings that prevented AKI, accelerated AKI recovery, presented and retarded AKI-to-CKD transition, and ameliorated extrarenal complications [4]. Recombinant Klotho protein administration is a method where translation to human therapeutics is much more practical and proximal.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The serendipitous disruption of the klotho gene promoter in 1997 by a cardiologist in Japan begot a phenotype of early multiorgan failure mimicking premature aging [1].
