Abstract

Klotho was initially identified as an anti-ageing protein expressed mainly in renal distal tubular cells and the choroid plexus. The Klotho family comprises several members, including α-Klotho (αKl), β-Klotho (βKl), Klotho-LPH related protein (KLPH; lactase-phlorizin hydrolase), and Klotho-related protein (KlrP), which perform a multitude of functions related to various physiological processes. The effects of Klotho on various ageing-related and renal diseases, such as its antiapoptotic effects, ability to reduce oxidative stress, anti-inflammatory effects, and other functions, have extensively been reviewed, suggesting the significant cardiorenal benefits of Klotho. Klotho expression deficiency promotes age-related pathology and is correlated with renal impairment. Studies have shown that serum Klotho is significantly decreased in type 2 diabetes (T2DM) and is linked to the duration of diabetes, indicating that Klotho may be involved in multiple pathological mechanisms of T2DM. Insulin resistance (IR) plays an essential role in the onset and progression of T2DM. Research has demonstrated that the expression of Kl is closely correlated with insulin secretion, insulin signaling pathways, and insulin sensitivity and may serve as a potential predictive marker for the IR and diabetes risk. We comprehensively reviewed the relevant literature in PubMed using the keywords "Klotho", "Type 2 diabetes", and "Insulin resistance". This review summarizes the relationship between Klotho and IR.

Research summary

Klotho protein is correlated with insulin resistance and may serve as a predictive marker for diabetes risk. The paper is relevant as it explores the role of Klotho in aging-related mechanisms, particularly its potential influence on insulin resistance and type 2 diabetes, which are significant factors in age-related health decline.
