Background: Klotho deficiency is a significant predictor of cardiovascular disease (CVD)-related mortality and morbidity. However, research assessing the association between klotho and individual risk factors of CVD is limited. This study aimed to explore the association between circulating serum klotho levels and risk factors for CVD in adults.
Methods: We used the 2007-2016 National Health and Nutrition Examination Survey and included 13,154 participants for whom serum klotho levels were available. Body mass index (BMI), exercise, smoking status, alcohol consumption, hypertension, dyslipidemia, serum lipid parameters, and blood pressure were considered as CVD risk factors.
Results: Circulating klotho levels were negatively associated with being overweight (beta coefficient: - 22.609, p = 0.0025), obesity (beta coefficient: - 23.716, p = 0.0011), current smoking (beta coefficient: - 46.412, p < 0.0001), and alcohol consumption (beta coefficient: - 51.194, p < 0.0001). There was a positive association between serum klotho levels and no history of dyslipidemia (beta coefficient: 15.474, p = 0.0053). Serum klotho levels were significantly decreased by a unit increase in triglycerides (beta coefficient: - 0.117, p = 0.0006) and total cholesterol (beta coefficient: - 0.249, p = 0.0002). There was a significant non-linear relationship between serum klotho levels, triglycerides, and total cholesterol.
Conclusions: Lower serum klotho levels are associated with certain CVD risk factors, including high BMI, smoking, alcohol consumption, and lipid parameters (triglycerides and total cholesterol). This study suggests that the soluble klotho level may be a potential marker for CVD risk.

Beyond the common comorbidities related to obesity, such as type 2 diabetes and cardiovascular diseases, impaired lung function is already known, but whether the fat distribution (sub-cutaneous, visceral) affects the lung function and pulmonary immune response are poorly known. Few evidence has shown that visceral fat is associated with insulin resistance, low-grade inflammation, and reduced lung function. In the present study, the body composition and fat distribution were evaluated by multi-frequency octopolar bioimpedance.

This study examines α-klotho levels in depressed American adults and their association with cardiovascular disease and all-cause mortality, utilizing data from the National Health and Nutrition Examination Survey (2007-2016) and mortality details from the National Death Index up to December 31, 2019. Including 3329 participants with depression, findings revealed 485 all-cause and 113 cardiovascular deaths. To investigate the nonlinear association between α-klotho and mortality, the Cox proportional hazards regression model, restricted cubic splines, and two-piecewise Cox proportional hazards model were developed.

Klotho deficiency is prevalent in various chronic kidney diseases. Although klotho is known to bind transforming growth factor β (TGFβ) receptor 1 to antagonize renal fibrosis, TGFβ also maintains regulatory T cells with inducing forkhead box protein P3 (FOXP3). Female New Zealand Black/White F (NZBWF1) mice were divided into two groups (n=10 for each): one group was treated with daily subcutaneous injection of klotho protein (30 μg/kg/day) for 8 weeks, and the other only received vehicle.

Background: This is the initial investigation assessing the association between caffeine consumption through diet and circulating Klotho concentrations, with Klotho being recognized as a key biomarker of healthspan and aging.
Methods: This cross-sectional analysis utilized data from 11,169 adults who participated in the National Health and Nutrition Examination Survey (NHANES). Caffeine consumption was evaluated using 24-h dietary recall interviews by trained professionals, and serum Klotho concentrations were measured via an enzyme-linked immunosorbent assay (ELISA).

Background: The renal renin-angiotensin system (RAS) plays a vital part in the control of blood pressure and is known to be affected by aging. This study aimed to investigate the effects of intermittent fasting on age-related hypertension and the expression of local renal RAS components.
Methods: The Wistar rats were categorized into three main age groups (young, middle aged, and elderly) and three dietary treatment models, including ad libitum feeding (AL), every other day fasting (EOD), and one day per week of fasting (FW).
