background: leptin plays a key role in the regulation of energy expenditure and is known to circulate in both free and bound forms. soluble leptin receptor (sob-r) is a unique circulating form of leptin receptor that can bind to leptin. leptin and leptin receptor have been implicated in processes leading to breast cancer initiation and progression. our study was aimed to investigate the relatio...

background: leptin is an adipokine that circulates in a free form and bound to a soluble leptin receptor. patients with polycystic ovary syndrome have increased insulin resistance and high incidence of obesity. objective: this study was carried out to evaluate levels of leptin and free leptin in women with polycystic ovarian syndrome (pcos) and note any relationships with insulin resistance and...

The aim of the study was to investigate whether diverse clinical blood pressure phenotypes are associated with free leptin surrogates, as reflected by plasma leptin, human soluble leptin receptor, and their ratio (ie, free leptin index) in nonobese normoglycemic subjects. Three separate clinic blood pressure measurements and ambulatory blood pressure monitoring were implemented to divide 494 su...

introduction: leptin is a hormone resulting from the obesity gene which could be important in the pathogenesis of the insulin. only limited data concerning the interaction of insulin, glucose tolerance and free leptin are available and no data exist on the potential influence of free vs. bound circulating leptin. we, therefore, studied percentage of free to total leptin in diabetic patients. ma...

Background and Aim. Leptin has two forms in the circulation: free and bound forms. The soluble leptin receptor (sOB-R) circulates in the blood and can bind to leptin. The aim of this study is to assess the concentrations of the leptin and the sOB-R in PCOS and its relation to adiposity, insulin resistance, and androgens. Methods. A cross-sectional study included 78 female students aged 17-25 ye...

A common -2548G/A promoter variant of the human leptin gene has recently been shown to be associated with variations in circulating leptin levels but available data are still conflicting. The aim of this study was to explore potential associations between the -2548G/A polymorphism and adiposity-related variables, plasma total leptin levels, as well as soluble leptin receptor (sOB-R) levels and ...
