Irisin (Ir), a recently identified adipomyokine, cleaved and secreted to the circulation from the FNDC5 protein in response to physical activity and some environmental conditions has been postulated to induces the differentiation of a subset of white adipocytes into brown fat and mediates the beneficial effects of exercise on metabolic homeostasis. Polycystic ovary syndrome (PCOS) – one of the most frequent endocrinopathies affecting women of child-bearing age is associat...

Polycystic ovary syndrome (PCOS) is a common endocrine abnormality connected not only with reproductive problems but also with impaired energy homeostasis leading to metabolic disorders including metabolic syndrome. Irisin (Ir), recently identified novel myokine, has been proposed to mediate some of the positive influence on metabolic disorders. The aim of our study was to search the relationship between Ir plasma concentration in PCOS in the context of metabolic disturbances....

Introducing: Acromegaly is characterized by excessive GH and IGF1 secretion. Recent date suggests that soluble α-Klotho is also elevated in patients with acromegaly.Objective: The aim of this study was to assess the serum levels of soluble α-Klotho in patients in relation with the activity of disease and to compare with control group (CG). We also examine the relationship between excess GH, IGF1 and serum levels of soluble α-Klotho in pati...

The aim of this study was to determine whether polymorphisms (TaqI, ApaI, BsmI, and FokI) of the vitamin D receptor (VDR) show a correlation with the serum level of the testosterone in the aging men population.A group of 224 men aged 65–90 years, randomly selected from the group of 5695 persons included in the PolSenior project was studied. We established genotype prevalence of the VDR gene polymorphisms (TaqI, rs10735810; ApaI, rs1544410; BsmI, rs7...

Background: The association between fat mass and obesity-associated gene (FTO) polymorphism rs 9939609 and obesity was found in some European countries. However, the data concerning Polish population is insufficient. The relationship between FTO and metabolic disorders remains unclear.Methods: The study group consisted of 686 women and 418 men from Lower Silesia in Poland, aged 30–80 years (mean age 54.2±9.26 years). The examination included an...

Objective: Genetic factors play a major role in obesity. Numerous studies have confirmed associations of the SNP rs9930506 of FTO gene with increased BMI, hip circumference and total body weight. The metabolic consequences of obesity depend, to a large degree, on body fat distribution.MONW individuals (metabolically obese normal-weight), despite their normal BMI, are characterized by visceral obesity and display metabolic properties that may pre...

Introduction: Acromegaly is a rare diseaseresulting most commonly from pituitary adenoma. A chronic increase of growth hormone (GH) and insulin-like factor 1 (IGF-1) leads to many systemic complications including osteoporosis and fractures. Radiofrequency echographic multi-spectrometry (REMS) is a new non-ionizing technique to diagnose osteoporosis.Purpose: The objective of the study was to evaluate bone mineral density (BMD) by REMS in patient...

Glypican-4 (Gpc-4) is novel adipokine interact with insulin receptor and affects insulin sensitivity in proteoglycans. Gpc-4 serum levels show gender differences; females having higher levels than men, what can suggest mediation by sex hormones. We investigated serum Gpc-4 levels and its association with cardiovascular risk predictors in women (20–35 years old) with PCOS (n=62) and healthy control (n=43) presented different sex hormones profile. The foll...

Skeletal muscle constitutes the largest endocrine organ in human body through capability of secreting myokines, which biological activity plays a key role in energy homeostasis. Among the myokines irisin (Ir) is of particular interest, considering it’s broad spectrum of protective influence on obesity and metabolic diseases development, determining therapeutical potential of this molecule. Latest studies indicate close interrelations between Ir and myostatin (Mstn), myok...

The endocannabinoid system has been suspected to contribute to the association of visceral fat accumulation with metabolic diseases. Insulin resistance play important role in etiology in PCOS. The aim of our study was developed the role of CNR1 polymorphisms (rs806368, rs12720071, rs1049353, 806381, rs10485170, rs6454674, rs2023239) in metabolic disorders in woman with PCOS. 88 woman (20–35 years old) with PCOS (recognized using Rotterdam criteria) and 77 woman (20–3...
