Objective: The controversial results on the physiopathological role of visfatin led us to examine both circulating visfatin levels and gene expression in visceral (VAT) and subcutaneous fat (SAT) in a homogeneous group of morbidly obese women.
Design, Patients And Measurements: We analysed circulating levels of several adipo/cytokines in 133 Spanish women: 40 lean (C) [body mass index (BMI) < 25 kg/m(2) ] and 93 morbidly obese (MO) (BMI > 40 kg/m(2) ). In the MO group, we found 31 diabetic and 62 nondiabetic subjects.
Objective: The adipocyte/macrophage fatty acid-binding protein 4 (FABP4) has been described as a biomarker for adiposity and metabolic syndrome (MS). The aims of this study were to assess the relationship between FABP4 and inflammatory cytokines related to obesity, and to evaluate FABP4 mRNA expression in visceral and subcutaneous adipose tissue in non-diabetic morbidly obese women versus healthy lean women.
Methods: We analyzed circulating levels of FABP4 in 81 Spanish women: 38 lean (body mass index (BMI)<25 kg/m(2)) and 43 morbidly obese (BMI>40 kg/m(2)).
Background: The fat mass and obesity associated (FTO) gene has been found to contribute to the risk of obesity in humans, but the function and regulation of FTO mRNA expression in adipose tissues remain to be clarified. Our aims were to assess the FTO gene expression in subcutaneous and visceral adipose tissues from morbidly obese women and its relation with obesity, insulin resistance indices, and most importantly, to obesity-related inflammatory markers.
Methods: Paired subcutaneous and visceral fat were excised from 33 morbidly obese women and 12 control women who underwent bariatric surgery by laparoscopic gastric by-pass and elective surgery respectively.
