Abstract

Objective: The role of glucocorticoids production in adipose tissue in the development of metabolic disorders in humans has not been fully characterized. We investigated whether in obese subjects, 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) expression in subcutaneous (SAT) and visceral (VAT) adipose tissue is associated with the occurrence of metabolic disorders and the expression of adiponectin and tumor necrosis factor α (TNFα) and two glucocorticoid-regulated adipokines able to influence the metabolic control. Design and subjects: Sixty-two obese patients were enrolled in the study. SAT and VAT samples were obtained from 13 patients undergoing bariatric surgery (body mass index (BMI) 39.1±5.3 kg/m2). SAT samples were obtained from 49 patients who underwent periumbilical biopsy (BMI 36.9±5.1 kg/m2). Measurements: Oral glucose tolerance tests in subjects without known diabetes. Circulating glucose, lipid, insulin, adiponectin, TNFα and urinary-free cortisol levels. Real-time PCR to quantify mRNA levels of 11β-HSD1, hexose-6-phosphate dehydrogenase (H6PDH), adiponectin and TNFα. Western blot analysis to evaluate 11β-HSD1 protein expression. Results: In the majority of the obese subjects, VAT expresses more 11β-HSD1 than SAT. VAT 11β-HSD1 expression was not associated with metabolic disorders. SAT 11β-HSD1 mRNA levels were higher in subjects with than in those without metabolic syndrome (P
