Pattern of Gene Expression in Adipose Tissue From Patients With Cushing Syndrome

"The purpose of this trial is to investigate the impact of cortisol on adipose tissue functions, distribution and morphology. Patient with endogenous blood cortisol excess exhibit changes in adipose tissue, with fat gain in the upper trunk, face and neck leading to visceral obesity and features of the metabolic syndrome. The aims of this study will be~* to compare the pattern of gene expression between visceral and subcutaneous adipose tissue in Cushing patients requiring an adrenalectomy as cortisol adenoma treatment;~* to compare these patterns of gene expression with those of two control populations:1/ healthy metabolic subjects having a partial nephrectomy, 2/obese patients with similar degree of insulin resistance."
