Project description:Genes showing differential expression in visceral adipose tissue obtained from Asia Indian obese women suffering from type-2 diabetes mellitus as compared to age and BMI matched normal glucose tolerant women were identified by genome wide transcriptomic profiling in 5 diabetic and 5 control subjects respectively.
Project description:Case story. A patient with massive infiltration of the visceral adipose tissue depot by BAT in a patient with a catecholamine secreting paraganglioma. BAT tissue was identified by protein expression of UCP1 (western blotting and immunostaining) The goal of the study is to identify patterns of gene expression in BAT containing visceral fat compared to the patient's own subcutanous fat which did not express BAT. For comparison a pool of mRNA isolated from visceral fat from obese subjects was used. Patient Case, Gene expression array from a biopsy from the patient's visceral fat and a biopsy from the subcutaneous fat compared to one array of mRNA from the visceral depot pooled from a group of obese subjects
Project description:Context: It is not known whether biological differences reported between subcutaneous (SAT) and visceral (VAT) adipose tissue depots underlie the pathogenicity of visceral fat. Objective: We compared SAT and VAT gene expression according to obesity, visceral fat accumulation, insulin resistance and presence of the metabolic syndrome. Design: Subjects were assigned into 4 groups (lean, overweight, obese and obese with metabolic syndrome). Setting: Subjects were recruited at a university hospital. Patients: 32 women were included. Main Outcome Measures: Anthropometric measurements, euglycemic hyperinsulinemic clamps, blood analyses and computed tomography scans were performed and paired samples of SAT and VAT were obtained for DNA microarray-based gene expression profiling.
Project description:In addition to total body fat, the regional distribution and inflammatory status of enlarged adipose tissue are strongly linked to metabolic and cardiovascular complications of obesity. We recently showed that the severity of liver non-alcoholic histopathology in obese subjects increased with the amounts of macrophages in visceral adipose tissue (VAT), while no relation was found with the subcutaneous adipose tissue (SAT). In the abdominal region, SAT is anatomically divided into superficial (sSAT) and deep (dSAT) layers. The aim of the present study was to test the hypothesis that these distinct compartments differentially contribute to hepatic alteration in obesity. Total RNA was isolated from two different strata of human adipose tissue of 8 subjects.
Project description:Identification of the inflammatory signature in visceral adipose tissue CD14+ cells (adipose tissue macrophage) Total RNA obtained from CD14+ cells (Immunoselcted cells from stromal adipose tissue cells) Adipocytes and cells of the stroma vascular fraction (SVF) were obtained by collagenase digestion of adipose tissue. SVF cells were resuspended in endotoxin-free PBS supplemented with 2% FCS and 1 mM EDTA. Isolation of CD14+ using positive selection magnetic beads (Stemcell technologies) and CD4+ cells was performed using positive selection magnetic beads (Stemcell Technologies, Vancouver, Canada). An Illumina (San Diego, CA) RNA amplification kit (NuGEN, BiotinIL Module) was used according to the manufacturer's instructions to obtain biotinlabeled cDNA from 50 ng of total RNA extracted from adipose tissue CD14+ cells.

Project description:In order to explore the effect of hypertension and overweight/obesity on human visceral adipose tissue transcriptome, we collected three visceral adipose tissue samples from normal weight individuals (non hypertension), overweight/obese individuals (non hypertension) and overweight/obese individuals with hypertension, and sequenced their transcriptome.
