Brown Adipose Tissue (BAT) in Visceral Fat Depot

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

Proteomics on mouse obese and non-obese visceral adipose tissue derived extracellular vesicles

Project description:Visceral adipose tissue (VAT) was harvested from wild-type mice fed high-fat diet to induce obesity or matched diet as non-obese controls. VAT was ex vivo cultured for 48 hrs and its conditioned media was collected. Extracellular vesicles were isolated from conditioned media by ultracentrifugation. The aim of the project was to characterize extracellular vesicle protein cargo from obese and non-obese VAT.

Paracrine Signaling in Visceral Fat

Project description:Accumulation of visceral (VIS) as opposed to subcutaneous (SUB) fat is a predictor of metabolic disorders, insulin resistance, and cardiovascular disease. This is due in part to the limited capacity of VIS fat to buffer lipids allowing them to deposit in insulin-sensitive tissues, thus impairing insulin action. In addition, VIS adipose tissue is more prone to fibrosis and inflammation, which in turn contributes to the pathogenesis of metabolic disease. Mechanisms underlying selective hypertrophic growth and tissue remodeling properties of VIS fat are not well understood. We and others identified subsets of adipose progenitors (APs) unique to VIS fat with differential adipogenic capacity. We named these CD34+ APs VIS low and VIS high based on low or high CD34 expression respectively. Despite sharing the same developmental origin, VIS low APs are adipogenic whereas VIS high APs are not. Furthermore, VIS high APs inhibit adipogenic differentiation of SUB and VIS low APs in vitro through the secretion of soluble inhibitory factor(s) including insulin-like growth factor binding protein 2 (Igfbp2). The number of VIS high APs increased with VIS adipose tissue expansion and their abundance in vivo causes hypertrophic growth, fibrosis, inflammation and impaired glucose and insulin tolerance. This study unveil the presence of APs unique to VIS fat involved in the paracrine regulation of adipogenesis and tissue remodeling.

Proteomics on visceral adipose tissue derived extracellular vesicles from Tsg101 knockout mice

Project description:The protein Tsg101 plays an integral role extracellular vesicle formation and secretion from cells. We developed a mouse model with Tsg101 knockdown (Tsg101dAd). Visceral adipose tissue (VAT) was harvested from Tsg101dAD and Tsg101flfl mice fed high-fat diet to induce obesity or matched diet as non-obese controls. VAT was ex vivo cultured for 48 hrs and its conditioned media was collected. Extracellular vesicles were isolated from conditioned media by ultracentrifugation. The aim of the project was to characterize extracellular vesicle protein cargo from obese and non-obese VAT.

Visceral fat trancriptome in obstructive sleep apnea

Project description:Rationale: Obstructive sleep apnea (OSA) has been associated with metabolic dysregulation and systemic inflammation. This may be due to pathophysiologic effects of OSA on visceral adipose tissue. We sought to assess the transcriptional consequences of OSA on adipocytes by utilizing pathway-focused analyses. Methods: Patients scheduled to undergo ventral hernia repair surgery were recruited to wear a portable home sleep monitor for two nights prior to surgery. Visceral fat biopsies were obtained intra-operatively. RNA was extracted and whole-genome expression profiling was performed. Gene Set Enrichment Analysis (GSEA) was used to identify curated gene sets that were differentially enriched in OSA subjects. Network analysis was applied to a select set of highly enriched pathways. Results: 10 patients with OSA and 8 control subjects were recruited. There were no differences in age, gender, body mass index between the two groups, but the OSA subjects had a significantly higher respiratory disturbance index (19.2 vs. 0.6, P-value 0.05) and worse hypoxemia (minimum oxygen saturation 79.7% vs. 87.8%, P-value < 0.001). GSEA identified a number of gene sets up-regulated in adipose tissue of OSA patients including the pro-inflammatory NF-M-NM-:B pathway and the proteolytic ubiquitin/proteasome module. A critical metabolic pathway, the peroxisome proliferator-activated receptor (PPAR), was down-regulated in subjects with OSA. Network analysis linked members of these modules together and identified regulatory hubs. Conclusions: OSA is associated with alterations in visceral fat gene expression. Pathway-based network analysis highlighted perturbations in several key pathways whose coordinated interactions may contribute to the metabolic dysregulation observed in this complex disorder. Total RNA from visceral fat of 18 subjects (10 OSA, 8 Control) was hybridized to 18 Affymetrix Genechip Human Gene 1.0 ST microarrays.
