Individualized analysis of subcutaneous and omental abdominal adipose tissue from non-obese and obese subjects

ABSTRACT: Individualized analysis through expression profiling of 20,000 probes in 28 tissue samples evaluated in subcutaneous and omental adipose tissue obtained during surgical intervention in non-obese and obese patients. Patients consisted of men and women of varying body size (lean to severely obese). Samples were collected at the time of operation in the fasting state. Samples consisted of subcutaneous and omental adipose tissue as well as a blood sample from lean and obese men and women removed in the fasting state at the time of surgery.

<h4>Background</h4>Prevalence of obesity is increasing to pandemic proportions. However, obese subjects differ in insulin resistance, adipokine production and co-morbidities. Based on fasting plasma analysis, obese subjects were grouped as Low Acylation Stimulating protein (ASP) and Triglyceride (TG) (LAT) vs High ASP and TG (HAT). Subcutaneous (SC) and omental (OM) adipose tissues (n = 21) were analysed by microarray, and biologic pathways in lipid metabolism and inflammation were specifically ...[more]

Transcription profiling of cultured human preadipocytes/stromal vascular cells from obese and non-obese Pima Indians

Project description:Microarray analysis comparing gene expression profiles of primary cultured preadipocytes from non-diabetic lean vs non-diabetic obese Pima Indian subjects (a subset of the subjects from the adipocyte genechip project, GSE2508). Primary cultured abdominal subcutaneous preadipocytes from 14 lean (7 Males / 7 Females) and 14 obese (7M/7F) subjects were hybridized individually to Affymetrix oligonucleotide arrays HG-U133A and B.

Microarray of isolated adipocytes from subcutaneous adipose tissue of severely obese patients compared to lean controls

Project description:The aim of the project was to compare global gene expression in adipocytes from obese patients and lean controls. Subcutaneous adipose tissue was collected from severely obese patients undergoing bariatric surgery (average body-mass index (BMI) of 45.5 kg/m2 (n = 12, thereof 4 men) and healthy lean patients undergoing hernia repairs (average BMI of 24.2 kg/m2 (n = 12, thereof 7 men), between 27 and 56 years of age. Adipocytes were isolated by collagenase treatment of adipose tissue, followed by filtering and centrifugation. Floating adipocytes were lysed in Qiazol before RNA purification and microarray analysis.

Transcriptome profile of subcutaneous adipocytes isolated from obese vs. lean postmenopausal women

Project description:Adipocytes isolated from lean and obese postmenopausal women with no significant differences in metabolic syndrome parameters demonstrate changes in multiple inflammatory, metabolic and structural gene families. Purified adipocyte samples were isolated from subcutaneous adipose tissue surgical biopsies of 7 obese (BMI>30) and 7 lean (BMI<25) postmenoposal women and gene expression was quantified with Agilent-014850, 4X44K human whole genome platform arrays (GPL6480)

Subcutaneous and gonadal adipose tissue transcriptome differences in lean and obese female dogs

Project description:Adipose, once considered an inert storage depot, is now known to be an active endocrine tissue involved in total body homeostasis and metabolism, which exerts effects on multiple systems including food intake, immune function, and blood glucose regulation. Adipose tissue depots are known to have unique metabolic and gene expression profiles in vivo and when cultured in vitro. Differences in adipose tissue depot function could be important in determining chronic disease risk. Few comparisons of depot gene expression have been performed in the dog. Utilizing microarray technology, our objective was to identify differentially expressed genes and enriched functional pathways between subcutaneous and gonadal adipose of lean and obese dogs. Subcutaneous and gonadal adipose tissue samples were collected from 9 intact female beagles (4 yr-old; 4 lean controls; 5 obese ad libitum-fed) after 24 wk of ad libitum feeding.

Adipocyte-derived Exosomal miRNAs from Subcutaneous Adipose Tissue: A Novel Mechanism for Obesity-Related Disease

Project description:Affymetrix miRNA 3.0 array profiling of adipocyte-derived exosomes from obese and lean human subjects. We used miRNA arrays to profile exosomes shed from obese and lean human subcutaneous fat that was cultured for 60 minutes. Human obese and lean subcutaneous fat were surgically acquired, dissected, and promptly cultured for 60 minutes. We used the culture supernatants for exosome purification and isolation using ExoQuick-TC Precipitation Solution.

Expression data from Adipose Stem Cells (ASC) from morbidly obese and non-obese individuals

Project description:The adipose tissue is an endocrine regulator and a risk factor for atherosclerosis and cardiovascular disease when by excessive accumulation induces obesity. Although the adipose tissue is also a reservoir for stem cells (ASC) their function and “stemcellness” has been questioned. Our aim was to investigate the mechanisms by which obesity affects subcutaneous white adipose tissue (WAT) stem cells. We used microarrays to analyze differences in transcriptomic profiles between the adipose stem cells from morbidly obese and non-obese individuals. Subcutaneous white adipose tissues that were obtained during bariatric surgery (Obese) or liposuction (Lean) were donated by patients after obtaining informed consent. Three cases with BMI>40 kg/m2 (ASCmo) and three controls with BMI<25 kg/m2 (ASCn) were selected and processed extracting total RNA, processing and hybridizating on microarrays.

miRNA expression profile in subcutaneous adipose tissue from morbid obese patients

Project description:To evaluate wether miRNA expression patterns contributes to obesity total RNA were purified from subcutaneous adipose tissue (SAT)and used in miRNA microarrays. Platform contain LNA-modified probes for all human miRNAs present in release 8.2 of the miRBase microRNA Registry. Two RNA pools from 3 non obese men (CM) and from 5 non obese women (CW) were used as controls. Expression profiling revealed that a large set of miRNAs is expressed in SAT. Forty two miRNAs changed by at least 1.5 folds in 17/20 obese subjects versus non obese control pool. Particularly, 21/42 were up-regulated and 21/42 were down-regulated. Among the differentially expressed miRNA, miR-519d, miR-498 and miR-150 were up-regulated, miR-659 and miR-371-3p_MM2 were down-regulated consistently in 20/20 obese subjects. To search for miRNAs eventually associated with obesity we used a microarray to evaluate the expression of 1458 different miRNAs in 10 obese women (OBW) and 10 obese men (OBM). Two RNA pools from 3 non obese men (CM) and from 5 non obese women (CW) were used as controls.
