Project description:Distinct characteristics of adipose tissue at different localization of human body has shown greater significance in development of metabolic disorders. Visceral adipose tissue in particular is known to be associated with obesity related metabolic complications that include type II diabetes. In this experiment, we attempt to profile transcriptome signatures of adipocyte, stromal vascular fraction (SVF) and adipose tissue from subcutaneous and visceral adipose tissue from obese individuals.

Project description:Subcutaneous adipose tissue and visceral adipose tissue samples were obtained from severely obese individuals that underwent bariatric surgery. The goal of this study was to compare genome-wide gene expression levels in the two tissue types from healthy and unhealthy severely obese individuals. Whole-transcriptome subcutaneous adipose tissue gene expression levels were determined in 73 individuals with a BMI >35 kg/m2. Whole-transcriptome visceral adipose tissue gene expression levels were determined in 69 individuals with a BMI >35 kg/m2. Modules of co-expressed genes likely to be functionally related were identfied and correlated with BMI, plasma levels of glucose, insulin, HbA1c, triglycerides, non-esterified fatty acids, ALAT, ASAT, C-reactive protein, and LDL- and HDL cholesterol.

Project description:To investigate the proteomic profiles of paired subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) samples, as well as their correlations with clinical traits in severely obese patients, and to identify potential serum protein markers associated with tissue expression or metabolic states.

Project description:Visceral adipose tissue samples were obtained from severely obese individuals that underwent bariatric surgery. The goal of this study was to identify tissue specific methylation QTLs. Whole-transcriptome subcutaneous adipose tissue methylation levels were determined in 71 individuals with a BMI >35 kg/m2. Bisulphite converted DNA from the 71 visceral adipose tissue samples were hybridised to the Illumina Infinium 450k Human Methylation Beadchip.

Project description:As a serious public health problem nowadays, obesity and its complications are receiving gradually more attention, especially on how food-induced obesity causes the expansion of adipose tissue and leads to the occurrence of metabolic inflammation and infiltration of immune cells. It's still worth mentioning that numerous genes in adipose tissue which differ between obese and normal individuals in food-induced obesity were not insufficiently studied. Applying machine learning methods and natural language processing methods on transcriptome datasets and PubMed abstracts, we investigated 8 genes with differential expression and high association with macrophages in the visceral and subcutaneous adipose tissue between obese and normal individuals, and meanwhile low correlation with leptin. Compared with normal group, Quantitative Real-time Polymerase Chain Reaction, Western Blot, immunohistochemistry, immunofluorescence and other subsequent animal experiments on the 8 filtered genes were applied in the adipose tissue of C57BL/6J and OB/OB mice, we found that the expression of glycoprotein IX (GP9), MHC class I polypeptide related sequence B (MICB), CDGSH iron sulfur domain 1 (CISD1) and Pre-mRNA-processing factor 19 (PRPF19) in protein level were down-regulated in visceral fat of obese mice induced by high-fat diet. And these obese mice showed decreased levels of mannosidase alpha class 2B member 1 (MAN2B1) and TYRO protein tyrosine kinase binding protein (TYROBP) in their subcutaneous adipose tissue, while phosphate and tension homology deleted on chromosome pten (PTEN) and eukaryotic translation initiation factor 4E binding protein 1 (EIF4EBP1) had been sufficiently studied. The pattern in OB/OB mouse was dramatically different with these patterns. Through double immunofluorescence staining, it was found that all genes were co-localized with CD206, which was the marker of M1 and M2 macrophage in adipose tissue. Further interacting drugs for the genes were calculated and subsequently circumin and beta-catonin were proved to be interacting with these genes and functioned in inhibiting food-induced obesity. Further knowledge gragh was constructed to illustrate the relationship between obesity, filtered genes, drugs and related concepts. To summarize our findings, we discovered some new differential genes in adipose tissue which could potentially establish a new connection between adipose tissue macrophages and food-induced obesity. Furthermore, they offered unique insights into exploring the mechanism of adipose tissue genes related to food-induced obesity and related diseases.

Project description:Using RNA isolated from subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) samples obtained from control and class I, II and III obese patients undergoing inguinal hernia repair and laparoscopic cholecystectomy, we compared the gene expression profiles between SAT and VAT using microarrays and validated the findings by real-time quantitative PCR.

Project description:The association between central obesity and insulin resistance reflects the properties of visceral adipose tissue. Our aim was to gain further insight into this association by analysing the lipid composition of subcutaneous and omental adipose tissue in obese women with and without insulin resistance. Subcutaneous and omental adipose tissue and serum were obtained from 29 obese nondiabetic women, 13 of whom were hyperinsulinemic. Histology, and lipid and gene profiling were performed. In omental adipose tissue of obese, insulin-resistant women, adipocyte hypertrophy and macrophage infiltration were accompanied by an increase in GM3 ganglioside and its synthesis enzyme ST3GAL5; in addition, phosphatidylethanolamine (PE) lipids were increased and their degradation enzyme, PEMT, decreased. ST3GAL5 was expressed predominantly in adipose stromovascular cells and PEMT in adipocytes. Insulin resistance was also associated with an increase in PE lipids in serum. Total RNA was isolated and up to 400 ng of total RNA per sample was labelled and hybridized to Illumina HumanHT-12_V4 expression BeadChip platform. Paired subcutaneous and omental samples from 6 women were analysed.
