Project description:Previous publications demonstrated that there were anatomical, physiological, cellular, clinical and prognostic differences among adipose tissue present in subcutaneous areas, abdominal cavity and outside adventitial layer of artery. Thus, we wondered whether ASCs from subcutaneous adipose tissue, abdominal adipose tissue and perivascular adipose tissue were also different in gene expression. Here we performed bulk RNA-Seq assay for subcutaneous, abdominal and perivascular adipose derived stem cells.

Project description:To identify genes differentially expressed in abdominal and gluteal adipose tissue, we determined the mRNA transcription profile of 10 abdominal and 10 gluteal female adipose tissue sections using Agilent Whole Human Genome Microarrays. RNA of 10 subcutaneous abdominal and 10 subcutaneous gluteal fat depot samples was processed by Miltenyi Biotech GmbH (Bergisch Gladbach, Germany) and loaded on single-color Whole Human Genome 4x44K microarrays (G4112F) from Agilent Technologies.

Project description:In humans, adipose tissue is distributed in subcutaneous abdominal and subcutaneous gluteal depots that comprise a variety of functional differences. Whereas energy storage in gluteal adipose tissue has been shown to mediate a protective effect, an increase of abdominal adipose tissue is associated with metabolic disorders. However, the molecular basis of depot-specific characteristics is not completely understood yet. Using array-based analyses of transcription profiles, we identified a specific set of genes that was differentially expressed between subcutaneous abdominal and gluteal adipose tissue. To investigate the role of epigenetic regulation in depot-specific gene expression, we additionally analyzed genome-wide DNA methylation patterns in abdominal and gluteal depots. By combining both data sets, we identified a highly significant set of depot-specifically expressed genes that appear to be epigenetically regulated. Interestingly, the majority of these genes form part of the homeobox gene family. Moreover, genes involved in fatty acid metabolism were also differentially expressed. Therefore we suppose that changes in gene expression profiles might account for depot-specific differences in lipid composition. Indeed, triglycerides and fatty acids of abdominal adipose tissue were more saturated compared to triglycerides and fatty acids in gluteal adipose tissue. Taken together, our results uncover clear differences between abdominal and gluteal adipose tissue on the gene expression and DNA methylation level as well as in fatty acid composition. Therefore, a detailed molecular characterization of adipose tissue depots will be essential to develop new treatment strategies for metabolic syndrome associated complications. DNA methylation profiles of abdominal adipose tissue (6 samples) and gluteal adipose tissue (6 samples) were generated using Infinium methylation 450K BeadChips from Illumina (Illumina, San Diego, USA).

Project description:Inflammatory crosstalk between perivascular adipose tissue and and blood vessel wall may contribute to atherosclerosis pathogenesis, and exhibits more pro-inflammatory than adipogenic phenotype than subcutaneous adipocytes. To identify a genomic basis for biologic differences, we performed genome-wide expression to identiy expression genes differentially regulated between perivascular and subcutaneous adipocytes.for biologic differences. We performed global gene expression analyses on in vitro differentiated adipocytes from human left coronary artery perivascular adipose tissue and subcutaneous adipose tissues derived from unrelated donors who were non-obese and did not have any known metabolic or atherosclerotic disease.

Project description:Background and objective: Combination antiretroviral therapy (cART) is associated with lipodystrophy i.e. loss of subcutaneous adipose tissue in abdomen, limbs and face and its accumulation intra-abdominally. No fat is lost dorsocervically and it can even accumulates in this region (“buffalo hump”). It is unknown how preserved dorsocervical fat differs from abdominal subcutaneous fat in HIV-1-infected cART-treated patients with (cART+LD+) and without (cART+LD-) lipodystrophy. Results: Albeit dorsocervical adipose tissue in cART+LD+ seems spared from lipoatrophy, its mitochondrial DNA (mtDNA, copies/cell) content was significantly lower (by 62%) than that of the corresponding tissue in cART+LD-. Expression of CD68 mRNA, a marker of macrophages, and numerous inflammatory genes in microarray were significantly lower in dorsocervical vs. abdominal subcutaneous adipose tissue. Genes with the greatest difference in expression between the two depots were those involved in regulation of transcription and regionalization (homeobox genes), irrespective of lipodystrophy status. There was negligible mRNA expression of uncoupling protein 1, a gene characteristic of brown adipose tissue, in either depot. Conclusions: As mtDNA is depleted even in the non-atrophic dorsocervical adipose tissue, it is unlikely that the cause of lipoatrophy is loss of mtDNA. Dorsocervical adipose tissue is less inflamed than lipoatrophic adipose tissue. It does not resemble brown adipose tissue. The greatest difference in gene expression between dorsocervical and abdominal s.c. adipose tissue is in expression of homeobox genes. We used histology, microarray, polymerase chain reaction and magnetic resonance imaging to compare dorsocervical and abdominal subcutaneous adipose tissue in cART+LD+ (n=21) and cART+LD- (n=11). The study consists of 17 patients on antiretroviral treatment who have developed lipodystrophy and 11 patients that are on similar treatment but have not developped lipodystrophy. All patients are HIV+ and have 2 adipose tissue samples taken from them (dorsocervical+abdominal).

Project description:Perivascular adipose tissue (PVAT) is thought to play a role in vascular homeostasis and in the pathogenesis of diseases of large vessels, including abdominal aortic aneurysm (AAA). We tested the hypothesis that locally restricted transcriptional profiles characterize PVAT surrounding AAA. Using a genome-wide approach, we investigated the PVAT transcriptome of AAA in 30 patients with either large (≥55 mm) or small (<55 mm) aneurysm diameter. We performed a data adjustment step using the DaMiRseq R/Bioconductor package, to remove the effect of confounders as produced by high-throughput gene expression techniques. We compared PVAT of AAA with PVAT of not-dilated abdominal aorta of each patient to limit the effect of inter-individual variability, using the limma R/Bioconductor package. We found highly consistent differences in PVAT gene expression clearly distinguishing PVAT of AAA from PVAT of not-dilated aorta, which increased in number and magnitude with increasing AAA diameter. These changes did not systemically affect other abdominal adipose depots (omental or subcutaneous fat). We dissected putative mechanisms associated with PVAT involvement in AAA through a functional enrichment network analysis: both innate and adaptive immune-response genes along with genes related to cell-death pathways, metabolic processes of collagen, sphingolipids, aminoglycans and extracellular matrix degradation were strongly overrepresented in PVAT of AAA compared with PVAT of not-dilated aorta. Our results provide support to a possible role of PVAT in AAA pathogenesis and suggest that AAA is an immunologic disease with an underlying autoimmune component. These disease-specific expression signatures could help identifying pharmacological targets for preventing AAA progression.

Project description:FCHL is a common, complex genetic lipid disorder with a largely unknown aetiology. Altered adipose tissue metabolism has been implicated as contributing to FCHL. We used microarrays to investigate the mRNA profiles of FCHL patients with CHD and non-FCHL patients with CHD in comparison with non-FCHL, non-CHD patients to define a core set of genes that were differentially expressed in FCHL and to provide a reasonable launch-pad for examining the direct contribution of one of this gene set to the development of adipose tissue. Adipose tissue was obtained from the same anatomical site - the subcutaneous, upper abdominal region - of white British males, either at coronary artery bypass surgery (designated as: FCHL-CHD (13 individuals, subdivided on TG response to statins into Group 1 (n=4), Group 2 (n=7) and unclassified (n=2)) and non-FCHL-CHD patients (6 individuals)), or at heart valve replacement: non-FCHL, non-CHD subjects (5 individuals; controls).
