An early inflammatory gene profile in visceral adipose tissue in children

ABSTRACT: The aim of this study was to characterize expression profiles of visceral and subcutaneous adipose tissue in children. Adipose tissue samples were collected from children having elective surgery (n=71, [54 boys], 6.0 +- 4.3 years). Affymetrix microarrays (n=20) were performed to characterize the functional profile and identify genes of interest in adipose tissue. Visceral adipose tissue had an overrepresentation of Gene Ontology themes related to immune and inflammatory responses and subcutaneous adipose tissue had an overrepresentation of themes related to adipocyte growth and development. Likewise, qPCR performed in the whole cohort showed a 30-fold increase in haptoglobin (P < 0.005), 7-fold increase in IL-10 (P < 0.001), 8-fold decrease in VEGF (P < 0.01) and a 28-fold decrease in TBOX15 (P < 0.001) in visceral compared to subcutaneous adipose tissue.The inflammatory pattern in visceral adipose tissue may represent an early stage of the adverse effects of this depot, and combined with chronic obesity, may contribute to increased metabolic and cardiovascular risk.

Dynamic analysis of mononuclear transcription profiles of fat in different parts of mice during aging

Project description:Adipose tissue shows significant changes during aging. Here, we used single-nucleus RNA-seq to map the single-nucleus transcription profiles of mouse subcutaneous adipose tissue ( SAT ) and visceral adipose tissue ( VAT ) at a single-nucleus resolution, showing the differences in visceral and subcutaneous adipose tissue changes with aging. The mononuclear sequencing method enabled us to restore all major cell types in mouse white adipose tissue, and we characterized adipocytes, immune cells, and preadipocytes. We demonstrated the existence of different adipocyte subsets and showed that aging leads to a decrease in adipogenic subsets. In addition, with aging, both subcutaneous adipose tissue and visceral adipose tissue showed a decrease in immune mechanisms.

Expression data from open bariatric surgery patients - various adipose samples

Project description:Diabetes and obesity are widespread diseases with signifciant socioeconomic implications. We used three different types of human adipose tissue (epigastric, visceral, and subcutaneous) in order to determine differences in global gene expression between these adipose depots in severely obese patients. In this dataset, we include the expression data obtained from three types of adipose tissue; epigastric, subcutaneous, and visceral all obtained through open gastric bypass surgery. 18 total samples were analyzed. Tissues were paired together to run on one genechip, with three pairs of epigastric, three pairs of subcutaneous, and three pairs of visceral were ran on nine genechips. Comparisons of gene expression in the form of fold changes between pairs of adipose types (i.e., subcutaneous/epigastric, visceral/epigastric, and subcutaneous/visceral) were completed by Spotfire Analysis.

SARS-CoV-2 infects adipose tissue in a fat depot- and viral lineage-dependent manner

Project description:Visceral adiposity is a risk factor for severe COVID-19, and a link between adipose tissue infection and disease progression has been proposed. Here we demonstrate that SARS-CoV-2 infects human adipose tissue and undergoes productive infection in human primary adipose-derived stromal-vascular cells differentiated into adipocytes. However, the permissiveness to infection and the cellular response depends on the anatomical origin of the cells and the viral lineage. Cells of visceral adipose tissue origin express more ACE2 and are more permissive to SARS-CoV-2 infection than their subcutaneous counterpart. SARS-CoV-2 infection leads to inhibition of lipolysis in cells of subcutaneous origin, while in visceral fat cells, it results in higher expression of pro-inflammatory cytokines. Viral load and cellular response are attenuated when visceral adipose tissue cells are infected with the SARS-CoV-2 gamma variant. A similar degree of cell death occurs 4-days after SARS-CoV-2 infection, regardless of the cell origin or viral lineage. Hence, SARS-CoV-2 infects human adipose tissue cells, replicating and altering cell function and viability in a fat depot- and viral lineage-dependent fashion.
