Expression data from human SGBS adipocytes under hypoxic conditions

ABSTRACT: Hypoxia in adipose tissue is suggested to be involved in the development of a chronic mild inflammation, which in obesity can further lead to insulin-resistance. The effect of hypoxia on gene expression in adipocytes seems to play a central role in this inflammatory response observed in obesity. However, the global impact of hypoxia on transcriptional changes in human adipocytes is unclear. Therefore, we compared gene expression profiles of human Simpson-Golabi-Behmel syndrome (SGBS) adipocytes under normoxic or hypoxic conditions to detect hypoxia-responsive genes in adipocytes by using whole human genome microarrays.

The effect of hypoxia on gene expression in adipocytes seems to play a central role in this inflammatory response observed in obesity. However, the global impact of hypoxia on transcriptional changes in human adipocytes is unclear. Therefore, we compared gene expression profiles of human Simpson-Golabi-Behmel syndrome (SGBS) adipocytes under normoxic or hypoxic conditions to detect hypoxia-responsive genes in adipocytes by using whole human genome microarrays. Human SGBS adipocytes were cultured in a hypoxic environment (1% O2) for 3, 6 and 16 hours and the control group was cultured under normoxic conditions (21% O2). Total RNA was prepared from control and treated SGBS cells, in triplicate experiments, and probes were hybridized on ‘Human Genome U133 2.0’ arrays (Affymetrix).

Genome-wide discovery and integrative genomic characterization of insulin resistance loci using serum triglycerides to HDL-cholesterol ratio [bulk RNA-seq]

Project description:To investigate gene expression differences during the course of human adipocyte differentiation, we performed differentiation on Human Simpson-Golabi-Behmel syndrome (SGBS) preadipocyte cells following standard protocols (PMID: 20054179). Differentiation begins on day 0 by incubating cells in a serum-free differentiation medium (rosiglitazone, dexamethasone, methylisobuthylxantine, cortisol, transferrin, triiodotyronin, and human insulin). The medium is changed to cortisol, transferrin, triiodotyronin, and human insulin after 4 days.

In depth quantitative proteomic and transcriptomic characterization of human adipocytes differentiation using the SGBS cell line

Project description:Most information on molecular processes accompanying and driving adipocyte differentiation are derived from rodent models. Here, a comprehensive analysis of combined transcriptomic and proteomic alterations during adipocyte differentiation in Simpson–Golabi–Behmel Syndrome (SGBS) cells is provided. The SGBS cells are a well-established and the most widely applied cell model to study human adipocyte differentiation and cell biology. However, the molecular alterations during human adipocyte differentiation in SGBS cells have not yet been described in a combined analysis of proteome and transcriptome. Here a global proteomic and transcriptomic data set comprising relative quantification of a total of 14372 mRNA transcripts and 2641 intracellular and secreted proteins is presented. 1153 proteins and 313 genes are determined as differentially expressed between preadipocytes and the fully differentiated cells including adiponectin, lipoprotein lipase, fatty acid binding protein 4, fatty acid synthase, stearoyl-CoA desaturase, and apolipoprotein E and many other proteins from the fatty acid synthesis, amino acid synthesis as well as glucose and lipid metabolic pathways. Preadipocyte markers, such as latexin, GATA6, and CXCL6, are found to be significantly downregulated at the protein and transcript level. This multi-omics data set provides a deep molecular profile of adipogenesis and will support future studies to understand adipocyte function.

Expression data from female C57BL/6J and B6.Cg-Mir146atm1.1Bal/J mice after 10 weeks of normal or high fat diet

Project description:The pathogenesis of obesity-related metabolic diseases has been linked to the inflammation of white adipose tissue (WAT), but the molecular interconnections are still not fully understood. MiR-146a controls inflammatory processes by suppressing pro-inflammatory signaling pathways. The aim of this study was to characterize the role of miR-146a in obesity and insulin sensitivityresistance . MiR-146a-/- mice were subjected to a high fat diet followed by metabolic tests and WAT transcriptomics. Gain- and loss-of-function studies were performed using human Simpson-Golabi-Behmel syndrome (SGBS) adipocytes. Compared to controls, miR-146a-/- mice gained significantly more body weight on a high fat diet with increased fat mass and adipocyte hypertrophy. This was accompanied by exacerbated liver steatosis, insulin resistance, and glucose intolerance. Likewise, adipocytes transfected with an inhibitor of miR-146a displayed a decrease in insulin-stimulated glucose uptake, while transfecting miR-146a mimics caused the opposite effect. Natriuretic peptide receptor 3 (NPR3) was identified as a direct target gene of miR-146a in adipocytes and CRISPR/Cas9-mediated knockout of NPR3 increased insulin-stimulated glucose uptake and enhanced de-novo lipogenesis. In summary, miR-146a regulates systemic and adipocyte insulin sensitivity via downregulation of NPR3.

Resveratrol-induced changes of the human adipocyte secretion profile.

Project description:Enlarged white adipose tissue (WAT) is a feature of obesity and leads to changes in its paracrine and endocrine function. Dysfunction of WAT cells is associated with obesity associated disorders like type 2 diabetes and cardiovascular diseases. Resveratrol (RSV) a natural polyphenolic compound mimics beneficial effects of calorie restriction. As such, RSV seems a promising therapeutic target for obesity-associated disorders. The effect of RSV on the human adipokine profile is still elusive. Therefore, a proteomic study together with bioinformatical analysis was performed to investigate the effect of RSV on the secretion profile of mature human Simpson-Golabi-Behmel syndrome (SGBS) adipocytes. RSV incubation resulted in elevated basal glycerol release and reduced intracellular TG content. This increased intracellular lipolysis was accompanied by profound changes in the adipocyte secretion profile. Extracellular matrix proteins were down-regulated while processing proteins were mostly up-regulated after RSV treatment. Interestingly, RSV induced secretion of proteins protective against cellular stress and proteins involved in the regulation of apoptosis. Furthermore, we found a RSV-induced up-regulation of adiponectin and ApoE accompanied by a down-regulation of PAI-1 and PEDF secretion which may improve anti-inflammatory processes and increased insulin sensitivity. These effects are beneficial to alleviate obesity-induced metabolic complications. In addition, two novel RSV-regulated adipocyte-secreted proteins were identified.

Open chromatin profiling in adipose tissue marks genomic regions with functional roles in cardiometabolic traits

Project description:Identifying the regulatory mechanisms of genome-wide association study (GWAS) loci affecting adipose tissue has been restricted due to limited characterization of adipose transcriptional regulatory elements. We profiled chromatin accessibility in three frozen human subcutaneous adipose tissue needle biopsies and preadipocytes and adipocytes from the Simpson Golabi-Behmel Syndrome (SGBS) cell strain using an assay for transposase-accessible chromatin (ATAC-seq). We identified 68,571 representative accessible chromatin regions (peaks) across adipose tissue samples (FDR<5%). GWAS loci for eight cardiometabolic traits were enriched in these peaks (p<0.005), with the strongest enrichment for waist-hip ratio. Of 110 recently described cardiometabolic GWAS loci colocalized with adipose tissue eQTLs, 59 loci had one or more variants overlapping an adipose tissue peak. Annotated variants at the SNX10 waist-hip ratio locus and the ATP2A1-SH2B1 body mass index locus showed allelic differences in regulatory assays. These adipose tissue accessible chromatin regions elucidate genetic variants that may alter adipose tissue function to impact cardiometabolic traits.

High throughput analysis of three human adipose cell lines PAZ6, SGBS and SW872

Project description:We report molecular characterization of human brown and white adipocytes. We showed that PAZ6 and SW872 cells exhibit classical molecular and phenotypic markers of brown and white adipocytes, respectively. However, SGBS cells presented a versatile phenotype of adipocyte Sequencing of three human adipocytes cell lines (SGBS, SW872 and PAZ6) in undifferentiated and differentiated stages.

Open chromatin profiling (ATAC-seq) of SGBS human preadipocytes (days 0, 2, 8 and 16 of differentiation to adipocytes) and iPSC-derived hypothalamic neurons (days 12, 16 and 27 of differentiation)

Project description:Human SGBS preadipocytes were differentiated into adipocytes, and human iPSCs were differentiated into hypothalamic neurons. Cells were collected for ATAC-seq at several differentiation stages. The differentiations were performed in one biological replicate, with two technical replicates (different wells of the differentiation that were also processed individually during library preparation). SGBS Day0: Represents the preadipocyte state. SGBS Day2: Represents immature adipocytes. SGBS Day8: Represents early mature adipocytes. SGBS Day16: Represents mature adipocytes. Hypothalamic Day 12: Represents early hypothalamic neurons. Hypothalamic Day 16: Represents mid hypothalamic neurons. Hypothalamic Day 27: Represents mature hypothalamic neurons.
