MicroRNA expression profiling of human adipose stromal cell (hASC) adipogenesis

ABSTRACT: Human abdominal adipose tissue was obtained with informed consent from a 33-year old Caucasian female (BMI = 32.96 Kg/m2) undergoing lipoaspiration. Adipose stromal cells (hASCs) were isolated and differentiated into adipocytes in vitro. Two technical replicates from 9 time points relative to induction of adipogenesis (day 0). Also, one sample from pre-adipocytes (day -2) grown without FGF.

We report the generation and comparative analysis of genome-wide chromatin state maps, PPARγ and CTCF localization maps, and gene expression profiles from murine and human models of adipogenesis. The data provide high-resolution views of chromatin remodeling during cellular differentiation and allow identification of thousands of putative preadipocyte- and adipocyte-specific cis-regulatory elements based on dynamic chromatin signatures. We find that the specific locations of most such elements d ...[more]

Expression data from SGBS human cells before and after 24 hours of stimulation with differentiation cocktail, with or without Scrambled (Scr) or Tenomodulin (TNMD) siRNA to knockdown the genes of interest.

Project description:In a screen for upregulated adipocyte genes in insulin resistant versus insulin sensitive subjects matched for BMI, we identified the type II transmembrane protein tenomodulin (TNMD), previously implicated in glucose tolerance in gene association studies. TNMD expression was greatly increased in human preadipocytes during differentiation, while silencing TNMD blocked adipogenic gene induction and adipogenesis. We used microarrays to identify genes of interest that are differentially expressed after the addition of siRNA to tenomodulin or scrambled siRNA, in both preadipocytes and partially differentiated adipocytes. SGBS preadipocytes were treated with scrambled or siTNMD. Cells either were kept undifferentiated or stimulated for 24 hours with differentiation cocktail. Cells were prepared with this protocol on three different occasions and total RNA was isolated to provide three biological replicates per sample.

Long non-coding RNAs regulate adipogenesis (Illumina RNA-Seq)

Project description:Adipogenesis involves the regulation of hundreds of genes by several well-studied proteins, but the role of long, noncoding RNAs in this process has not been defined. We track the regulation of hundreds of lncRNAs during adipocyte differentiation, and find several that are essential for this process. We extractedbrown and white primary adipocytes and pre-adipocytes and profiled lncRNA expresssion via mRNA-Seq. We also profiled cultured, differentiated adipocytes to verify that we could recapitulate the adipocyte expression profile in preparation for a loss-of-function screen for essential adipogenic lincRNAs.

3T3-L1

Project description:Obesity is an energy balance disorder in which nutrient intake chronically exceeds energy expenditure, resulting in the accumulation of white adipose tissue. Increased adiposity is due to increases in the number and size of adipocytes, which leads to increased body fat and metabolic consequences. Adipocytes induce insulin resistance by promoting lipotoxicity and modulating adipokine secretion. Therefore, a thorough understanding of the mechanisms that regulate adipogenesis could have clinical relevance in preventing and treating obesity and the metabolic syndrome. In this study, we performed miRNA array to measure miRNA profiles of undifferentiated and differentiated 3T3-L1 adipocytes using Agilent(r) miRNA array. We show that miRNA profile changes during adipogenesis. Thus, this data would be useful to find the distinct role of miRNAs for the regulation of adipogenesis.

Gene expression data of brown-like adipocytes from Lgr4 homozygous mutant SVF

Project description:Obesity has become a global health problem. Brown adipose tissue (BAT), specialized for energy expenditure through thermogenesis, potently counteracts obesity. Recently, BAT is also identified in human adults. We found that Lgr4 homozygous mutant (Lgr4m/m) mice display reduced adiposity and exhibit brown-like adipocytes in their WAT depots with higher expression of uncoupling protein 1 (Ucp1). Furthermore, Lgr4 ablation potentiates brown adipocyte differentiation from stromal vascular fraction (SVF) of epididymal WAT (eWAT) in vitro. We used microarrays to emxamine the gene expression profiles of the brown-like adipocytes differentiated from SVF of wild-type and Lgr4 mutant mice. We identified distinct gene expression profiles of these two groups. To demonstrate Lgr4 ablation can potentiate the differentiation of SVF from eWAT toward brown-like adipocytes in vitro, we isolated SVF from epididymal white adipose tissue (eWAT) of wild-type (WT) and Lgr4 mutant mice. We then plated SVF cells in 12-well plate, and differentiated them to brown adipocytes, followed by RNA extraction and hybridization with Affymetrix microarrays.
