Integrated analysis of transcript level regulation of metabolism during human adipocyte differentiation [time course]

ABSTRACT: Here, we have focused on studying the link between metabolic changes driven by the differentiation into mature adipocytes of a human preadipocyte cell line (SGBS) and their regulation, through a combined experimental and computational approach. By collecting data on gene expression, PPARg, CEBPa, LXR and H3K4me3 genome-wide ChIP-seq profles and transcriptome-wide microRNA target identification for miR-27a, miR29a and miR-222, and using constraint-based modeling to estimate metabolic reaction activity, we obtained a comprehensive set of information highlighting how epigenetic, transcriptional and post-transcriptional regulation impacts the metabolic network. Illumina HT12 microarrays: Time series of differentiation (20 samples, 7 time points in duplicate or triplicate) This is the Illumina Gene Expression part of the study.

Metabolic diseases and comorbidities represent an ever-growing epidemic where multiple cell types impact tissue homeostasis. Here, the link between the metabolic and gene regulatory networks was studied through experimental and computational analysis. Integrating gene regulation data with a human metabolic network prompted the establishment of an open-sourced web portal, IDARE (Integrated Data Nodes of Regulation), for visualizing various gene-related data in context of metabolic pathways.

Microarray analyses of the effects of prenatal metformin exposure on the gene expression profile of liver, brain and subcutaneous adipose tissue of neonatal mice

Project description:The aim of the study was to characterise the effects of prenatal metformin exposure on a tissue gene expression level in mice. The data consists of two models, regular diet (study I) and high fat diet (study II) model. In both models, metformin (300 mg/kg) or control agent (water) was administered to pregnant female mice from the embryonic day E0.5 untill E17.5. In the high fat diet model, the dams had been on a high fat diet (60% of fat) for one month prior to and during the gestation. The diet was changed to regular diet from E18.5. The pups were sacrificed by decapitation at postnatal day 4 and brain (study I), liver (studies I and II) and subcutaneous adipose tissue (study II) were taken for further microarray analyses. In study I,there are 3 replicates in each group of interest: brain_male_ctrl; brain_male_met; liver_male_ctrl; liver_male_met; liver_female_ctrl; liver_female_met. In study II, there are 6 replicates in each group of interest: liver_male_ctrl; liver_male_met; wat_male_ctrl; wat_male_met.

Genome-wide analysis of PIAS1 on AR gene expression in MDA-MB453

Project description:The majority of breast cancer subtypes express androgen receptor (AR) in addition to estrogen receptor Î± (ERÎ±). Depending on the breast cancer subtype androgen signaling has either stimulatory or inhibitory roles in breast cancer cell growth. We have mapped AR cistrome in ERÎ± negative human molecular apocrine breast cancer MDA-MB453 cells and analyzed it in relation to the androgen-regulated transcriptome in the same cells. We have also examined the effect of silencing of the coregulator SUMO ligase PIAS1 on the androgen-regulated transcriptome and AR cistrome in MDA-MB453 cells. Our results show that the MDA-MB453 cells share with VCaP prostate cancer cells a core AR cistrome and target gene signature linked to cancer cell growth and that PIAS1 acts as an AR target gene-selective coregulator in MDA-MB453 cells. MDA-MB453 cells were transfected with control siRNA (siNON) or PIAS1 siRNA (siPIAS1) for 72 h and treated 16 h with 10 nM R1881 or vehicle (ethanol). Total RNA was isolated and biological triplicate samples were analyzed by microarray.

Genome-wide analysis of androgen receptor (AR) SUMOylation effects on gene expression (PC-3).

Project description:Androgen receptor (AR) plays an important regulatory role during prostate cancer development. ARM-bM-^@M-^Ys transcriptional activity is regulated by androgenic ligands, but also by post-translational modifications. To study the role of the AR SUMOylation in genuine chromatin environment, we compared androgen-regulated gene expression and AR chromatin occupancy in PC-3 prostate cancer and HEK293 cell lines stably expressing wild-type (wt) or SUMOylation site-mutated AR (AR-K386R,K520R). Our genome-wide gene expression analyses reveal that the SUMOylation modulates the AR function in a target gene and pathway selective manner. The transcripts that are differentially regulated by androgen and SUMOylation are linked to cellular movement, cell death, cellular proliferation, cellular development and cell cycle. In line with these data, SUMOylation mutant AR cells proliferate faster and are more sensitive to apoptosis. Moreover, ChIP-seq analyses show that the SUMOylation modulates the chromatin occupancy of AR on many loci in a fashion that parallels with their differential androgen-regulated expression. De novo motif analyses show that other transcription factor-binding motifs are differentially enriched at the wtAR- and the AR-K386R,K520R-preferred genomic binding positions. Taken together, our data indicate that SUMOylation does not simply repress the AR activity, but it regulates ARM-bM-^@M-^Ys interaction with the chromatin and the receptorM-bM-^@M-^Ys target gene selection. PC-3 cells stably expressing wild-type AR (wtAR) or SUMOylation-defective AR (AR-K2R) were treated 16 h with 10 nM R1881 or vehicle (EtOH). All conditions were performed in triplicate. The effect on gene expression was assessed by microarray.

Microarray analysis of human monocytic THP-1 cell treated with 1Î±,25-dihydroxyvitamin D3 or Trichostatin A and the combination of both

Project description:The nuclear hormone 1Î±,25-dihydroxyvitamin D3 (1Î±,25(OH)2D3) regulates its target genes via activation of the transcription factor vitamin D receptor (VDR) far more specifically than the chromatin modifier trichostatin A (TsA) via its inhibitory action on histone deacetylases. We selected the thrombomodulin gene locus with its complex pattern of three 1Î±,25(OH)2D3 target genes, five VDR binding sites and multiple histone acetylation and open chromatin regions as an example to investigate together with a number of reference genes, the primary transcriptional responses to 1Î±,25(OH)2D3 and TsA. Transcriptome-wide, 18.4% of all expressed genes are either up- or down-regulated already after a 90 min TsA treatment; their response pattern to 1Î±,25(OH)2D3 and TsA sorts them into at least six classes. TsA stimulates a far higher number of genes than 1Î±,25(OH)2D3 and dominates the outcome of combined treatments. However, 200 TsA target genes can be modulated by 1Î±,25(OH)2D3 and more than 1000 genes respond only when treated with both compounds. The genomic view on the genes suggests that the degree of acetylation at transcription start sites and VDR binding regions may determine the effect of TsA on mRNA expression and its interference with 1Î±,25(OH)2D3. Our findings may have implications on dual therapies using chromatin modifiers and nuclear receptor ligands. All conditions are performed in triplicate: one time point with TsA treatment and vehicle control and one time point with TsA, 1Î±,25-dihydroxyvitamin D3, the combination of both and vehicle

By collecting data on gene expression, PPARg, CEBPa, LXR and H3K4me3 genome-wide ChIP-seq profles and transcriptome-wide microRNA target identification for miR-27a, miR29a and miR-222, and using constraint-based modeling to estimate metabolic reaction activity, we obtained a comprehensive set of information highlighting how epigenetic, transcriptional and post-transcriptional regulation impacts the metabolic network. Illumina Solexa sequencing: Six samples in total. Two ChIP-seq samples were prepared using an antibody against H3K4me3 active TSS chromatin marker from human SGBS preadipocyte and day 10 differentiated SGBS adipocyte cells. From day 10 differentiated SGBS cells additional three samples were prepared using an antibody against PPARg, CEBPa and LXRa to determine their genome-wide binding. One input control sample is included.
