LSD1 knockdown in 3T3-L1 preadipocytes

Project description:Obesity is often associated with a low-grade systemic inflammation state that contributes to the development of insulin resistance and atherosclerotic complications. This is usually coupled with increased macrophage infiltration in the adipose tissue and a defect in adipocyte differentiation that results in accumulation of hypertrophic fat cells characterized by a deregulated pattern of adipokine expression. Here we show that knockdown of histone demethylase lsd1 in 3T3-L1 preadipocytes results in defective adipogenesis and derepression of an inflammatory program in these cells. The dataset consists of four sample groups: [1] 3T3-L1 preadipocytes (passage 19) transfected with a control scrambled siRNA at 24h after transfection (siC.24h), [2] 3T3-L1 preadipocytes (p.19) transfected with a siRNA directed against LSD1 at 24h after transfection (siLsd1.24h), [3] 3T3-L1 preadipocytes (p.21) transfected with a control scrambled siRNA at 48h after transfection (siC.48h), and [4] 3T3-L1 preadipocytes (p.21) transfected with a siRNA directed against LSD1 at 48h after transfection (siLsd1.48h). The 24h sample groups (siC.24h and siLsd1.24h) consist of two biological replicate samples; the 48h sample groups (siC.48h and siLsd1.48h) consist of three biological replicate samples. Each sample was hybridized to a separate array, for a total of ten arrays.

Gene expression signatures in IRF7 overexpressed 3T3-L1 adipocytes

Project description:To identify the genes that are regulated by IRF7, we have performed DNA microarray in 3T3-L1 adipocytes differentiated from precursor cells infected with retrovirus empty or carrying IRF7. Plasmids (Empty- and IRF7-pMSCV) were kindly provided from Dr. Eguchi at the Okayama University Graduate School of Medicine, Okayama, Japan [Cell Metab. 2008;7: 86-94.]. Infected 3T3-L1 preadipocytes were selected by puromycin treatment and differentiated into adipocytes. 7 days after the induction of adipogenesis, total RNA was isolated.

RNA-sequencing of control (CTL), MLKL -/- (MLKL) and RIPK3-/- (RIPK3) 3T3-L1 preadipocytes (J0) or differentiated (J7) cells.

Project description:Purpose: Necroptosis as been implicated in various deseases. The goal of this study is to invastigate the impact of RIPK3 and MLKL in the lipid metabolism of adipocytes. Methods: 3T3-L1 preadipocytes invalidated or not for RIPK3 or MLKL were exposed differenciated into mature adipocytes and the mRNA profiles of wild type (WT), RIPK3-/- knockout (RIPK3-KO) or MLKL-/- knockout 3T3-L1 cells control (J0) or differenciated into mature adipocytes (J7) were generated by deep sequencing, in 3 copies, using Illumina NOVAseq 6000 plateform. Differential expression analysis between two conditions/groups (five biological replicates per condition) was performed using DESeq2 R package. Genes with an adjusted P value < 0.05 found by DESeq2 were assigned as differentially expressed. qRT–PCR validation was performed using SYBR Green assays Results: The DEGs were clustered using a hierarchical clustering algorithm, and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis unveiled a clear reduction in the expression of genes involved in the early or late stages of adipogenesis in MLKL-KO cells Conclusions: Taken together, these data suggest that Mlkl but not Ripk3 deficiency impaired adipogenesis of 3T3-L1 cells by reducing the expression of pro-adipogenic factors and genes involved in fatty acid metabolism.

Gene expression data from pre-adipocytes 3T3-L1 treated with Tsuruazuki Extract (Tsuru)

Project description:Gene expression profiling of pre-adipocytes 3T3-L1 reveals anti-adipogenic potential to metabolic associated diseases through whole transcriptomic analysis. We evaluated the effects of Tsuruazuki extract on pre-adipocytes 3T3-L1. We performed an untargeted whole-genome transcriptome analysis to explore functionality of Tsuru on 3T3-L1 cells.

Expression data from 3T3-L1 preadipocytes and 10Thalf mesenchymal stem cells

Project description:Bivalent H3K4me3 and H3K27me3 chromatin domains in embryonic stem cells keep active developmental regulatory genes expressed at very low levels and poised for activation. Here, we show an alternative and previously unknown bivalent modified histone signature in lineage-committed mesenchymal stem cells and preadipocytes that pairs H3K4me3 with H3K9me3 to maintain adipogenic master regulatory genes (Cebpa and Pparg) expressed at low levels yet poised for activation when differentiation is required. We show lineage-specific gene-body DNA methylation recruits H3K9 methyltransferase SETDB1 which methylates H3K9 immediately downstream of transcription start sites marked with H3K4me3 to establish the bivalent domain. At the Cebpa locus, this prevents transcription factor C/EBPÎ² binding, histone acetylation, and further H3K4me3 deposition and is associated with pausing of RNA polymerase II, which limits Cebpa gene expression and adipogenesis. We used microarrays to detail the global programme of gene expression in 3T3-L1 preadipocytes and 10Th1lf mesenchymal stem cells and identified up-regulated genes upon knockdown of SETDB1, MBD1, and MCAF1. SETDB1, MBD1, or MCAF1 was knocked-down in 3T3-L1 preadipocytes and 10Thalf mesenchymal stem cells for RNA extraction and hybridization on Affymetrix microarrays. Small interfering RNAs (siRNA) targeting to Setdb1, Mbd1, or Mcaf1 was transfected to 3T3-L1 preadipocytes or 10Thalf mesenchymal stem cells.
