(Submitter supplied) PPARγ promotes adipogenesis while Wnt proteins inhibit adipogenesis. However, the mechanisms that control expression of these positive and negative master regulators of adipogenesis remain incompletely understood. By genome-wide histone methylation profiling in preadipocytes, we find that among gene loci encoding adipogenesis regulators, histone methyltransferase (HMT) G9a-mediated repressive epigenetic mark H3K9me2 is enriched on the entire PPARγ locus. more...

(Submitter supplied) PA1 has been identified as a component of a MLL3/4-containing histone methyltransferase complex. PA1 directly interacts with PTIP but not with other complex components. Since biological functions of PA1 are unknown, we used microarrays to determine which genes are regulated by PA1.

(Submitter supplied) Peroxisome proliferator-activated receptor γ (PPARγ) is the master regulator of adipocyte differentiation and is closely linked to the development of obesity. Despite a large progress on the transcriptional network of PPARγ, the epigenetic regulation associated with histone modification remains elusive. Here, we found that CDK2-associated cullin 1 (CACUL1), identified as a novel SIRT1 interacting protein, directly binds to PPARγ through the CoRNR box 2 and represses the transcription activity and adipogenic potential of PPARγ. more...

(Submitter supplied) PPARg and C/EBPa cooperate to control preadipocyte differentiation (adipogenesis). However, the factors that regulate PPARg and C/EBPa expression during adipogenesis remain largely unclear. Here we show PTIP, a protein that associates with histone H3K4 methyltransferases, regulates PPARg and C/EBPa expression in mouse embryonic fibroblasts (MEFs) and during preadipocyte differentiation. PTIP deletion in MEFs leads to marked decreases of PPARg expression and PPARg-stimulated C/EBPα expression. more...

(Submitter supplied) The Wnt/b-catenin signaling inhibits adipogenesis. Genome-wide profiling studies have revealed the enrichment of histone H3K27 methyltransferase PRC2 on Wnt genes. However, the functional significance of such a direct link between the two types of developmental regulators in mammalian cells, and the role of PRC2 in adipogenesis, remain unclear. Here we show PRC2 and its H3K27 methyltransferase activity are required for adipogenesis. more...

Analysis of preadipocytes deficient in Ezh2, the enzymatic subunit of H3K27 methyltransferase PRC2. Deletion of Ezh2 eliminates H3K27me3 on Wnt promoters leading to activation of Wnt/b-catenin signaling and inhibition of adipogenesis. Results provide insight into the role of PRC2 in adipogenesis.

(Submitter supplied) Histone tails are post-translationally modified at multiple sites, including Lys36 on histone H3 (H3K36). The H3K36 methylation has been shown to associate with the transcription of active euchromatin, alternative splicing, DNA repair and recombination. However, the role of H3K36 methylation during cell differentiation is still obscure.Previous investigations found that a site specific Lys-to-Met mutation on histones can serve as an inhibitor of this site specific methyltransferases to repress global methylation on that lysine of histones. more...

(Submitter supplied) We attempted to analyze the effect of PRMT1 knockdown in adipogenesis.3T3-L1 preadipocytes were used to investigate aipogenesis in vitro. Analysis of the transcriptomics from siNC and siPRMT1 3T3-L1 cells at MDI induction for 24 h and 72 h provides new insight into the collective roles of PRMT1 in mitotic clonal expansion and adipocyte differentiation.

(Submitter supplied) To investigate the cooperative function KDM4D/NFIB/MLL1 complex in the regulation of adipogenic differentiation, we established 10T1/2 cell lines in which each target gene has been knocked down by shRNA. We then performed gene expression profiling analysis using data obtained from RNA-seq of 4 different cells at two time points.

(Submitter supplied) 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. more...

(Submitter supplied) The three dimensional folding of mammalian genomes is cell-type specific and hard to convert suggesting that it is an important layer of gene regulation. Analysis of genome-wide chromosomal associations revealed adipogenesis-specific spatial clustering of adipogenic genes in 3T3-L1 cells. High temporal resolution analysis revealed that the adipogenic "hub", sampled by pparg and Lpin1, undergoes orchestrated reorganization along adipogenesis. more...

(Submitter supplied) Here we have employed chromatin immunoprecipitation combined with deep sequencing to map and compare PPARγ binding in in vitro differentiated primary mouse adipocytes isolated from epididymal, inguinal, and brown adipose tissues. While these PPARγ binding profiles are overall similar, there are clear depot-selective binding sites. Most PPARγ binding sites previously mapped in 3T3-L1 adipocytes can also be detected in primary adipocytes, but there are a large number of PPARγ binding sites that are specific to the primary cells, and these tend to be located in closed chromatin regions in 3T3-L1 adipocytes. more...

(Submitter supplied) Dexamethasone (DEX), a synthetic ligand for glucocorticoid receptor (GR), is routinely used to stimulate adipogenesis in culture. GR-depleted preadipocytes show adipogenesis defects one week after induction of differentiation. However, it has remained unclear whether GR is required for adipogenesis in vivo. By deleting GR in precursors of brown adipocytes, we found unexpectedly that GR is dispensable for brown adipose tissue development in mice. more...
