(Submitter supplied) Master transcription factors are the gatekeepers of lineage identity. As such, they have been a major focus of efforts to manipulate cell fate for therapeutic purposes. The ETS transcription factor PU.1 has a potent ability to confer macrophage phenotypes on cells already committed to a different lineage, but how it overcomes the presence of other master regulators is not known. The nuclear receptor PPARγ is the master regulator of the adipose lineage, and its genomic binding pattern is well characterized in adipocytes. more...

(Submitter supplied) The nuclear receptor Peroxisome Proliferator Activator Receptor (PPAR ) is the target of antidiabetic thiazolidinedione drugs, which improve insulin resistance but have side-effects that limit widespread use. PPAR is required for adipocyte differentiation, but is also expressed in other cell types, notably macrophages, where it influences atherosclerosis, insulin resistance, and inflammation. A central question is whether PPAR binding in macrophages occurs at the same or different genomic locations compared to adipocytes. 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) The nuclear receptor PPAR gamma is required for adipocyte differentiation, but its role in mature adipocytes is less clear. Here we report that knockdown of PPAR gamma expression in 3T3-L1 adipocytes returned the expression of most adipocyte genes towards preadipocyte levels. Consistently, down regulated but not up regulated genes showed strong enrichment of PPAR gamma binding. Surprisingly, not all adipocyte genes were reversed and the adipocyte morphology was maintained for an extended period after PPAR gamma depletion. more...

(Submitter supplied) We profiled PPARg dependent gene expression changes during differntiation of 3T3L1 cell using PPARg siRNA 3T3-L1 (Pre-adipocyte) cell line was induced to differentiate using standard adipocyte differentiation media (IBMX, Dex and Insulin) 48hrs post-confluency. RNA was harvested at day -2 (confluent fibroblasts), 48hrs post-induction with IBMX, DEX and Insulin (day=0) and for each subsequent day after rosiglitazone treatment. more...

(Submitter supplied) Here we report, for the first time, the acute effects of the synthetic PPARγ agonist rosiglitazone on the transcriptional network of PPARγ in adipocytes. Treatment with Rosiglitazone for 1 hour leads to acute transcriptional activation as well as repression of a number of genes as determined by genome-wide RNA polymerase II occupancy. Unlike what has been shown for many other nuclear receptors, agonist treatment does not lead to major changes in the occurrence of PPARγ binding sites. more...

(Submitter supplied) Obesity due to overnutrition causes adipose tissue dysfunction, serving as a critical pathological step on the road to Type 2 diabetes (T2D) and other metabolic disorders. Here, we performed an unbiased investigation into the fundamental molecular mechanisms by which adipocytes transition to an unhealthy state during obesity. We fed NuTRAP (Nuclear tagging and Translating Ribosome Affinity Purification) mice crossed with Adipoq-Cre with chow or high fat diet (HFD) for 10 weeks and determined adipocyte-specific transcriptomic profiles by RNA-seq, active promoter and enhancer activities by H3K27ac ChIP-seq, and the PPARg cistrome by ChIP-seq. more...

(Submitter supplied) Cellular differentiation is regulated through activation and repression of defined transcription factors. A hallmark of differentiation is a pronounced change in cell shape, which is determined by dynamics of the actin cytoskeleton. In de-differentiated fat (DFAT) cells and 3T3-L1 cells, we showed that treatment with the ROCK inhibitor Y-27632, by inducing remodeling of the actin cytoskelton, causes adipocyte differentiation. more...

(Submitter supplied) Genome-wide comparisons of transcription factor binding sites in different species allow for a direct evaluation of the evolutionary constraints that shape transcription factor binding landscapes. To gain insights into the evolution of the PPARg-dependent transcriptional network, we obtained binding data for PPARg, RXR and PU.1 in human macrophages and compared the profiles to matching data from mouse macrophages (Lefterova et al. more...

(Submitter supplied) The majority of sequence-specific transcription factors bind genomic DNA only at a fraction of their potential binding sites and the ‘rules’ for binding or not-binding are only partially understood. Here, we studied the binding properties of the myeloid and B-cell specific transcription factor PU.1 in-vivo and in-vitro to unveil basic features of occupied vs. non-occupied consensus sites. In addition to published PU.1 ChIP-seq data we mapped CTCF binding sites in monocytes and macrophages to determine chromatin domain boundaries and performed MCIp-seq in monocytes to reveal DNA methylation patterns across the genome.

(Submitter supplied) To guarantee blood supply throughout adult life hematopoietic stem cells (HSCs) need to carefully balance between self-renewing cell divisions and quiescence. Identification of genes controlling HSC self-renewal is of utmost importance given that HSCs are the only stem cells with broad clinical applications. Transcription factor PU.1 is one of the major regulators of myeloid and lymphoid development. more...

(Submitter supplied) Here, we investigated the role of adipocyte PU.1 in the development of age-associated metabolic syndrome. We generated mice with adipocyte specific PU.1 knockout, assessed metabolic changes in young and aged PU.1fl/fl (control) and AdipoqCre PU.1fl/fl(aPU.1KO) mice, including body weight, body composition, energy expenditure and glucose homeostasis. We also performed transcriptional analyses using RNA-Sequencing of adipocytes from these mice.
