TranscriptomicsPromoter proximal pausing and its regulation by c-Myc in embryonic stem cells: ChIP-chip
Recruitment of the RNA Polymerase II (Pol II) transcription initiation apparatus to promoters by specific DNA binding transcription factors is well recognized as a key regulatory step in gene expression. We describe here evidence that promoter-proximal pausing is a general feature of transcription ...

GenomicsLigand-dependent dynamics of retinoic acid receptor binding during early neurogenesis
Among its many roles in development, retinoic acid determines the anterior-posterior identity of differentiating motor neurons by activating Retinoic Acid Receptor (RAR)-mediated transcription. RAR is thought to bind the genome constitutively, and only induce transcription in the presence of the ret...

GenomicsDivergent transcription from active promoters
Here we describe a novel class of short RNAs and high-resolution ChIP-Seq data that together indicate widespread divergent transcription at mammalian promoters and suggest the existence of novel regulatory mechanisms concerning both initiation and elongation by RNA polymerase II. ChIP-seq in murine ...

MetabolomicsThe dynamic clustering of insulin receptor underlies its signaling and is disrupted in insulin resistance
Insulin receptor (IR) signaling is central to normal metabolic control and is dysregulated in metabolic diseases such as type 2 diabetes. We report here that IR is incorporated into dynamic clusters at the plasma membrane, in the cytoplasm and in the nucleus of human hepatocytes and adipocytes. Insu...

GenomicsExpression, ChIP-chip, and ChIP-Seq data from REH and SEM leukemia cell lines [ChIP-Seq]
MLL-fusion proteins are potent inducers of cancer in hematopoietic cells, where they are known to cause changes in global gene expression. How MLL-fusion proteins interact with the genome has not been established, so we have limited understanding of the pathway by which these proteins generate aberr...

GenomicsCore transcriptional regulatory circuit controlled by the tal1 complex in human t-cell acute lymphoblastic leukemia (Subseries)
The oncogenic transcription factor TAL1/SCL is aberrantly overexpressed in over 40% of cases of T-cell acute lymphoblastic leukemia (T-ALL), emphasizing the importance of the TAL1-regulated transcriptional program in the molecular pathogenesis of T-ALL. Here we identify the core transcriptional regu...

GenomicsEmbryonic stem cell based system for the discovery and mapping of developmental transcriptional programs
Chromatin immunoprecipitation followed by deep sequencing (ChIP-seq) is the method of choice to study function of transcription factors in cell fate determination. This technique faces two major obstacles when applied to developmental studies: the availability of ChIP grade antibodies and access to ...

GenomicsChromatin Structure and Gene Expression Programs of Human Embryonic and Induced Pluripotent Stem Cells (ChIP-seq)
Knowledge of both the global chromatin structure and the gene expression programs of human embryonic stem (ES) cells and induced pluripotent stem (iPS) cells should provide a robust means to assess whether the genomes of these cells have similar pluripotent states. Recent studies have suggested tha...

GenomicsSetDB1 Contributes to Repression of Genes Encoding Developmental Regulators and Maintenance of ES Cell State
Transcription factors that play key roles in regulating embryonic stem (ES) cell state have been identified, but the chromatin regulators that help maintain ES cells are less well understood. A high-throughput shRNA screen was used to identify novel chromatin regulators that influence ES cell state...
