GenomicsHuman variation in PolII and NF-KappaB binding (ChIP-seq study with NF-KappaB)
We examined genome-wide variation in transcription factor binding in different individuals and a chimpanzee using chromatin immunoprecipitation followed by massively-parallel sequencing (ChIP-Seq). The binding sites of RNA Polymerase II (Pol II) as well as a key regulator of immune responses, NFkB, ...

GenomicsThe DAXX co-repressor is directly recruited to active regulatory elements genome-wide to regulate autophagy programs in a model of human prostate cancer (ChIP-seq)
This study was aimed at understanding the genome-wide binding and regulatory role of the DAXX transcriptional repressor, recently implicated in PCa. ChIP-Seq analysis of genome-wide distribution of DAXX in PC3 cells revealed over 59,000 DAXX binding sites, found at regulatory enhancers and promoters...

TranscriptomicsMLL and Pol2 Chip-chip in interphase and mitotic arrested cells
Mixed Lineage Leukemia (MLL) and its metazoan Trithorax orthologs have been linked with the epigenetic maintenance of transcriptional activity. To identify mechanisms by which MLL perpetuates active transcription in dividing cells, we investigated its role during M-phase of the cell cycle. Unlike ot...

TranscriptomicsPedigreed Primate Embryonic Stem Cells Express Homogeneous Familial Gene Profiles
Pedigreed primate ESCs display homogeneous and reliable expression profiles. These similarities to mouse ESCs suggest that heterogeneities found among hESCs result from their disparate origins rather than intrinsic biological limitations with primate embryonic stem cells. Keywords: different nhpESC ...

TranscriptomicsMLL1 is essential for the senescence-associated secretory phenotype [RNA-Seq]
Oncogene-induced senescence (OIS) and therapy-induced senescence (TIS), while tumor-suppressive, also promote procarcinogenic effects by activating the DNA damage response (DDR), which in turn induces inflammation. This inflammatory response prominently includes an array of cytokines known as the se...

GenomicsFOXM1 Cistrome Predicts Breast Cancer Metastatic Outcome Better Than FOXM1 Expression Levels or Tumor Proliferation Index [ChIP-Seq]
FOXM1 is a key transcription factor regulating cell cycle progression, DNA damage response, and a host of other hallmark cancer features, but the role of the FOXM1 cistrome in driving estrogen receptor-positive (ER+) vs. ER- breast cancer clinical outcomes remains undefined. Chromatin immunoprecipit...

GenomicsPromoter proximal pausing and its regulation by c-Myc in embryonic stem cells: ChIP-Seq
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 ...

TranscriptomicsRecapitulation of human premature aging by using iPSCs from Hutchinson-Gilford progeria syndrome
Hutchinson-Gilford progeria syndrome (HGPS) is a rare and fatal human premature aging disease1-5, characterized by premature atherosclerosis and degeneration of vascular smooth muscle cells (SMCs)6-8. HGPS is caused by a single-point mutation in the LMNA gene, resulting in the generation of progerin...

GenomicsThe long noncoding RNAs NEAT1 and MALAT1 bind active chromatin sites
Long noncoding RNAs (lncRNAs) are important regulators of chromatin; however, the mechanistic roles for many lncRNAs are poorly understood in part because their direct interactions with genomic loci and proteins are difficult to assess. We used CHART-seq to map the genomic binding sites for two high...
