(Submitter supplied) Cyclic regulatory systems are ubiquitous in cells and tissues. In the liver rhythms in mRNA expression are determined by the homeostatic regulation that operates on daily circumstances. In particular the specific response to nutrients, as well as systemic and peripheral circadian oscillators, contribute to the set up of the hepatic homeostasis at different phases of the day. In this series we used microarrays to detail the global program of gene expression in the mouse liver under physiological daily variations, determined by both the feeding and the circadian cycles.

(Submitter supplied) To understand the transcriptional basis of circadian rhythms in mouse liver, we generated genome-wide profiles of RNA polymerase II (Pol 2) DNA occupancy and the histone modifications H3K4me3 and H3K36me3 around the circadian cycle. We found that Pol 2 occupancy at promoters and in gene bodies cycle in synchrony, suggesting that Pol 2 recruitment at promoters underlies circadian gene transcription. On average, Pol 2 occupancy precedes mRNA accumulation by about three hours. Promoters of transcribed genes have tri-methylated H3K4 residues even at their trough activity times, and the tri-methylation levels increase in phase with Pol 2 loading. In contrast, the tri-methylation of H3K36 residues lags transcription by three hours with amplitudes that are markedly shallower, indicating that this mark is less dynamic on the circadian time scale. The comparison of Pol 2 occupancy and mRNA accumulation revealed that both transcriptional and post-transcriptional regulatory mechanisms can account for diurnal mRNA profiles.

(Submitter supplied) It is unclear how epigenetic changes regulate the induction of erythroid-specific genes during terminal erythropoiesis. Here we use global mRNA sequencing (mRNA-seq) and chromatin immunoprecipitation coupled to high-throughput sequencing (CHIP-seq) to investigate the changes that occur in mRNA levels, RNA Polymerase II (Pol II) occupancy and multiple post-translational histone modifications when erythroid progenitors differentiate into late erythroblasts. more...

(Submitter supplied) Here we globally analyzed mRNA and epigenetic changes in both early erythroid progenitors and late erythroblasts. Concomitant with gene induction there was an increase in RNA Pol II binding and activation marks near the transcriptional start site (TSS) and the elongation mark H3K79me2 (but not H3K36me3),both near the TSS and along the full gene length. In contrast, most repressed genes became depleted of elongation marks. more...

This data set includes analysis of the 3hr time point in cells infected in the presence of cycloheximide and the 6hr time point in cells infected in the presence of phosphonoacetic acid, flavopiridol and acyclovir. We have compared the data set to a cytoplasmic mRNA seq data set which is also included. more...

(Submitter supplied) The transition from transcription initiation to elongation is a key regulatory step in gene expression, which requires RNA polymerase II (Pol II) to escape promoter proximal pausing on chromatin. While elongation factors promote pause release leading to transcription elongation, the role of epigenetic modifications during this critical transition step is poorly understood. Two histone marks on histone H3, lysine 4 trimethylation (H3K4me3) and lysine 9 acetylation (H3K9ac), co-localize on active gene promoters and are associated with active transcription. more...

(Submitter supplied) Purpose: To identify the differential transcriptional patterns during postnatal cardiac growth, pressure-induced cardiac hypertrophy and adult mouse hearts Results: Our data revealed novel transcriptional patterns during cardiac growth conditions. The results showed that most of the essential genes are regulated by promoter clearance of paused RNA pol II, while de novo recruitment is required for regulation of mostly speclaized genes during cardiac growth. more...

(Submitter supplied) Purpose: We used ChIP-seq to analyze daily transcription and regulation of Pol II pausing within the mouse liver. Methods: Livers of young mice were processed for Pol II and Nelf-A ChIP-seq at 4-h interval across the day. The binding pattern was analyzed by MACS. Tag pileup within promoter and gene body regions were also obtained to calculate Pol II TR. Results: We obtained > 10 million high quality sequencing reads per time points per sample after quality control and alignments. more...

(Submitter supplied) A large body of literature suggests that local features of chromatin are crucial in determining functional properties of underlying DNA. The extent to which DNA sequence plays an active role in the establishment and maintenance of patterns of histone and DNA modification at promoters in cells and tissues in an adult animal remains poorly understood. Likewise, whether passage through development is required for refinement of transcriptional states and chromatin marks characteristic of fully differentiated adult cells remains unclear. more...

(Submitter supplied) Recent genome-wide chromatin immunoprecipitation coupled high throughput sequencing (ChIP-seq) analyses performed in various eukaryotic organisms, analysed RNA Polymerase II (Pol II) pausing around the transcription start sites of genes. In this study we have further investigated genome-wide binding of Pol II downstream of the 3' end of the annotated genes (EAGs) by ChIP-seq in human cells. At almost all expressed genes we observed Pol II occupancy downstream of the EAGs suggesting that Pol II pausing 3' from the transcription units is a rather common phenomenon. more...

(Submitter supplied) Using pol II mutants in human cells we found that slow transcription repositioned specific co-transcriptionally deposited chromatin modifications; H3K36me3 shifted within genes toward 5’ ends and H3K4me2 extended further upstream of start sites. Slow transcription also evoked a hyperphosphorylation of CTD Ser2 residues at 5’ ends of genes that is conserved in yeast. We propose a “dwell-time in the target zone” model to explain the effects of transcriptional dynamics on establishment of co-transcriptionally deposited protein modifications. more...
