GenomicsH3K4 tri-methylation provides an epigenetic signature of active enhancers
Combinations of post-translational histone modifications shape the chromatin landscape during cell development in eukaryotes. However, little is known about the modifications exactly delineating functionally engaged regulatory elements. For example, although histone H3 lysine 4 mono-methylation (H3K...

GenomicsEffect of Ets1 knockdown in the P5424 thymic cell line
We performed ChIP-Seq for Ets1 and histone modifications in P5424 thymic cells, without and with Ets1 knockdown via shRNA. Overall, we find that loss of Ets1 results in specific, higher occupancy of H3K4me1-marked nucleosomes at the Ets1 binding site, but not H3K4me3 nucleosomes. We verified the spe...

TranscriptomicsTranscription Initiation Platforms and GTF recruitment at tissue-specific enhancers and promoters
Recent works have shown that RNA Polymerase (Pol) II can be recruited to, and transcribe, distal regulatory regions. Here, we analyzed transcription initiation and elongation through genome-wide localization of Pol II, General Transcription Factors (GTFs) and active chromatin in developing T-cells. ...

TranscriptomicsGene expression analysis of Ets1-/- CD4+ CD8+ thymocytes
We performed ChIP-Seq for hallmark TFs (Ets1, Runx1), histone modification marks (H3K4me1, H3K4me2, H3K4me3, H3K27me3, H3K36me3), total RNA Pol II, short RNA-Seq as well as nucleosome mapping mainly in murine Rag2 -/- thymocytes. We also performed ChIP-Seq for E47 as well as nucleosome mapping, gene...

GenomicsCapStarr-seq: a high-throughput method for quantitative assessment of enhancer activity in mammals (ChIP-Seq)
Here we developed CapStarr-Seq, a novel high-throughput strategy to quantitatively assess enhancer activity in mammals. This approach couples capture of regions of interest to previously developed Starr-seq technique. Extensive assessment of CapStarr-seq demonstrated accurate quantification of enhan...

TranscriptomicsLong-range bidirectional transcription is a general feature of developmental gene promoters in mammals (RNA-Seq 1)
Recent studies have revealed a myriad of non-coding transcripts in different organisms. For instances, the presence of short bidirectional transcripts is a hallmark of active promoters in mammals, while upstream non-coding transcripts can be detected at most expressed genes in conditions where the R...
