TranscriptomicsArgonaute proteins couple chromatin silencing to alternative splicing (RNA IP-Seq)
While Argonaute (AGO) proteins play a major role in transcriptional gene silencing (TGS) in many organisms, their role in the nucleus of somatic mammalian cells remains elusive. Here, we have purified AGO1 and AGO2 chromatin-embedded complexes, and found these proteins associated with previously des...

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...

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...

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. ...
