TranscriptomicsChromatin modifications induced by PML-RARalpha repress critical targets in leukemogenesis as analyzed by ChIP-Chip.
A global view of PML-RAR? transcriptional functions was obtained by genome-wide binding and chromatin modification analyses, combined with genome wide expression data. Complete Abstract: The translocation t(15;17) generates the chimeric PML-RAR? transcription factor that is the initiating event of ...

GenomicsH3K36ac is an evolutionary conserved histone modification that marks active genes in plants
In eukaryotic cells, DNA is tightly packed in the nucleus in chromatin which has histones as its main protein component. Histones are subject to a large number of distinct post-translational modifications, whose sequential or combinatorial action affects genome function. Here, we report the identifi...

GenomicsCharacterization of genome-wide enhancer-promoter interactions reveals co-expression of interacting genes and modes of higher order chromatin organization
Recent epigenomic studies have predicted thousands of potential enhancers in the human genome. However, there has not been systematic characterization of target promoters for these potential enhancers. Using H3K4me2 as a mark for active enhancers, we identified genome-wide enhancer-promoter interact...

GenomicsChromatin modification by SUMO-1 stimulates the promoters of translation machinery genes
We determined the occupancy of SUMO-1 on chromatin in HeLa cells by use of chromatin affinity purification coupled with next generation sequencing 18 samples examined in syncrhonized HeLa cells: Cells in G1, early S (S0)/mid (S3)/ late S phase (S6), and mitosis (M), triplicates for each sample. 1 Ch...

GenomicsEpigenetic Repogramming by an Environmental Carcinogen Through Chromatin Domain Disruption [ChIP-Seq]
Alterations in chromatin modifications, including DNA methylation and histone modification patterns, have been characterized under exposure of several environmental pollutants, including nickel. As with other carcinogenic metals, the mutagenic potential of nickel compounds is low and is not well cor...

ProteomicsA quantitative proteomic analysis of in vitro assembled chromatin
The structure of chromatin is critical for many aspects of cellular physiology and is considered to be the primary medium to store epigenetic information. It is defined by the histone molecules that constitute the nucleosome, the positioning of the nucleosomes along the DNA and the non-histone prote...

GenomicsProfiling Genome-wide Chromatin Methylation with Engineered Posttranslation Apparatus within Living Cells
We have engineered the chromatin-modifying apparatus and formulated a novel technology, termed Clickable Chromatin Enrichment with parallel DNA sequencing (CliEn-seq), to probe genome-wide chromatin modification within living cells. Examine (E)-hex-2-en-5-ynylation mediated by engineered G9a Y1154A ...

ProteomicsThe kinase NEK6 positively regulates LSD1 activity and accumulation in local chromatin sub-compartments (CSCs)
LSD1 is involved in multiple essential roles in mammalian biology and various modes of LSD1 regulation are described ranging from interaction with specific coregulators to distinct post translational modifications. Here we show that NEK6 positively influences LSD1 activity and we observe a strong c...

ProteomicsHuman chromatin platforms for the study of transcription and RNA regulation
Here we describe tools to study the step-wise assembly of protein complexes on chromatin in a highly-controlled manner using reconstituted chromatin platforms and quantitative proteomic profiling. We profile the early steps in transcriptional activation and highlight the potential for understanding...
