GenomicsGenome-wide assay of Vezf1 and RNA Polymerase II binding
The protein Vezf1 plays multiple roles important for embryonic development. In Vezf1-/- mouse embryonic stem (MES) cells our earlier data showed widespread changes in gene expression profiles, including decreased expression of the full length active isoform of Dnmt3b methyltransferase and concomitan...

TranscriptomicsMapping of INS promoter interactions reveals its role in long-range regulation of SYT8 transcription
Insulin (INS) synthesis and secretion from pancreatic M-NM-2 cells are tightly regulated; their deregulation causes diabetes. Here we map INS-associated loci in human pancreatic islets by 4C and 3C techniques and show that the INS gene physically interacts with the SYT8 gene, located over 300 kb ...

GenomicsMediation of CTCF transcriptional insulation by DEAD-box RNA-binding protein p68 and steroid receptor RNA activator SRA
CCCTC-binding factor (CTCF) is a DNA-binding protein that plays important roles in chromatin organization, though the mechanism by which CTCF carries out these functions is not fully understood. Recent studies show that CTCF recruits the cohesin complex to insulator sites and that cohesin is require...

GenomicsChromatin architecture organized by histone variants H3.3 and H2A.Z in the human genome
To understand how chromatin structure is organized by different histone variants, we have measured the genome-wide distribution of nucleosome core particles (NCPs) containing the histone variants H3.3 and H2A.Z in human cells. We find that a special class of NCPs containing both variants is enriched...
