GenomicsGenome-wide mapping of HATs and HDACs in human CD4+ T cells
Histone acetyltransferases (HATs) and deacetylases (HDACs) function antagonistically to control histone acetylation. As acetylation is a histone mark for active transcription, HATs have been associated with active and HDACs with inactive genes. We describe here genome-wide mapping of HATs and HDACs ...

GenomicsNOTCH1/RBPJ complexes drive target gene expression through dynamic interactions with super-enhancers
The main oncogenic driver in T-lymphoblastic leukemia (T-LL) is NOTCH1, which activates genes by forming chromatin-associated Notch transcription complexes. Gamma-secretase (GSI) inhibitor treatment prevents NOTCH1 nuclear localization, but most genes with NOTCH1 binding sites are insensitive to GSI...

TranscriptomicsHistone methylations and gene expression in naïve, central (TCM) and effector (TEM) memory CD8 T cells.
Histone methylations play a major role in regulating the chromatin state and gene expression, yet little is known about their involvement in differential gene expression and function of memory CD8 T cells. Here, we report a genome-wide analysis of two histone H3 methylations (H3K4me3 and H3K27me3) ...

TranscriptomicsDiscovery of biomarkers predictive of GSI response in triple negative breast cancer and adenoid cystic carcinoma
Next generation sequencing was used to identify Notch mutations in a large collection of diverse solid tumors. NOTCH1 and NOTCH2 rearrangements leading to constitutive receptor activation were confined to triple negative breast cancers (TNBC, 6 of 66 tumors). TNBC cell lines with NOTCH1 rearrangemen...

GenomicsModeling transcriptional cis-regulation with a library of genome-wide histone H3K27ac profiles
We describe, MARGE, Model-based Analysis of the Regulation of Gene Expression, a robust methodology that leverages a large library of genome-wide H3K27ac ChIP-seq profiles to predict key regulated genes and cis-regulatory regions in human or mouse. MARGE adopts a gene centric approach to define a re...

GenomicsPTIP promotes chromatin changes critical for immunoglobulin class switch recombination
Programmed genetic rearrangements in lymphocytes require transcription at antigen receptor genes to promote accessibility for initiating double-strand break (DSB) formation critical for DNA recombination and repair. Here we show that activated B cells deficient in the PTIP component of the MLL3 (mix...
