GenomicsEpstein-Barr Virus Exploits Intrinsic B-Lymphocyte Transcription Programs to Achieve Immortal Cell Growth
Epstein-Barr Virus Nuclear Antigen 2 (EBNA2) gene regulation through the cell RBPJ transcription factor (TF) is essential for conversion of resting B-lymphocytes (RBLs) into Lymphoblastoid Cell Lines (LCLs). ChIP-seq investigation of EBNA2 and RBPJ sites in LCL DNA found EBNA2 at 5151 and RBPJ at 10...

GenomicsGC-rich Sequence Elements Recruit Polycomb Repressive Complex 2 (PRC2) in ES cells
Polycomb proteins are epigenetic regulators that localize to developmental loci in the early embryo where they mediate lineage-specific gene repression. In Drosophila, these repressors are recruited to sequence elements by DNA binding proteins associated with Polycomb repressive complex 2 (PRC2). Ho...

GenomicsGenome-wide Chromatin Maps Derived from Limited Numbers of Hematopoietic Progenitors
Whole genome mapping of protein-DNA interactions can be performed by coupling chromatin immunoprecipitation (ChIP) with high-throughput sequencing (ChIP-Seq). However, current methods require large amounts of starting materials which precludes their application to rare cell types. Here, we combine a...

GenomicsChromatin Profiling by Directly Sequencing Small Quantities of Immunoprecipitated DNA
Chromatin structure and transcription factor localization can be assayed genome-wide by sequencing genomic DNA fractionated by protein occupancy or other properties. However, current technologies involve multiple steps that introduce bias and inefficiency. Here we apply a single-molecule approach to...

GenomicsJarid2 and PRC2, Partner in Regulating Gene Expression
The Polycomb Group proteins foster gene repression profiles required for proper development and unimpaired adulthood, and comprise the components of the PRC2 complex including the histone H3 lysine 27 (H3K27) methyltransferase Ezh2. How mammalian PRC2 accesses chromatin is unclear. We find that Jari...

GenomicsCombinatorial patterning of chromatin regulators uncovered by genome-wide location analysis in human cells
Hundreds of Chromatin Regulators (CRs) control chromatin structure and function by catalyzing and binding histone modifications, yet the rules governing these key processes remain obscure. Here, we present a systematic approach to infer CR function. We developed ChIP-string, a meso-scale assay that ...

GenomicsGenome-wide chromatin maps of T-cell acute lymphoblastic leukemia (T-ALL) [ChIP-seq]
Here we modeled T-ALL resistance to Notch inhibition, identifying M-bM-^@M-^XpersisterM-bM-^@M-^Y cells that readily expand in the presence of gamma secretase inhibitor (GSI) and the absence of Notch signaling. Rare persister cells are already present in naM-CM-/ve T-ALL populations, and the reversi...

GenomicEpigenetic and Genetic Profiling in Lymphoma

Lymphomas are a prevalent and heterogeneous family of cancers arising in cells of the immune system. Drivers of lymphomagenesis include genomic rearrangements that juxtapose active regulatory elements with specific oncogene targets, as well as mutations affecting specific transcription factors an...

GenomicsGenome-wide maps of chromatin state in pluripotent and lineage-committed cells
Genome-wide maps of chromatin state (H3K4me3, H3K9me3, H3K27me3, H3K36me3, H4K20me3) in pluripotent and lineage-committed cells We report the application of single-molecule-based sequencing technology for high-throughput profiling of histone modifications in mammalian cells. By obtaining over four b...
