Drier et al. describe positive feedback loop generated by enhancer hijacking that drives adenoid cystic carcinoma

Drier et al. describe how enhancer hijacking rewires the regulation of the oncogenic transcription factor MYB and drives adenoid cystic carcinoma. Translocation of MYB near super-enhancers that are themselves bound by MYB creates a vicious cycle where MYB drives its own transcription. MYB also binds enhancers that drive different regulatory programs in alternate cell lineages in … Continued

Flavahan, Drier et al., characterize insulator dysfunction in glioma

Will Flavahan, Yotam Drier, et al. demonstrate that hypermethylation-induced loss of genomic insulator function causes the development of oncogenic genome topology configurations in IDH1-mutant glioma. This topological restructuring allows a constitutive housekeeping enhancer to interact with and drive the potent glioma oncogene PDGFRA. Key Findings: -The hypermethylator phenotype observed in IDH1-mutant glioma extends to CpGs … Continued

Quantitative multiplex ChIP-seq is here

van Galen et al. introduce Mint-ChIP, an approach for multiplexed ChIP-seq on small cell numbers. The approach allows quantitative comparisons of global and locus-specific histone modification levels. The technology is demonstrated by mapping hematopoietic stem cell chromatin landscapes and quantifying changes in leukemia cells treated with epigenetic inhibitors. Detailed protocol now available on the Resources page. … Continued

Ryan, Drier et al. link enhancers to oncogene activation in B cell lymphoma

Russell Ryan and Yotam Drier describe PEAR-ChIP, a novel approach for the detection of genomic rearrangements associated with acetylated chromatin. The authors apply this technology to patient samples from several distinct subtypes of B cell lymphoma, revealing therapeutically targetable rearrangements, and uncovering novel mechanisms by which the oncogenes MYC and BCL6 are regulated via native … Continued
