CHROMATIN ACTIVATION PROFILING OF STEREOTYPED CHRONIC LYMPHOCYTIC LEUKEMIAS

We used chromatin-immunoprecipitation followed by sequencing (ChIP-Seq) with an antibody for the H3K27ac (a bona fide histone mark for regulatory element activation) in sorted CLL cells from 46 CLL, including 21 cases from stereotyped subsets #1, #2, #4, and #8, and 15 normal B cell subpopulations. To understand their functional impact, we integrated our data with 16 RNA-seq data.
