Title Linking aberrant chromatin features in chronic lymphocytic leukemia to deregulated transcription factor networks
Organism Homo sapiens
Experiment type Expression profiling by high throughput sequencing
Genome binding/occupancy profiling by high throughput sequencing
Methylation profiling by high throughput sequencing
Summary In chronic lymphocytic leukemia (CLL) a diverse set of genetic mutations is embedded in a deregulated epigenetic landscape that drives cancerogenesis. To elucidate the role of aberrant chromatin features, we mapped DNA methylation, 7 histone modifications, nucleosome positions, chromatin accessibility, binding of EBF1 and CTCF as well as the transcriptome of B cells from CLL patients and healthy donors. A globally increased histone deacetylase activity was detected and half of the genome comprised transcriptionally downregulated partially DNA methylated domains demarcated by CTCF. CLL samples displayed a H3K4me3 redistribution and nucleosome gain at promoters as well as changes of enhancer activity and enhancer linkage to target genes. A DNA binding motif analysis identified transcription factors that gained or lost binding in CLL at sites with aberrant chromatin features. These findings were integrated into a gene regulatory enhancer containing network enriched for B cell receptor signaling pathway components. Our study predicts novel molecular links to targets of CLL therapies and provides a valuable resource for further studies on the epigenetic contribution to the disease.

Mol Syst Biol 15, e8339. doi: 10.15252/msb.20188339
Overall design We analyzed a carefully selected cohort of clinically and genetically fully characterized primary leukemia cells in bulk samples and at the single cell level for genome-wide DNA-methylation, nucleosome position, DNA-accessibility by ATAC-seq, the 7 most relevant histone modifications plus CTCF and EBF1 by ChIPseq as well as the transcriptome. Raw sequencing data for all the samples are available at the European Genome-phenome Archive (, under the accession number EGAS00001002518.
