Subtype-specific regulatory network rewiring in acute myeloid leukemia [DNase-Hypersensitivity]

Acute myeloid leukemia is a heterogeneous disease which is subdivided into different categories defined by disease-causing mutations in transcription factors, epigenetic regulators and signalling molecules. How different mutant regulators establish AML-specific transcriptional networks is unclear. Here we performed a comprehensive analysis of mutation-specific sets of cis-regulatory elements driving gene expression in AML blast cells from a carefully selected group of patients with alterations in genes encoding transcription factors (RUNX1, CEBPA) and signalling molecules (FTL3-ITD, RAS, NPM1). We show that each mutant regulator establishes a specific transcriptional and signalling network unrelated to normal cells driving the expression of unique sets of genes required for AML survival. Overall design: DNAse1-seq expreiments have been used to study the chromatin landscape of AML with different mutations
