Quantitative analysis of bi-modal binding of BET proteins at promoters predicts I-BET sensitivity
We identified a chromatin displacement signature for the bromodomain proteins BRD2, BRD3 and BRD4 at TSS following treatment with I-BET152, an inhibitor of BET proteins. By integrating ChIP-seq, RNA-seq and Chem-seq data, we correlated alteration of the BRD4 signature at TSS with strong downregulation of gene expression which will facilitate identification of markers of sensitivity and resistance to drug. Overall design: Examination of drug effect on chromatin bound proteins of sensitive and resitant cell lines
