MITF ChIP-seq Peaks identified in GIST-T1 and GIST48 (SI1: Table S2) were intersected with ETV1 (GSM2527316) and HAND1 (GSM2527318) ChIP-seq datasets and H3K27ac ChIP-seq peaks (GSM2527250 and GSM2527252) to evaluate MITF binding at active regulatory regions. This evidence concerns the gene MITF and gastrointestinal stromal tumor.
