AR and Familial prostate cancer: Based on normalized read densities, we categorized ChIP-seq peaks of prostate cancer oncogenic transcription factors (AR, ERG, and FOXA1) and transcriptional cofactors (SMARCA4, p300, and BRD4) at non-promoter regions into quartiles (Q1-Q4, where Q4 represents the top quartile and Q1 the bottom quartile).
