For this study, we selected tracks available for H3K4me1/H3K27ac, ATAC-seq, and FOXA1 on pancreatic and prostate cell types, which include several PDAC cell lines like CFPAC1, PT45-P1, BxPC-3, and PANC-1, and prostate cancer cell lines like LnCAP, where the control of ABCC4 transcription by FOXA1/GATA2 binding at intron one sites was first documented (Wu et al., 2014). Here, FOXA1 is linked to prostate cancer.
