Among the eight prostate cancer cell lines in the dataset (22Rv1, DU145, LNCaP, MDA-PCa-2B, NCI-H660, PrECLH, PC3, and VCaP), FOXA1 mRNA abundance is above the 90th percentile in all but one cell line (PrECLH) compared with the >56,000 protein coding and non-protein coding genes profiled (Supplementary Fig. 2b). This evidence concerns the gene FOXA1 and prostate cancer.
