The mRNA level of EphA3 differs significantly (192‐fold) between androgen‐independent PCa and androgen‐dependent PCa cell lines according to a DNA methylation chip‐based study.7 Our previous data showing that the EphA3 gene is AR‐regulated and contains an AR genomic binding site was obtained using chromatin immunoprecipitation (ChIP) in combination with direct sequencing (ChIP‐seq). Here, AR is linked to posterior cortical atrophy.
