Interestingly, the published ChIP-seq datasets on ETV1 and ETV4 chromatin binding in PCa cells [15, 24] indicate a possible ETV1 binding site in the 3′ untranslated region of GUCY1A1 locus (no ETV1 binding was found on GUCY1B1 gene locus) (Supplementary Figure S4A). Here, ETV4 is linked to posterior cortical atrophy.
