ERF and posterior cortical atrophy: In order to mechanistically define how CIC and ERF (two TFs with known repressor function) were interacting to functionally regulate PCa, we performed chromatin immunoprecipitation followed by sequencing (ChIP-Seq) using a validated CIC antibody (Lin et al., 2020; Okimoto et al., 2019; Okimoto et al., 2017) in PNT2, and compared this to a publicly available ERF ChIP-Seq dataset in VCaP PCa cells (Bose et al., 2017), we were unsuccessful at pulling down ERF in PNT2 cells.
