C4-2 cell lines were treated with 10nM of DHT for 4 hours, followed by ChIP-Seq analyses as previously described (45 (link)). Briefly, chromatin immunoprecipitation was carried out using anti-AR antibody (Santa Cruz, Sc-816x), followed by qPCR analysis using the SYBR Green method on the QuantStudio 3 Real-time PCR system (Thermo Fisher Scientific). The primers were listed below: PSA-Enhancer (ARE3): Forward, 5′-GCCTGGATCTGAGAGAGATATCATC-3′; Reverse, 5′-ACACCTTTTTTTTTCTGGATTGTTG-3′; TMPRSS2-Enhancer (−14kb): Forward, 5′-TGGTCCTGGATGATAAAAAAAGTTT-3′; Reverse, 5′-GACATACGCCCCACAACAGA-3′.
