(+1.1kb-2.5kb) and AR promoter fragments (0.4–0.8kb,
0.8–1.2kb, 1.2–1.6kb, 1.6–1.8kb, 1.8–2.3kb) were
amplified by PCR from LNCaP genomic DNA. The AR promoter P1, P2 and full
length were inserted into pGL4.10 vector (catalog number E6651; Promega) by
using XhoI and HindIII sites and AR fragments were cloned into the
pRetroX-Tight-Pur-Luc plasmid (Clontech laboratories, Inc.) by using BamHI
and BglII. All plasmids were verified by sequencing.
