Identification of in vivo ARBSs in LNCaP cells on the encyclopedia of DNA elements (ENCODE) array by ChIP-chip analysis. (a) An expanded view of the UGT1A locus on the ENCODE region ENr131 from chromosome 2q37 is shown in its genuine 5′−3′ orientation. ARBS no. 1 is located on the 5′ upstream region of UGT1A1, or on intron 1 of other UGT1A isoforms. (b) An expanded view of the CDH2 on the ENCODE region ENr213 from chromosome 18q11.2 is shown in its genuine 3′–5′ orientation. ARBS no. 10 is located on intron 1 of CDH2.
