“…After cells were stimulated for 10 min with db-cAMP, extracts were prepared and processed for ChIP with the same antibody to phosphorylated CREB. We screened by PCR several genes, whose proximal promoter regions associate with phosphorylated CREB, and investigated murine prepronociceptin gene (Zaveri, Waleh, & Toll, 2006). The proximal promoter of murine prepronociceptin gene has one functional CRE site in a different location from the human promoter (Zaveri, Green, Polgar, Huynh, & Toll, 2002;Zaveri et al, 2006).…”
