Cis elements in the FOXA1-binding regions of the SEMA3C locus. FOXA1 motif-containing regions of the SEMA3C promoter, second intron, and twelfth intron were cloned into the reporter vector, pGL3-Basic. LNCaP were co-transfected with reporter plasmids and either empty overexpression vector (‘pc’) or a FOXA1 overexpression plasmid (‘FOXA1’), stimulated with R1881 (5 nM), and then harvested to determine luciferase activity (a). Overexpression of FOXA1 was verified by Western blot. pGL3-S3Ci2 reporter construct was titrated against increasing amounts of FOXA1 overexpression plasmid (b). Western blot was used to monitor FOXA1 levels. Cloned regions are displayed and FOXA1 motifs (red) and AR elements (bold, underlined) are indicated (c). Minus strands are shown.
