Figure Legend Snippet: ( A ) Sequence of the human hepcidin promoter (acc. no. AD000684.1) with two putative HIF binding motifs which also conform to E-box/USF binding sites (yellow boxes, red letters) and one additional HIF binding site (yellow); binding sites for p53 (light blue), AP1 (blue-green), C/EBPα (green), STAT3 (pink), SMAD (grey) are also marked; mRNA sequence (bold), translation start codon (ATG); underlined sequence represents region highly conserved between human and murine hepcidin 1 gene. Lower sequence, two putative HREs were identified in the mouse hepcidin 1 gene about 2.1 kbp upstream to the transcription start. These HIF binding sites do not conform to E-box/USF binding site consensus sequence. ( B ) A 617-bp human hepcidin promoter construct (HAMP.prom) responded differently to hypoxia (hyp), DMOG and DP in HepG2 and Huh7 cells after 16 h of stimulation (co = control). Data are means±SD of five (HepG2 cells) or three (Huh7 cells) independent experiments. ( C ) SiRNA knock-down of HIF-1α (1α) or HIF-2α (2α) did not reverse the down-regulation of promoter activity by DMOG in Huh7 cells; a 6xHRE luciferase reporter served as control. 3 luc siRNAs served as negative control for the pGL2-based hepcidin promoter constructs and 2 luc siRNA as negative control for the pGL3 6xHRE; deletion of the putative HREs in the HAMP promoter (HAMP.promΔHRE) did not alter the response of the luciferase construct to DMOG nor did HIF-α knock-down. ( D ) Deletion of putative HREs (HAMP.promΔHRE) did not alter the response of the hepcidin promoter to DMOG, DP or hypoxia in Huh7 cells. ( E ) Overexpression of a stable HIF-1α triple mutant (HIF-1αTM) tended to increase hepcidin promoter activity in comparison with the empty vector control (pcDNA3). The 6xHRE reporter served as positive and the promoter-less pGL2basic vector as negative control, respectively; HAMP promoter activities given in B–D are means of three independent experiments±SD. * p <0.05; ** p <0.01 vs. unstimulated control (co).
