Transient transfection of wild type and mutated CYP24 promoter linked to the firefly luciferase gene in human kidney cells (HEK-293). Calcitonin (CT) stimulates the CYP24 promoter activity some 4-fold in all constructs except those in which the GC and CCAAT sites have been mutated indicating that calcitonin acts on this gene through transcription factors that bind to these sites. Data are reproduced with permission, from reference 24. (Gao XH, Dwivedi PP, Omdahl JL, Morris HA, May BK. 2004 J Molec Endocrinol 32:87-98)
