Abstract:

The research was designed to study the activity and the structure of MITF promoter and to provide clues for studying this gene's regulation mechanism in hair follicle. Dual-luciferase expression vectors were constructed and transfected to DF1 cells with lip2000. The dual-luciferase detection kit was used to measure the relative luciferase activity. The 6 expression vectors with different promoter regions of MITF gene and 4 mutant vectors of the core promoter region were constructed in Bashang Long-tail chicken. The core promoter region from -660 bp to +200 bp was identified in chicken MITF gene. The function of -579 bp, -505 bp, -274 bp, -220 bp, -203--202 bp, -98 bp, -46 bp, -14 bp, +1 bp and +28 bp sites in regulating promoter activity was critical. The similarities of transcription factor binding sites including HOX family (HOXA3, HOXD8, HOXD9, HOXD10 and HOX11), NF-1, DBP, TFⅡD and TFⅡB to MITF were changed predicted by software.
