RESUMO
@#To effectively screen treating pigmentation disorders drug, a new transgenic zebrafish drug screening model was constructed. Green fluorescent protein(GFP)were drived by tyrosinase-related protein 1a (tyrp1a)promoter specific expression in melanocyte. Effect of N-Phenylthiourea(PTU)and alpha-melanaocyte stimulating hormone(α-MSH)on the GFP expression and melanogenic of tyrp1a: eGFP zebrafish were photographed under the steromicroscope. Results showed that PTU could significantly inhibit the melanogenic and expression of GFP of zebrafish. As compared with control group, α-MSH treatment resulted in marked stimulation of body pigmentation and expression of GFP. In conclusion, a new transgenic zebrafish drug screening model was successfully established, which can be used for treating pigmentation disorders.
