Outline of Final Research Achievements |
In the upstream of the zebrafish murf1 gene, we identified the promoter region of zebrafish murf1 gene. With microinjection of the DNA construct including the promoter region and EGFP cDNA to zebrafish eggs, we successfully made the transgenic zebrafish (murf1:EGFP) line. RT-PCR confirmed that the murf1 expression corresponded with EGFP expression in the transgenic fish line. In the adult transgenic fish, murf1 corresponding with EGFP were predominantly expressed in skeletal muscle and heart. The transgenic zebrafish line might be excellent tool to evaluate the expression of murf1 under muscle atrophy. Using this transgenic fish, ten drugs were identified that can change murf1-expression from a chemical library. Our findings would be led to good tools and key molecules for treatment of muscle atrophy.
