| Outline of Final Research Achievements |
We indentified a main dpf1 transcrypt, dpf1-002, in the zebrafish central nervous system and determined the nucleotide sequence and expression pattern in embryos. In addition, in the dpf1-tTA-GFP fish, the GFP transgene was transcrived from the start point different from that of dpf1-002, and the expression of endogenous dpf1-002 was not affected by the expression of the transgene. We intend functional inhibition using morpholino antisense oligonucleotides (MO) for dpf1-002, but unfortunately have not yet observed clear-cut developmental nerve defects in the injected embyros. Examination such as the coinjection of different MOs is necessary. The different gene targeting approach such ad genome editing may also be needed in future.
