| Outline of Final Research Achievements |
PIWI proteins, germline-specific members of the Argonaute family, function in RNA silencing in the gonad by associating specifically with PIWI-interacting RNAs (piRNAs). We found that it is possible to generate piRNAs that were artificially designed, using drosophila ovarian somatic cells. In this research, we developed the novel gene knockdown method using artificial piRNAs. We constructed the piRNA expression vectors that produces artificial piRNAs targeting optional genes, and examined the silencing effect by artificial piRNAs. As a result, artificial piRNAs succeeded in silencing of the endogenous gene, and we found that this suppression was occured at the transcriptional level by piRNA pathway.
