| Outline of Final Research Achievements |
Although RNAs are known to undergo various modifications, the physiological role of RNA modifications remains unknown. Since autoantibodies that bind to ncRNAs have been found in patients with autoimmune diseases, we speculate that RNA modification could be the marker for self-recognition. To investigate such possibility, we generated artificial anti-RNA antibodies that specifically bind to modified RNA molecules and developed zebrafish with loss of RNA modifications. We found that the RNA modification is essential for zebrafish development and dynamically regulates the expression of many relevant genes.
