| Outline of Final Research Achievements |
Inclusion Body Myositis is suggested to associate with endoplasmic reticulum stress. In this study, approximately 4000 compounds have been searched through the cell-based high-throughput assay we developed. We identified the compound which could activate the PERK signaling pathway. The identified compound was able to induce ATF4, which is biomarker of PERK signaling activation, in cultured cells but not in mice. This incompatibility could be due to poor drug delivery in vivo, as the compound had extremely poor solubility. Although it is necessary to improve the compound solubility through structural, the identified compound has a unique core structure compared with other known PERK signaling modifiers
