| Outline of Final Research Achievements |
Our purpose of this study was the involvement of epigenome in glaucoma pathology, and drug discovery by identifying new targets. The HDAC inhibitor vorinostat was evaluated for the conventional outflow, and it was revealed that it significantly suppressed the increase in outflow resistance induced by TGF-β2. In addition, the effect of conjunctival scarring on the prognosis of glaucoma filtration surgery was evaluated using conjunctival fibroblasts. Both vorinostat and decitabine were found to have the effect of suppressing the transformation of conjunctival fibroblasts into myofibroblasts by TGF-β2. These results indicate that epigenetic drugs may be effective in treating glaucoma.

| Academic Significance and Societal Importance of the Research Achievements |
本研究によって、緑内障進行に影響を与える眼圧調節に対してエピゲノムの関与が示され、眼圧下降剤としてのHDAC阻害剤の可能性も示された。また、緑内障濾過手術後の眼圧調節において濾過胞の維持が重要であるが、エピジェネティクス薬が瘢痕化を抑制する可能性を示したことから術後予後を改善する治療薬としての可能性も考えられる。
