| Outline of Final Research Achievements |
By using mouse strains that share the mutant coproporphyrinogen oxidase gene but have distinct genetic background, importance of endoplasmic reticulum stress response pathway and cell adhesion molecules (gap junction protein, alpha, periplakin, periplakin, and armadillo repeat gene deleted in velocardiofacial syndrome) to development and time of onset of cataracts was revealed.

| Academic Significance and Societal Importance of the Research Achievements |
高齢者の多くに認められ、生活の質を大きく低下させる一因となっているにもかかわらず未だ不明な点が多い加齢性白内障の発症機序・経路の一端として小胞体ストレス反応、および細胞間結合タンパク質を明らかとすることができた。これらの経路を標的とした加齢性白内障の治療・予防の開発に新たな方向性を示すことができた。
