Outline of Final Research Achievements

We examined superoxide-producing capabilities in the cochlea and the retina from the age of 14 days after birth to 1-year-old. It was maximum from 2-month-old to 6-month-old, and then reached the plateau (from 6-month-old to 12-month-old). Moreover, it was enhanced/increased by aging and cisplatin, which is a famous anti-cancer drug exhibiting toxicity to hearing and vision. We also found that aging and cisplatin cause loss of outer hair cells in the cochlea and optic ganglion cells in the retina. These new findings suggest that diseases caused by superoxide may most frequently occur in the middle ages in humans.

Academic Significance and Societal Importance of the Research Achievements

感覚疾患は、近年増加傾向であり、この増加は今後も続くことが予測されている。しかしながら、有効な治療法が存在しない疾患が多いのが現状であり、その病因解明及び治療法開発が求められている。。本研究は、活性酸素によって起こることが示唆されている疾患(特に、視聴覚疾患)の発症時期及び発症機序の解明に大きなブレークスルーを起こす可能性があり、更には、原因不明の視聴覚疾患の新規治療法開発に繋がって行くものである。
