英文摘要
The present study aimed to elucidate the pathological mechanism in light induced retinal damage using 8-oxoguanine-DNA glycosylase (OGG1), human MutT Homolog 1 (MTH1) and MutY glycosylase homologue (MUTYH) knockout mice. Mice were exposed to 350-385 nm wavelengths light, and retinal radiant exposure was 75 J/cm2. Retinal light damage was reduced in MUTYH knockout mice, indicating that MUTYH involved in the pathological mechanism of light damage. Our results show the possibility that the suppression of neurodegeneration by control of MUTYH may effectively protect retinal light damage.
