Research Abstract |
We revealed that zebrafish photoreceptor cell death model ovl shows photoreceptor cell death which relates phototransduction cascade. The cell death mechanism connects at transducine with phototransduction via adenylyl cyclase. Then we established RP zebrafish model which possesses human Q344X mutated rhodoposin. The mechanism of photoreceptor cell death was observed in this model and other mammalian RP model and will be a novel target of RP theraphy.
