Abstract:
:N-methyl-N-nitrosourea (MNU) is widely used to study the mechanism of retinal degenerative diseases (RDs) because of its selectivity of photoreceptor cell death. Many reports suggest that excessive nitric oxide (NO) plays a crucial role in neuronal cell death. We hypothesized that nitric oxide synthase (NOS)/NO are involved in photoreceptor cell death by MNU. We found that the levels of NO increased after MNU treatment. Furthermore, we demonstrated that neuronal NOS specific inhibitor attenuated photoreceptor cell death by MNU in mice. We believe that our findings might be a new target for the treatment of RDs.
