PURPOSE The effects of aging and light exposure on cone photoreceptor survival were compared between mouse retinas of neural retina leucine zipper knockout (Nrl(-/-)) mice and double-knockout mice lacking G-protein-coupled receptor kinase 1 (Nrl(-/-)Grk1(-/-)). METHODS Mice were reared in total darkness, ambient cyclic light, or constant light, and their(More)
Recent gene expression studies on mouse models for retinal degeneration identified deregulation of Pituitary tumor transforming gene 1 (Pttg1) as a potential susceptibility factor involved in photoreceptor cell death. Pttg1 is a transcription regulatory protein involved in sister chromatid segregation, and Pttg1 −/− mice exhibit testicular and splenic(More)
