| Caption | Effect of genetic depletion of 11-cis-retinal production on retinal degeneration. A, whole retinal images obtained from postnatal day (PND) 36 Rhotm1.1Kpal/Rho+ (P23H/+) and Rhotm1.1Kpal/Rho+ Lrattm1Kpal/Lrattm1Kpal (P23H/+ Lrat-/-) littermate mice. Plastic sections were made from dorsal-ventral axis cut and stained with toluidine blue. Both mice were heterozygous with respect to the L450M variation of RPE65 (RPE65450L/450M). The outer nuclear layer (ONL), observed as a purple line in the P23H/+ mouse retina (left panel), was almost gone and only retained near the cilial marginal zone (CMZ) in the P23H/+ Lrat-/- mouse (right panel; indicated by curved line). B, high magnification retinal images shown in A and Rhotm1.1Kpal/Rho+ Lrattm1Kpal/Lrattm1Kpal mice at PND 28-30. Images were taken from the midpoint between optic nerve (ON) and CMZ. Genetic deletion of 11-cis-retinal production promoted retinal degeneration in the P23H/+ mouse at PND 36 but not in Rho+/- Lrat-/- mouse at PND 28-30. In the P23H/+ Lrat-/- mouse, however, the ROS were almost undetectable, and the number of photoreceptor nuclei was dramatically reduced compared with a littermate that had 11-cis-retinal (P23H/+). | ||||||||||
