Proteomic analysis of Pde6ɑD670G retina and vitreous at early-, mid-, and late-stage retinitis pigmentosa (RP). (a) Timeline of the clinical disease presentation in Pde6ɑD670G mice. (b) Histological analysis of Pde6ɑD670G mouse retinas at early-(P11), mid-(P30) and late-(P72) stage disease compared to a wild-type mouse at (P12) shows loss of the ONL photoreceptor cells over time. RPE, retinal pigment epithelium; ONL, outer nuclear layer; INL, inner nuclear layer; GCL, ganglion cell layer. Scale bar = 100 µm. (c) Protein spectral counts were analyzed by 1-way ANOVA followed by hierarchical clustering. A total of 1,384 proteins were differentially expressed in the Pde6ɑD670G vitreous and retina samples compared to controls (p < 0.05 [1-way ANOVA]). Results are represented as a heatmap and display protein expression levels on a logarithmic scale. Orange indicates high expression while dark green/black indicates low or no expression.
