Fig. 6 Effects of deiodinase KD on relative rod and cone photoreceptor number. (A-L) Immunohistochemical stainings with Zpr3, Zpr1, anti-blue opsin and anti-UV opsin antibodies on cryosections of the eye of control (A,D,G,J), D1D2MO (B,E,H,K) and D3bMO (C,F,I,L) larvae at 3 dpf. Zpr1 is a marker for both green and red cone photoreceptors, Zpr3 is a marker for rod photoreceptors and anti-blue and anti-UV opsin label the outer segment of blue and UV cone photoreceptors respectively. Blue: DAPI staining of the nuclei; Green: Zpr1/Zpr3+Alexa488 or anti-blue/anti-UV + FITC. (M-P) Data for relative rod/cone number (expressed per retinal surface area) are shown as mean + SEM (n ≥ 5 per group). Groups with no common letter are significantly different (p < 0.05). Data in (N,O,P) followed Gaussian distribution and were analyzed by one-way ANOVA with Tukey post hoc test. Data in (M) did not assume Gaussian distribution and were analyzed by Kruskal-Wallis and Dunn′s post hoc test. SCMO: control group, D1D2MO: KD of D1+D2; D3bMO: KD of D3b.
