The thickness of ONL decreased and the apoptosis of retinal cells increased in the EYS?/? zebrafish.
(A) Retinal histology analysis of WT and EYS?/? zebrafish. Retinal sections of EYS?/? zebrafish stained with hematoxylin/eosin (HE) at indicated ages. RPE, retinal pigment epithelium; OS, outer segment; IS, inner segment; ONL, outer nuclear layer; OPL, outer plexiform layer; INL, inner nuclear layer; IPL, inner plexiform layer; GCL, ganglion cell layer. Scale bars: 50??m. (B) TUNEL staining between WT and EYS?/? zebrafish. Scale bars: 50??m. (C) Comparison of the ONL thickness between WT and EYS?/? zebrafish at indicated ages (n?=?3). Quantitative analysis revealed a significant reduction of the ONL thickness at 3?mpf (P?=?0.0479), 4?mpf (P?=?0.0258), 8?mpf (P?=?0.0122), 16?mpf (P?=?0.0272) in the EYS?/? zebrafish. (D) Quantification of TUNEL positive cells in WT and EYS?/? zebrafish at indicated ages (n?=?3). Quantitative analysis revealed a significant increase of TUNEL positive cells at 8?mpf (P?=?0.0341), 16?mpf (P?=?0.0028) in the EYS?/? zebrafish.
