Annexin a7 Immunohistochemistry (downregulated on gene array at P90). (A) Retinal cross sections from Pde6b^rd1/rd1 and Pde6b^wt/wt mice stained for DAPI (blue), CHX10 (green) and annexin a7 (red). ONL – Outer nuclear layer, OPL – Outer Plexiform layer, INL- Inner nuclear layer, IPL –inner plexiform layer, GCL – Ganglion cell layer. Scale bar = 20 μm. White box indicates area from which close up images in panels B & D are taken. (B&D) Close up images of bipolar cell bodies in Pde6b^rd1/rd1 retinae (B) and Pde6b^wt/wt (D) at four time points during degeneration (P40, P90, P120, P150). CHX10 (green) and annexin a7 (red). Scale bars = 5 μm. (C) Colocalised pixels above threshold - a semiquantitative index of protein staining. Normalised to highest value over all retinae stained for annexin a7. Dots represent the mean value for each animal, lines connect the means for each group at that timepoint. Star markers on graph represent adjusted p values, Sidak's method for multiple comparison (i.e. None reaching significance, see results section for details). red line = Pde6b^rd1/rd1; blue line = Pde6b^wt/wt.
