A reduction of the H2O2 levels impairs the RGC projections. (A, B) HyPer imaging at 2 dpf in the control (n=3), or Nox-i-treated larvae (n=3). (C) Number of pixels corresponding to the pseudo-colour (HyPer ratio). (D-K) RGC arborization at 3 dpf in control embryos (D, G), embryos treated with Nox-i (E, H), Nox-i+H2O2 (I) or H2O2 (J) from 2 to 3 dpf. (D, E) GFP expression in the [pou4f3:GAL4, UAS:GAP-GFP] larvae with or without Nox-i treatment. (F) Branch number per axon in this transgenic line. (G-J) DiO RGC labelling at 3 dpf. The maximum length of the projections was quantified (K). The n values are indicated at the bottom of each column of the graph. Representative images are shown. The error bars represent the standard error of the mean (SEM) (*p<0.05; ***p<0.001). |
