Figure 4From: Upregulation of the zebrafish Nogo-A homologue, Rtn4b, in retinal ganglion cells is functionally involved in axon regeneration Downregulation of Rtn4b in RGCs by MO1. After application of the control (Co) MO to the lesioned optic nerve, Rtn4b labeling of RGCs in retina whole mounts was intense at 5 days after ONS (A,B), but was markedly reduced when MO1 against Rtn4b (C,D) was offered. (B,D) The Rtn4b AB-labeled cells contain Lissamine (red) conjugated to the MOs. Examples of RGCs are outlined (white interrupted lines). DAPI stains the nuclei. Scale bar, 10 μm. (E) Western blot analysis showing a significant decrease in Rtn4b expression in retinae 5 days after ONS and application of MO1 and MO2 (P < 0.0001), respectively, to the optic nerve. Alpha-tubulin served as loading control.Back to article page
