Figure 7. Kif5a overexpression exacerbates retinal ganglion cell (RGC) death.

Figure 7.

(a) Optic nerves were collected 2 weeks after intravitreal injection of adeno-associated virus (AAV)-Kif5a-FLAG. Immunoprecipitation showed the presence of FLAG-tagged protein at the molecular weight of Kif5a. Co-immunoprecipitation of β-III tubulin confirmed that overexpressed Kif5a transported to the optic nerve and bound to the cytoskeleton. (b) RGC survival was not affected 4 weeks after viral injection of Kif5a compared to a control GFP virus (control n = 6, OE n = 7). Two-tailed, two-sample, t-test. (c) Representative example of wholemount retinas stained with RBPMS, an RGC-specific marker, 2 weeks after optic nerve crush, injected with either AAV-GFP or AAV-Kif5a-FLAG 2 weeks before crush. Scale bar, 100 µm. (d) Quantification of RBPMS + cell density after optic nerve crush (ONC) across entire retinal surface. Each point represents one retina (control n = 7, OE n = 8). Two-sample, two-tailed t-tests, p < 0.0001.
