Fig. 11 Pharmacological inhibition of PrkC activity reduces cilia length and causes opsin mislocalization. (A–C) Transverse cryosections of 4 dpf retinas were stained with phalloidin to label actin (red) and 1D1 to label rhodopsin (green). (D–F) Immunohistochemistry on cryosections to label Ift88 in cilia (red) and acetylated tubulin to label ciliary microtubules (green). Arrows identify cilia. Sections were also counterstained with DAPI (blue). (G) Quantification of cilia length. Cilia length in 4 dpf wild-type photoreceptors (43.2 microns) and the non-myristoylated control inhibitor (48.9 µm) were not statistically different from each other, but both were statistically different from larvae treated with the PrkC inhibitor (27.1 microns). Error bars show standard deviation. (***p≤0.0001) Scale bar = 10 μm.
