Suppression of arl13b and PCP components result in shortened photoreceptor cilia and outer segments. (A-D) Immunohistochemistry using antibodies against acetylated α-tubulin (red) to label cilia in retinal cryosections of 5 dpf zebrafish larvae. (E-H) Immunohistochemistry using rhodopsin antibodies to label photoreceptor outer segments in retinal cryosections of 5 dpf larvae. (I) Quantification of cilia length. (J) Quantification of outer segment area. All sections were counterstained with DAPI. Results are significant (****P < 0.0001) using a 1-way ANOVA with Tukey′s multiple comparisons test correction. Error bars: ± SEM. Scale bar: 10 µm.
