Functional evaluation of SIX6 variants on the volume of the optic nerve.

Representative whole mount images of acetylated-tubulin expression in the heads of zebrafish embryos injected with a control or six6a morpholino, rescued by co-injection with human non-risk SIX6 transcript or a transcript containing the Leu205Arg hypomorphic variant (A). Acetylated-tubulin staining is restricted primarily to axon tracts and can be used to visualize the optic nerve. Relative to the control morphants, volumetric regions of interest (ROI) along the optic nerve in six6a morphants were reduced significantly. Co-injection of human variants revealed a hypomorphic (Leu205Arg, Asn141His) or benign (Glu93Gln) role of the variants on the optic nerve (B). Sample size for all injection paradigms ranged from 7–9 and p-values are plotted for each comparison (*** p<0.001; ** p<0.01). No significant changes in the volume of other axonal tracts in the head (marked by an asterisk) were detected. Standard error of the mean is shown and white scale bars = 20 μm.
