Axonal regeneration: immunoblotting of (A) ON and (B) retina samples obtained from 18 MPS/9 MPI of control-Veh-ttd, EAE-Veh-ttd, and EAE-Klf4fl/fl-Cre-ttd mice shows expression of GAP43 (top panels) and GAPDH (bottom panels) in all samples. GAP43 band intensities were higher in EAE-Klf4fl/fl-Cre-ttd mice compared with control or EAE Veh-ttd mice. Corresponding box-whisker plots at the bottom of the blots shows the ImageJ-based quantitative analysis of GAP43/GAPDH expression in ON and retina among three groups. Samples derived from the same experiment and that gels/blots were processed in parallel for quantitative analysis. Statistical analysis was performed by one-way ANOVA followed by Tukey’s multiple comparison test, a p < 0.05 is considered to be statistically significant; ****p < 0.0001–0.0009 (n = 6 eyes/group, experimental repeats = 3).Figure Contributions: Venu Talla acquired the data, analyzed, and generated the figure.
