CNF1 counteracts the impaired dendritic
branching in glioma-bearing mice. (A) Representative Thy1-GFP neurons (green) in a
Hoechst-stained coronal section through the mouse primary visual cortex. Tumor
borders are indicated by the dotted line. Dorsal is up and lateral is to the right.
Scale bar = 500 µm. (B) Neurolucida tracings of representative Thy1-GFP pyramidal
neurons in naïve, vehicle-, and CNF1-treated glioma-bearing animals. Scale bar = 10
µm. (C) Box charts showing total dendritic length for neurons from glioma-bearing
mice. The horizontal dotted line represents the median value observed in naïve mice
for comparison. Dendritic length is significantly increased in CNF1- vs
vehicle-treated mice (Mann–Whitney rank sum test, *P < .05). (D)
Sholl analysis of layer V pyramidal neurons in naïve, vehicle-, and CNF1-treated
glioma-bearing mice. CNF1 treatment maintains a higher number of intersections close
to the cell soma (2-way repeated measures ANOVA followed by Holm–Sidak test,
10-20-30 µm from soma, CNF1 vs vehicle, *P < .05). Data are mean
± SEM.
