AQP4 isoform content in GBM samples control (N), peritumoral (Pt) and tumoral (T) regions. a Violin plots reporting data distribution of the M23ex isoform amount relative to the total AQP4 content measured by immunoblotting. b Plots reporting M1ex isoform (37 KDa) content relative to the total AQP4ex measured by immunoblotting using anti-AQP4ex antibody. c M1 expression levels. Blue, green and red dotted lines represent the upper and lower quartile in each distribution. a ANOVA-one way, Tukey's multiple comparisons test, *p < 0.05, ***p < 0.0001. b, c Kruskal–Wallis, post-test: Dunn's multiple comparisons test, *p < 0.05
