Knockdown of δ-catenin perturbs spine architecture in mature neurons.
a, representative images of dendrites expressing vector, shRNA, or shRNA + δ-catenin*, transfected at DIV 14 and fixed at DIV 21 (density, 75,000 neurons per coverslip). b, spine head width and c, spine length in neurons expressing vector, shRNA, or shRNA + δ-catenin* (p values: *, <0.05; **, <0.005; ***, <0.0005, one-way ANOVA analysis and Dunnett's multiple comparison test with single pooled variance; scale, 5 μm).
