(A) HA-SHANK1 (WT, Gly1105fs, or Glu1119*) was
transfected in cultured rat hippocampal neurons. HA-SHANK1 was labeled with
anti-HA and Alexa 555-conjugated secondary antibody (white). Enlarged images of
the boxed regions are shown below each panel. Dashed regions indicate soma.
(Scale bar, 25 μm.) (B) HA-SHANK1 (WT, Gly1105fs, or
Glu1119*) was expressed in cultured rat hippocampal neurons. HA-SHANK1 was
labeled with anti-HA and Alexa 555-conjugated secondary antibody (red).
Endogenous PSD-95 was labeled with anti-PSD-95 and Alexa 488-conjugated
secondary antibody (green). Regions from three dendrites per each neuron were
analyzed for Pearson’s coefficient. Graph indicates mean ± SEM (n
= 15~19). *P < 0.05, ***P < 0.0005, ****P < 0.0001
using one-way ANOVA with Dunnett’s multiple comparison test. (Scale bar,
5 μm.)
