The quantitative data from F and G represent CMTR1 intensity, dendritic number, and dendritic length in control and Cmtr1siRNA knockdown groups. Data were analyzed from at least six different areas of three independent experiments. Statistic: Student’s unpairedttest (H–K). Values represent the mean ± s.e.m., *P< 0.05, **P< 0.01, ***P< 0.001, ****P< 0.0001.
