Strychnine, an antagonist of the glycine receptor induces the same effects as extracellular cGMP on membrane expression and occludes the effect of cGMP on membrane expression of GluA1 and GluA2. Strychnine (75 µM), an antagonist of glycine receptor, alone or in combination with extracellular cGMP (40 nM) were added to cerebellar slices, and membrane expression of GluA1 (A and C) and GluA2 (B and D) subunits were analyzed as described in Methods. Values are expressed as percentage of basal and are the mean ± SEM of 8–16 rats (in A and B) and of 7–12 rats (in C and D). The unpaired Student’s t-test and non-parametric Kruskal-Wallis test were performed to compare two or more groups, respectively. Values significantly different from basal are indicated by asterisks *p < 0.05, **p < 0.01, ***p < 0.001.
