Lack of mGluR5 decreases PSD95 expression in aged mice. Graphs show PSD95 (A, B and C) mRNA levels in the hippocampus of wild-type (WT), BACHD, mGluR5−/− and BACHD/mGluR5−/− mice at 2 (n = 4) (A), 6 (n = 4) (B) and 12 (n = 6) (C) months of age. mRNA levels were assessed by RT-qPCR, which was performed in triplicate and normalized to actin mRNA levels. Data represent the means ± SEM. *p < 0.05 and ***p < 0.01 by one-way ANOVA and Bonferroni's multiple comparisons test.
