Figure 1: Increase in free D-aspartate level of the hippocampus after soy peptide ingestion. Hippocampal D-aspartate levels of SDDM (A) and C57BL/6J wild type (B) mice were measured as described in the Materials and Methods. Data represent the mean amino acid content ± S.E. (SDDM mice: n = 5 for the ROW group; n = 4 for SOY group; n = 4 for the SER group; C57BL/6J mice: n = 4 for the ROW group; n = 6 for the SOY group; n = 5 for the SER group). Differences between treatments were analyzed by one-way ANOVA, Dunnett’s post-hoc test (*, p < 0.05; **, p < 0.005; † indicates p = 0.06).
