AD mice exhibit altered protein synthesis and oxidative stress metabolic pathways in the hippocampus. (a) A heat map expressing the normalized peak area concentrations of the top 9 metabolites that are changed between Ctrl and AD mice across age in the HPC. Green indicates greater concentration and red indicates weaker concentration. (b–j) Top 9 metabolites significantly upregulated or downregulated between Ctrl and AD mice in the HPC at different ages. These metabolites are in the aminoacyl-tRNA biosynthesis (l-methionine, isoleucine, tyrosine, arginine); glutathione (glutathione, pyroglutamic acid); and glyoxylate and dicarboxylate (hydroxypyruvic acid, glycolic acid, glyceric acid) metabolic pathways. (n = 3–6 male mice per group). Error bars represent ± SEM. *p < 0.05; **p < 0.01; ***p < 0.001. Ctrl control, AD Alzheimer’s disease.
