The effect of diabetes on metabolic pathway changes in different brain regions of mice. Metabolites showing a statistically significant diabetic effect (P < 0.05) were highlighted in metabolic pathways and colored according to their fold changes (T1D/CON). Metabolite abbreviation: ADP, adenosine diphosphate; Ala, alanine; AMP, adenosine monophosphate; Asp, aspartate; Cho, choline; Cre/pCre, creatine/phosphocreatine; GABA, γ-Aminobutyric acid; Gln, glutamine; Glu, glutamate; Gly, glycine; IMP, inosine monophosphate; Ino, inosine; Lac, lactate; Myo, myo-inositol; NAA, N-acetylaspartate; NAD+, nicotinamide adeninedinucleotide; Suc, succinate; Tau, taurine. Brain regions: Hip, hippocampus; Cor, cortex; Cer, cerebellum; Str, Striatum; Hyp, hypothalamus; Mid, midbrain.
