Sirt3 levels were reversely related to AD tau pathology in MTG. Sirt3 levels were analyzed for correlation with tau pathology. Pearson’s correlation curve was shown. In MTG, Sirt3 levels were correlated with a NFT score in MTG, b soluble tau protein level in MTG, and c Braak stage. In SFG, the correlations with Sirt3 levels were assessed in d NFT score in SFG, e soluble tau protein level in SFG, and f Braak stage
