Differentially expressed genes overlapping across the datasets GSE122063, GSE5281, and GSE132903 were enriched in biological processes involved in AD, mTOR signaling, and Ras signaling (Figure 3A), including purine nucleoside triphosphate metabolism, cellular respiration, and nucleoside triphosphate metabolism (Figure 3B). This evidence concerns the gene MTOR and Alzheimer disease.
