In addition, regarding neurodegenerative diseases (NDDs), several functions, including Huntington’s disease signaling (EGFR, MAPK1, PSMB3), neuroprotection by THOP1 in Alzheimer’s disease (AGT, MAPK1) and Parkinson’s signaling (MAPK1), were activated only in aged mice (Supplementary Table S6). This evidence concerns the gene PSMB3 and Parkinson disease.
