Moreover, we evaluated whether the biomarkers found to be important for classifying AD are enriched with those shown to be related to aging by being identified as part of aging clock models, differentially regulated by age [62,63,64,65,66,67,68,69,70,71], or among those identified in the Human Ageing Genomic Resources (HAGR) database (GenAge, CellAge and cell senescence signatures) [72,73]. Here, CLOCK is linked to Alzheimer disease.
