Individuals with high AD polygenic risk score (PRS) show earlier onset and steeper progression of the mouse-defined transcriptomic aging program (CARS, Section 24), corresponding to 5-10 additional years of molecular aging. This convergence arises because all 8 AD GWAS hits found in the mouse aging DEG set (TREM2, TYROBP, APOE, CLU, C4B, PICALM, BIN1) are upregulated in the same direction as disease pathology — indicating that genetic risk and chronological aging activate identical transcription
## Mechanistic Overview
SIRT1 (Sirtuin 1), a class III NAD+-dependent histone deacetylase, functions as a master metabolic sensor that couples cellular energy status to transcriptional programs governing longevity and stress resistance. In healthy microglia, SIRT1 maintains cellular homeostasis through deacetylation of key transcriptional regulators including PGC1α, p53, and FOXO transcription factors. During aging, declining NAD+ levels and oxidative stress lead to SIRT1 downregulation, trigge
