## Mechanistic Overview
NMN Supplementation Restores SIRT1/p66Shc/FOXO3 Epigenetic Axis and Dopaminergic Neuron Survival in Parkinson's Disease Models starts from the claim that modulating SIRT1/NAD+ axis within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "**Molecular Mechanism and Rationale** The proposed therapeutic mechanism centers on the restoration of the NAD+/SIRT1 epigenetic regulatory axis in dopaminergic neurons of t
**Molecular Mechanism and Rationale**
The polycomb repressive complex 2 (PRC2) represents a fundamental epigenetic regulatory system that becomes dysregulated in Alzheimer's disease (AD), leading to pathological silencing of genes essential for synaptic function and neuronal survival. The core catalytic component of PRC2, enhancer of zeste homolog 2 (EZH2), functions as a histone methyltransferase that specifically targets lysine 27 of histone H3 (H3K27me3), creating a repressive chromatin mark
