## **Molecular Mechanism and Rationale**
SUV39H1 (Suppressor of Variegation 3-9 Homolog 1), also known as KMT1A (lysine methyltransferase 1A), functions as the primary histone methyltransferase responsible for catalyzing the trimethylation of histone H3 at lysine 9 (H3K9me3), a critical epigenetic mark for heterochromatin formation and maintenance. This enzyme operates through a highly conserved SET (Su(var)3-9, Enhancer-of-zeste, Trithorax) domain that transfers methyl groups from S-adenosylme

## **Molecular Mechanism and Rationale**
The FOXO3-SIRT1 regulatory axis represents a sophisticated cellular defense mechanism that maintains genomic stability through heterochromatin preservation during oxidative stress in aging neurons. FOXO3 (Forkhead Box O3) functions as a master transcription factor that orchestrates cellular responses to environmental stressors, while SIRT1 (Sirtuin 1), a NAD+-dependent deacetylase, serves as its primary post-translational modifier.
