Comparative epigenetic signatures: DNA methylation age acceleration and histone modifications across AD, PD, and ALS

PARTIALLY ADDRESSED

Investigate shared DNA methylation age acceleration and histone modification patterns (H3K27me3, H3K4me3, H3K9me3, acetylation) across Alzheimer disease, Parkinson disease, and ALS. Identify common epigenetic signatures that distinguish these neurodegenerative diseases from normal aging.
