Conserved G-quadruplex structures in HOTAIR's 5' PRC2-binding region create ASO-accessible windows for selective disruption of EZH2/SUZ12 occupancy while preserving LSD1 interactions. This differential targeting enables derepression of PRC2-targeted tumor suppressors without complete HOTAIR loss. Partial structural conservation is documented (Somarowthu et al., 2015), and G-quadruplex ligands modulate HOTAIR levels, suggesting pharmacological tractability.
**Background and Rationale**
Alzheimer's disease (AD) pathogenesis is intimately linked to apolipoprotein E (APOE) isoform-dependent differences in amyloid-beta (Aβ) clearance and lipid metabolism. The APOE4 allele, present in approximately 25% of the population and 65% of AD patients, confers the highest genetic risk for late-onset AD. Unlike APOE2 and APOE3, APOE4 exhibits significantly reduced lipidation capacity and impaired Aβ clearance efficiency. This stems from structural differences in
