NORAD's evolutionarily conserved 5' stem-loop (nt 1-180) scaffolds multiple PUMILIO binding motifs in a structured context. Selective ASO targeting releases PUMILIO repression of mitotic genes (CHEK1, TOP2A, KIF15), restoring genomic stability. Among proposed targets, NORAD has the strongest primary evidence for structural conservation across primates and rodents (Tichon et al., 2016) and demonstrates clear mechanistic link between structure and function (PUMILIO binding requires structured NORA
**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
