NEAT1_2's conserved A-rich bulges (reported at nt 2500-3500) nucleate paraspeckle assembly via NONO-PSPC1 binding. ASOs targeting bulges without invading base-paired stems would selectively disrupt paraspeckle formation. However, NEAT1 conservation is poor (~40% human-mouse identity), and the specific bulge coordinates fall within a highly variable repeat region. Expert assessment concluded conservation claims are contradicted by primary literature.
**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
