Hypotheses

#HypothesisTargetScorePrice
#1 Chaperone-Mediated APOE4 Refolding Enhancement HSPA1A, HSP90AA1, DNAJB1, FKBP5 0.607 $0.61
Upregulating specific molecular chaperones (HSP70, HSP90) or co-chaperones could enhance proper APOE4 folding and prevent domain interaction. This approach would leverage endogenous quality control me...
#2 Targeted APOE4-to-APOE3 Base Editing Therapy APOE 0.583 $0.58
CRISPR-based cytosine base editors could precisely convert the C334T mutation back to wild-type, effectively transforming APOE4 carriers into APOE3 genotype. This would eliminate the root cause of dom...
#3 APOE4 Allosteric Rescue via Small Molecule Chaperones APOE 0.575 $0.57
Small molecules targeting the hinge region between APOE4 domains could stabilize the native APOE3-like conformation, preventing pathological domain interaction. These allosteric modulators would resto...
#4 Selective APOE4 Degradation via Proteolysis Targeting Chimeras (PROTACs) APOE 0.528 $0.53
Engineered PROTACs could selectively recruit APOE4 (but not APOE3) to E3 ligases for ubiquitin-mediated degradation, based on the unique structural features of domain-interacted APOE4. This would redu...
#5 Competitive APOE4 Domain Stabilization Peptides APOE 0.481 $0.48
Cell-penetrating peptides designed to mimic the N-terminal domain could competitively bind to the C-terminal domain of APOE4, preventing pathological self-interaction. These peptides would act as mole...
#6 Interfacial Lipid Mimetics to Disrupt Domain Interaction APOE 0.437 $0.44
Synthetic lipid-like molecules could competitively bind to the aberrant interdomain interface of APOE4, forcing domains apart and restoring normal lipid binding conformation. These molecules would mim...
#7 Pharmacological Enhancement of APOE4 Glycosylation ST6GAL1, FUT8 0.432 $0.43
Modulating glycosyltransferases could add stabilizing glycan modifications to APOE4, preventing domain interaction through steric hindrance. Enhanced sialylation or fucosylation could specifically tar...
