🔮 Falsifiable Predictions (2)
pendingconf 35%
IF recombinant tau protein is pre-treated with neuraminidase (to remove terminal sialic acid residues) PRIOR to aggregation induction, THEN Thioflavin-S fluorescence signal at 48 hours will be reduced by at least 30% compared to untreated tau controls.
Predicted outcome: Thioflavin-S fluorescence signal ≤70% of vehicle-treated tau aggregation controls
Falsification: No reduction (≥95% of control) or increase in Thioflavin-S signal in neuraminidase-treated tau samples at 48 hours, indicating sialic acid removal does not inhibit tau aggregation
pendingconf 30%
IF NEU1 is overexpressed (≥3-fold endogenous levels) in human neuroblastoma cells inducibly expressing tau, THEN extracellular tau concentration in conditioned media at 72 hours will decrease by at least 40% compared to vector-transfected cells.
Predicted outcome: Extracellular tau ELISA signal reduced to ≤60% of vector control levels, with corresponding increase in intracellulartau showing impaired secretion
Falsification: Extracellular tau levels unchanged or increased (≥95% of vector control) at 72 hours, indicating NEU1 activity does not modulate tau secretion
