IF human iPSC-derived neurons carrying tau mutations are treated with 2-deoxy-D-glucose (2-DG) analog at 500 μM for 72 hours, THEN aberrant sialyl-LewisX glycosylation on tau vesicles will decrease by >40% while total cellular protein glycosylation will change by <15%.
Predicted outcome: Reduction in pathological sialyl-LewisX epitope on isolated tau vesicles (measured by lectin blot or mass spectrometry) by >40% with selectivity ratio
Falsification: No differential effect: both pathological tau glycosylation and normal cellular glycosylation change by <20% (indicating lack of therapeutic window) OR pathological tau glycosylation increases rather

IF SH-SY5Y cells with doxycycline-inducible mutant tau expression are subjected to HK1 knockdown via siRNA for 48 hours, THEN the abundance of high-mannose N-glycans on purified tau vesicles will decrease by >50% compared to non-induced controls.
Predicted outcome: Significant reduction in high-mannose N-glycan structures (Man5-Man9 species) on tau vesicles isolated from HK1-knockdown cells, quantified by quantit
Falsification: Tau vesicle glycan composition shows <20% change in high-mannose structures after HK1 knockdown, indicating HK1 is not the critical metabolic node controlling tau glycosylation
