⚖️ Evidence Matrix5 supports1 contradicts
Supports
REST and REST-dependent programs in neuronal gene regulation and disease.
Supports
REST deficiency drives tau pathology through dysregulation of synaptic and neuronal genes.
Supports
REST regulates tau and neurodegenerative gene programs in aging brain.
Supports
REST is a critical regulator of neuronal genome and proteostasis in aging.
Supports
Loss of REST function in neurodegeneration leads to synaptic gene dysregulation.
Contradicts
This program may emerge too late to explain the primary suppressive event.

IF human iPSC-derived cortical neurons are treated with proteasome inhibitor (MG-132, 1 µM) for 48 hours to induce severe proteostatic stress, THEN REST mRNA and protein levels will increase by >2-fold (p<0.01) and MAPT mRNA will decrease by >40% compared to vehicle-treated neurons within 72 hours p
Predicted outcome: REST protein levels increase 2.2-3.0 fold; MAPT mRNA decreases 40-60% (qPCR) and soluble tau protein decreases 30-50% (ELISA) relative to vehicle cont
Falsification: REST does not increase (fold change <1.5) OR MAPT mRNA does not decrease significantly (<20% change, p>0.05) despite confirmed proteasome inhibition (accumulation of ubiquitinated proteins)

IF REST is knocked down via shRNA in primary mouse cortical neurons prior to proteasome inhibition (lactacystin, 5 µM), THEN tau protein levels will remain elevated (no suppression) and neurons will show significantly higher tau aggregation markers (+50-100%) compared to control shRNA neurons under

Falsification: REST knockdown does not prevent tau suppression (tau still decreases >25% despite confirmed REST knock-down efficiency >70%)
