SOD1, TDP-43, and FUS pathology may converge on impaired iron buffering in motor neurons and glia, increasing labile iron that catalyzes lipid peroxide propagation. Biomarker-guided iron buffering should benefit only the subgroup with demonstrable iron and lipid-peroxidation elevation.
ALS-linked proteostasis stress lowers effective GPX4 reserve in vulnerable motor neurons, allowing oxidized phospholipids to cross a ferroptotic death threshold. Restoring GPX4 activity or glutathione availability should rescue motor-neuron survival more strongly than generic antioxidants.
Convergent vs Divergent Predictions
This summary checks where the selected hypotheses point toward the same target or mechanism, and where they pull in opposite directions.
No same-target convergence detected in this selection.
Divergent signals

Three mechanisms deserve priority: loss of GPX4 reserve in stressed motor neurons, ACSL4/LPCAT3-driven enrichment of oxidizable PUFA phospholipids, and genotype-specific iron mishandling in SOD1/TDP-4...

The key weakness is causal ordering. Lipid peroxidation appears in many dying neurons, so experiments must show that ferroptosis blockade rescues motor-neuron survival after controlling for apoptosis,...

Translation requires biomarkers before treatment trials: CSF/plasma 4-HNE, F2-isoprostanes, oxidized PE species, GPX4 activity, and iron MRI should stratify patients. Deferiprone-like strategies need ...

Ranked synthesis: prioritize GPX4 reserve failure, then PUFA-phospholipid substrate loading, then labile iron pool expansion. The program should demand orthogonal death-pathway exclusion and genotype-...
