⚖️ Evidence

⚖️ Evidence Matrix4 supports4 contradicts
Supports
MPC1 mRNA upregulation in human AD brain (computational: GTEx Brain Tissue Expression Database)
Supports
Pharmaceutical MPC inhibition protects against ischemia-reperfusion injury by activating protective metabolic pathways
Supports
Forcing ketone body utilization activates BDNF signaling and enhances mitochondrial biogenesis
Supports
Cancer metabolism literature confirms MPC inhibition shifts cells toward glutamine and fatty acid oxidation
Contradicts
MPC1 mRNA upregulation is computational annotation, not peer-reviewed validation - foundational claim lacks rigorous support
Contradicts
MPC inhibition reduces neuronal firing rates in vitro - neurons are highly dependent on glucose-derived pyruvate oxidation
Contradicts
Forcing ketone utilization in already-metabolically-compromised neurons risks acute energy failure
Contradicts
Cancer metabolism literature does not translate directly - adult neurons are post-mitotic with different metabolic priorities

🔮 Falsifiable Predictions (2)

IF C57BL/6J mice on a high‑fat diet receive daily intraperitoneal injections of the MPC inhibitor MSDC‑0160 (10 mg/kg) for 14 days THEN plasma β‑hydroxybutyrate levels will rise by at least 50 % compared to vehicle‑treated controls within 4 h after the final injection.
Predicted outcome: ≥50% increase in plasma β‑hydroxybutyrate (βHB) relative to vehicle‑treated mice.
Falsification: Plasma βHB does not increase (≤10% change) or decreases relative to vehicle control.

IF primary human hepatocytes cultured in Williams’ E medium supplemented with 1 mM octanoate are treated with 10 µM MSDC‑0160 for 48 h THEN extracellular ketone bodies (acacetate + βHB) increase by ≥2‑fold and glucose consumption decreases by ≥30 % relative to DMSO‑treated controls.
Predicted outcome: ≥2‑fold increase in extracellular ketone bodies; ≥30% reduction in glucose consumption.
Falsification: Extracellular ketone bodies show <1.2‑fold change and/or glucose consumption does not decrease by at least 30%.
