Mechanistic description

Mitochondrial Pyruvate Carrier Inhibition to Force Metabolic Reprogramming Toward Ketone Utilization

Mechanism / pathway

MPC1/MPC2

metabolomics

Evidence for (4)

MPC1 mRNA upregulation in human AD brain (computational: GTEx Brain Tissue Expression Database)

PMID:GTEx
Pharmaceutical MPC inhibition protects against ischemia-reperfusion injury by activating protective metabolic pathways

PMID:29425851
Forcing ketone body utilization activates BDNF signaling and enhances mitochondrial biogenesis

PMID:25516598
Cancer metabolism literature confirms MPC inhibition shifts cells toward glutamine and fatty acid oxidation

PMID:24393791

Evidence against (4)

MPC1 mRNA upregulation is computational annotation, not peer-reviewed validation - foundational claim lacks rigorous support
MPC inhibition reduces neuronal firing rates in vitro - neurons are highly dependent on glucose-derived pyruvate oxidation

PMID:29425851
Forcing ketone utilization in already-metabolically-compromised neurons risks acute energy failure
Cancer metabolism literature does not translate directly - adult neurons are post-mitotic with different metabolic priorities
