Hypothesis
Metabolic Rescue PDH Activation (H5): Indirect Lipogenesis Suppression
Dichloroacetate-mediated PDH activation redirects pyruvate into TCA cycle, reducing NADPH and acetyl-CoA substrate supply for de novo lipogenesis.

🧪 Overview
Dichloroacetate-mediated PDH activation redirects pyruvate into TCA cycle, reducing NADPH and acetyl-CoA substrate supply for de novo lipogenesis. Metabolic correction approach that bypasses direct AMPK targeting. Weak CNS pharmacology and non-neuron-specific effects limit utility; requires neuron-specific validation.

🔮 Falsifiable Predictions (2)
pendingconf 55%
IF primary cortical neurons or iPSC-derived dopaminergic neurons are treated with dichloroacetate at concentrations ≥0.5 mM (achieving PDH activation), THEN de novo lipogenesis will be suppressed, as measured by reduced 14C-acetate incorporation into lipid fractions, within 48-72 hours of continuous
Predicted outcome: ≥40% reduction in lipid synthesis rate (14C-acetate incorporation) and ≥30% decrease in FASN (fatty acid synthase) protein expression relative to vehi
Falsification: Lipid synthesis rates remain unchanged (<10% change) or increase despite documented PDH activation (pPDHA1 increase ≥50%), contradicting substrate diversion theory.
pendingconf 48%
IF PDH is activated by dichloroacetate in neurons (≥0.5 mM), THEN intracellular NADPH and acetyl-CoA pools will be reduced (depleting lipogenesis substrates), measurable via targeted metabolomics, within 24-48 hours.
Predicted outcome: ≥25% decrease in NADPH levels and ≥30% reduction in acetyl-CoA concentration relative to vehicle controls, with reciprocal ≥50% increase in TCA cycle
Falsification: NADPH and acetyl-CoA levels remain stable or increase despite confirmed PDH activation, indicating alternative metabolic routing that does not deplete lipogenesis precursors.
