From Analysis:

Metabolomic signatures of neurodegeneration: metabolic reprogramming in aging brains

What are the key metabolic alterations detectable in brain tissue, CSF, and blood during neurodegeneration, and can metabolomic biomarkers predict disease progression before clinical symptoms appear? How does the brain's metabolic landscape shift from glycolysis toward alternative energy substrates in AD, and what does this reveal about bioenergetic failure as a driver versus consequence of pathology?

Dimension Scores

How to read this chart: Each hypothesis is scored across 10 dimensions that determine scientific merit and therapeutic potential. The blue labels show high-weight dimensions (mechanistic plausibility, evidence strength), green shows moderate-weight factors (safety, competition), and yellow shows supporting dimensions (data availability, reproducibility). Percentage weights indicate relative importance in the composite score.

Therapeutic Hypotheses: Metabolomic Signatures of Neurodegeneration

Hypothesis 1: Restoration of Neuronal Ketone Body Utilization via MCT1 Upregulation

Title: MCT1 transporter upregulation as a therapeutic strategy to compensate for cerebral glucose hypometabolism in Alzheimer's disease

Description: Neuronal MCT1 (SLC16A1) expression declines in AD brain, limiting utilization of circulating ketone bodies as alternative fuel. Therapeutic upregulation of neuronal MCT1 using novel brain-penetrant small molecules could restore ketonemia-derived ATP production in neurons suff

Hypothesis 1: MCT1 Upregulation for Ketone Body Utilization

Specific Weaknesses

1. Causal Direction Ambiguity: The cited reduction in MCT1/MCT4 protein (PMID:25716827) may represent a compensatory downregulation to reduce lactate export from metabolically compromised cells, rather than a primary pathogenic mechanism. Without demonstrating that

Drug Discovery Assessment: Metabolomic Hypotheses for Neurodegeneration

Executive Summary

All seven hypotheses face significant translational barriers. The metabolomics field provides genuine mechanistic insight but suffers from over-reliance on postmortem data, species translation gaps, and absence of validated CNS pharmacodynamic biomarkers. No hypothesis has a clear path to IND-enabling studies within standard timelines.
