Description

Healthy astrocytes maintain motor neuron metabolic homeostasis through lactate export via monocarboxylate transporters (MCT1/MCT4), providing energy substrates that support nuclear import machinery and RNA processing. Hypoxic VCP-mutant astrocytes undergo metabolic reprogramming reducing pyruvate dehydrogenase activity and lactate export, impairing ATP-dependent nuclear import of TDP-43/FUS.

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.
