Ergothioneine concentration in mouse gastrocnemius muscle
1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What acts on it
PGC-1alpha-overexpressing mouse muscle contained more ergothioneine than control muscle.
Experimental context and source evidence
- evidence_access
- Publisher abstract/introduction plus the authors' article and supplementary legends reproduced in an indexed document. This is source-derived extraction, not raw-data verification. Main-text OCR corrupts some micro-unit symbols; ambiguous doses and binding constants are deliberately not transcribed.
- experimental_condition
- wild-type mice muscle overexpression · Mouse PGC-1alpha / Ppargc1a Condition belongs to the full experimental contrast; do not separate a joint intervention.
- experimental_contrast
- {"intervention": "muscle-specific PGC-1alpha overexpression", "comparator": "wild-type mice", "endpoint": "whole-muscle ergothioneine concentration", "effect_direction": "increase", "combination": "single", "conditions": [{"entity_slug": "mouse-ppargc1a", "state": "muscle overexpression"}]} Explicit extracted experimental comparison; source-derived draft.
- experimental_model
- MCK-PGC-1alpha mice; whole gastrocnemius metabolomics.
- interpretation_status
- Source-derived research curation; not independent raw-data verification.
- limitations
- Whole-muscle concentration is not the isolated mitochondrial pool. This does not establish that transporter upregulation is the only causal route.
- nutrient_topic
- Ergothioneine mitochondrial supplement; shared molecular requirements are not demonstrated dietary interactions. · L-Ergothioneine
- plain_language
- The muscle pool changed alongside transporter expression.
