Component
GCH1 mRNA
Transcript abundance; distinct from protein abundance or measured catalytic flux.
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.
Where it participates (unsigned role)
ATRA increased GPX4/FSP1 protein and GCH1 transcripts; RAR blockade suppressed the transcript responses.
Experimental context and source evidence
- cross_nutrient
- Shared GPX4 connects retinoid signaling to the selenium collection; no proven supplementation synergy.
- experimental_model
- HT-1080 cells; pharmacological ATRA.
- limitations
- Direct promoter binding and dietary selenium replacement were not tested.
- nutrient_topic
- Vitamin A research collection; topical membership is not evidence of a direct dietary effect. · Vitamin A
- organism
- Homo sapiens
