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)
Geranylgeraniol fully reverted statin-mediated loss of myoblast viability, while water-soluble cholesterol did not, and statins caused loss of prenylated RAP1.
Experimental context and source evidence
- duration
- Not stated here
- evidence_access
- Primary PubMed abstract and indexed metadata reviewed. Full-text method details not stated here remain unresolved.
- experimental_model
- Murine C2C12 myoblasts
- exposure
- Geranylgeraniol, farnesol, mevalonate or water-soluble cholesterol co-treatment with statin
- limitations
- Cholesterol rescued only methyl-beta-cyclodextrin toxicity, and geranylgeranyltransferase inhibition with GGTI-286 could not be reversed by geranylgeraniol, so the rescue requires the transferase to be intact.

Original AI-assisted curation of twelve primary studies resolved by PubMed title search and cross-checked against live PubMed metadata. Findings obtained with mevastatin, simvastatin or the statin class are recorded against those subjects. Study-specific citations, doses, negative findings and limitations retained.
