Basic fibroblast growth factor / FGF2: molecular mechanisms & dependencies

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.

Human evidence only

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.

Recorded relationships

Where it participates (unsigned role)

Treatment increased tissue levels of the angiogenesis markers EGF, VEGF, PDGF, FGF-2 and CXCL10, and Nrf2 correlated positively with EGF, VEGF and PDGF.

A small randomised human study with tissue-level molecular endpoints. Correlations between Nrf2 and growth factors are associations within treated tissue.

Treatment significantly increased nitrate, VEGF and basic fibroblast growth factor levels and stabilised HIF-1alpha within one day, promoting blood vessel formation at 3 to 7 days and muscle healing at 5 to 7 days after contusion.

experimental_model
Contused rat skeletal muscle with a reactive oxygen species scavenger and a nitric oxide synthase inhibitor
exposure
2.5 ATA 100% oxygen for 120 minutes daily for 5 consecutive days
limitations
Both inhibitors were given before treatment, which is what makes the requirement claim interpretable. The exposure is a therapy-like protocol, unlike the extreme-pressure studies recorded elsewhere here.
