Vascular endothelial growth factor receptor 2 / KDR
Vascular endothelial growth factor receptor 2 / KDR. Species, exposure and limitations are retained in each linked claim.
3 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
Mebendazole was determined to interfere with vascular endothelial growth factor receptor 2 kinase by competing with ATP, selectively inhibited tumour angiogenesis but not the normal brain vasculature in orthotopic medulloblastoma models, suppressed the kinase in vivo, and significantly extended survival of medulloblastoma models derived from different molecular backgrounds including a PTCH1-mutant tumour with acquired resistance to the smoothened inhibitor vismodegib.

Complete structured claim and evidence
Where it participates (unsigned role)
Colony-forming cells rose from 16 to 26 per 100,000 monocytes plated, entirely due to the CD34-positive subpopulation, and a high proportion of progeny cells expressed receptors for vascular endothelial growth factor-2 and for stromal-derived growth factor.
