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)
Measurement of the inhibitory potency of non-steroidal anti-inflammatory drugs on cyclooxygenase isoforms is strongly influenced by variations in experimental conditions, the concentration of protein in the assay medium being particularly important because these drugs are highly protein bound in vivo so that assays based on human whole blood provide the most suitable test system, and of the drugs investigated only meloxicam showed selectivity for cyclooxygenase-2 at therapeutically relevant concentrations while standard drugs such as naproxen inhibited both isoforms to an equal degree.
