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.

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.

  2. Sodium salicylate inhibited activation of nuclear factor kappa B by preventing phosphorylation and subsequent degradation of I-kappa-B-alpha without affecting tumour necrosis factor alpha-induced phosphorylation of ATF-2, blocked the increase in adhesion molecule messenger RNA and gave dose-dependent inhibition of surface vascular cell adhesion molecule 1 and intercellular adhesion molecule 1 with higher doses required for endothelial-leukocyte adhesion molecule 1, and inhibited transendothelial migration of neutrophils; indomethacin, a nonsalicylate cyclooxygenase inhibitor, had no effect on surface expression, suggesting the effects were not due to inhibition of cyclooxygenase.
