Component
Resveratrol
Context-specific entity; species, compartment and exposure are stated on each claim.
68 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 it acts on
Resveratrol at 300 micromolar for 30 minutes reduced alanine-evoked short-circuit current in isolated porcine intestinal preparations.

## resveratrol-sirt1-native-null Some original activation assays depended on the artificial reporter. Resveratrol did not activate human SIRT1 on the tested unlabelled p53 peptide or full-length p53 and acetyl-CoA-synthetase substrates, while fluorophore-tagged peptide assays showed activation. Model: Biochemical comparison of labelled and native substrates. Limitations: This is a negative result for tested substrates, not proof that no native sequence can respond.

## resveratrol-ugt-substrate-selectivity The interaction depends on the enzyme substrate. Trans-resveratrol inhibited SN-38 glucuronidation in human enzyme experiments (Ki 6.2 ± 2.1 micromolar), while bilirubin glucuronidation showed no major change. Model: Human microsomal/recombinant assays. Limitations: Not demonstrated irinotecan toxicity or a clinical dose-adjustment rule.
