Component
Rat thoracic aortic ring tension
2 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
Nattokinase relaxed rat thoracic aortic rings dose-dependently, and the relaxation required an intact endothelium.

Nattokinase: what the purified enzyme cleaves, what survives being eaten, and the gap between the two (2026-09-23) · lines 400–400
Original AI-assisted curation built from a supplied entity-first document of 105 entities and 129 claims. Every reference in that document was resolved against live PubMed with its abstract read and its DOI cross-checked on 2026-09-23, and the EFSA novel-food opinion was retrieved and read in full. That check corrected two PMIDs that pointed at unrelated papers, two DOIs, and two papers recorded as carrying no erratum that do carry one; it also reversed three findings the supplied document had stated backwards. Two papers carry a published correction, recorded as such and not as a retraction. Three sources are not indexed in PubMed and are cited by what they have. Laboratory lineages are recorded, so the four papers from one group, the three from another and the two readings of a single applicant dossier cannot be counted as separate lines of support. Study-specific doses, units, populations and limitations retained; activity units are never converted between systems.

- Recorded under a blocked pathway: the finding is what happens when NOS is inhibited. The isoform is not identified, and indomethacin was tested in the same design without its result being separable from the abstract.
