Component

Reconstructed 1-, 6- and 24-hour human C3G metabolite signatures

Reconstructed 1-, 6- and 24-hour human C3G metabolite signatures. Interpret through the linked experimental species, preparation, compartment and exposure; no universal causal effect is implied.

6 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.

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.

    **Low-concentration mixtures can change VCAM-1 without a universal IL-6 effect.** Warner's 2017 study reconstructed the tracer cohort's 1-, 6- and 24-hour serum signatures. Mixtures reduced TNF-stimulated VCAM-1; some effects remained at total concentrations of 0.19–0.44 µM. IL-6 secretion decreased in HUVECs at selected higher mixture concentrations, but not detectably in HCAECs. TNF stimulation also differed between the cell types. Figure 3 preserves this important cell-specific null. Phosphorylated NF-κB p65 did not significantly change in the tested HCAEC experiment. These are mixture findings, not proof that PCA alone suppresses NF-κB at dietary exposure. [Warner et al., 2017, Figures 2–5](https://pmc.ncbi.nlm.nih.gov/articles/PMC5600085/).
