Component
Rat cecal shikimate accumulation
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
The 90-day glyphosate study recorded cecal shikimate accumulation consistent with pathway inhibition.

- Primary full text retrieved; relevant methods/results/figures reviewed. Selective extraction, not raw-data reanalysis or exhaustive supplemental extraction.
- experimental_model
- Female Sprague–Dawley rats; 0.5, 50 and 175 mg/kg/day glyphosate-equivalent groups; 12/group.

- limitations
- Study-level direction; no unsupported per-dose significance claim. Pool accumulation is not increased downstream flux.

**An upstream pool can rise when flux is blocked.** Mesnage 2021 compared pure glyphosate and Roundup MON52276 in female Sprague–Dawley rats for 90 days at 0.5, 50 and 175 mg/kg/day glyphosate-equivalent exposures, with 12 animals per group. Cecal shikimate and DHS accumulation supported pathway inhibition; abundance alone was less informative. The collection records study-level accumulation rather than asserting every dose had an identical significant effect. Overall alpha-diversity differences were not significant (p=0.09), while beta diversity differed. Selected low-abundance taxa changed, and formulation-specific differences remained. Serum shikimate was undetected with the employed method, whose sensitivity and protein interference limit a zero-exposure interpretation.
