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.

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.

    **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.
