Mouse intestine-specific homeobox protein / Isx
Mouse intestine-specific homeobox protein / Isx. Species, exposure and limitations are retained in each linked claim.
1 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
Lycopene-containing diets increased intestinal ISX expression relative to the vitamin-A-deficient control group.

- experimental_model
- Carotenoid-enzyme knockout comparison and vitamin-A diet experiment

- 1 mg lycopene in cottonseed oil daily for two weeks; separate vitamin-A-deficient versus sufficient diets
- limitations
- Mouse knockout distribution does not directly quantify human cleavage; increased ISX signaling does not prove conversion to vitamin A.
- nutrient_topic
- Lycopene research collection; topical membership is not evidence of a direct dietary effect. · Lycopene
