Component
Germ-free rearing or antibiotic treatment
Germ-free rearing or antibiotic treatment. 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.
Where it participates (unsigned role)
GPR43-deficient mice were obese on a normal diet whereas mice overexpressing GPR43 specifically in adipose tissue remained lean even when fed a high-fat diet, and raised under germ-free conditions or after treatment with antibiotics both types of mice had a normal phenotype.

- The germ-free control is what ties the receptor phenotype to microbial short-chain fatty acids rather than to the receptor alone. The receptor senses all short-chain fatty acids, not acetate specifically.
