Retinal transketolase activity
Independent biological entity. Read linked claims for experimental scope and context.
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
Benfotiamine increased retinal transketolase activity in diabetic rats.
Experimental context and source evidence
- experimental_model
- High-glucose bovine endothelial cells and diabetic rat retinal experiments.
- exposure
- Pharmacological benfotiamine in high-glucose bovine endothelial cells and diabetic rat retina; not ordinary dietary thiamine.
- limitations
- Pharmacological derivative in bovine endothelial cells/diabetic rats; not proof of human dietary-thiamine benefit or direct NADPH production by transketolase.
- nutrient_topic
- Thiamine research collection; topical membership is not evidence of a direct dietary effect. · Thiamine (vitamin B1)
- organism
- Bos taurus; Rattus norvegicus
- plain_language
- A B1 derivative increased a carbon-transfer enzyme activity in the diabetic retina.
