Component
Mouse Nrf2 / Nfe2l2
Mouse Nrf2 / Nfe2l2. Species, exposure and limitations are retained in each linked claim.
22 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 it acts on
Nrf2 activation increased E2F1 mRNA in the regeneration model.

## astaxanthin-retina-high-glucose Blocking stress-response signaling removed protection in the retinal-cell model. Astaxanthin reduced ROS and apoptosis in high-glucose-challenged mouse 661W cells; PI3K or Nrf2 inhibition abolished the protective effect. Model: Mouse photoreceptor-derived 661W cells and pharmacological inhibitors. Limitations: Not a human diabetic-retinopathy trial; inhibitor experiments do not establish unique direct molecular targets.
