Component
Nitric oxide release by human endothelial cells
Nitric oxide release by human endothelial cells. Interpret through the linked experimental species, preparation, compartment and exposure; no universal causal effect is implied.
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 acts on it
C3G pretreatment improved NO release in palmitate-challenged human endothelial cells.

**Nrf2 dependence has been tested, but is context-specific.** C3G pretreatment in palmitate-challenged human endothelial cells improved IRS-1/PI3K/Akt-related insulin signaling and restored eNOS expression and NO release. Nrf2 silencing impaired the protective response. This is stronger than merely observing an antioxidant-gene increase, but neither direct KEAP1 binding nor the same action of circulating conjugates follows. The source's exact exposure protocol must accompany any quantitative reuse; only its accessible abstract was extracted here. [Fratantonio et al., 2017](https://pubmed.ncbi.nlm.nih.gov/28011403/).
