Component
Viability of L929 normal murine fibroblasts
Viability of L929 normal murine fibroblasts. 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)
Treatment of U251 glioma cells with capsaicin and dihydrocapsaicin resulted in a dose- and time-dependent inhibition of cell viability and induction of apoptosis, whereas few effects were observed on the viability of L929 normal murine fibroblast cells, and the apoptosis was associated with generation of reactive oxygen species, increased calcium concentrations, mitochondrial depolarization, release of cytochrome c into the cytosol and activation of caspase-9 and caspase-3, with anti-tumour effects confirmed in a murine tumour xenograft model.
