Component
HeLa cell viability readout
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
RMDN3 knockdown reduced HeLa cell viability during SLC25A39 silencing.

- limitations
- Selected primary main-text Results and figure legends reviewed; supplementary images not independently inspected. These two papers share authors and are not independent replication. They do not test whether SLC25A39-loss-induced contacts increase HMOX2-dependent iron delivery. ICP-MS measures total iron, not labile iron or transport flux. Contact loss affecting an outcome does not establish that increasing contacts increases it. Ubiquitination/activity readouts do not establish direct enzymatic activation or the outer-membrane iron transport machinery. No clinical or pulmonary-endothelial effect is inferred.
