Response to iron(II) ion

Across TCGA patient cohorts, RNA activity of the Response to iron(II) ion pathway is significantly associated with the RNA expression of multiple genes, with the CCRCC cohort showing a particularly strong set of associations.

The most reproducible pathway-associated genes across cancer lineages are ACTA2-AS1, FAM174B, and LINC02884, each associated with the pathway in up to 4 cancer types. Since the analysis shows associations rather than directional relationships, both pathway-to-partner and partner-to-pathway views are reported.

Each partner is linked to its corresponding Q-omics profile. The scatter plot shows the strongest association, Response to iron(II) ion activity versus ACTA2-AS1 in CCRCC (Pearson r = 0.31).

Pathway-associated genes by consensus

Ranked by combined sampling and lineage consensus. X-score (pathway→partner) and Y-score (partner→pathway) are standardized regression coefficients; both directions are reported because the association is undirected. The reported p-values are derived from the association test.
