Negative regulation of vascular endothelial growth factor receptor signaling pathway

Across TCGA patient cohorts, RNA activity of the Negative regulation of vascular endothelial growth factor receptor signaling pathway pathway is significantly associated with the protein abundance of multiple proteins, with the UCEC cohort showing a particularly strong set of associations.

The most reproducible pathway-associated proteins across cancer lineages are FAM126A, C1R, and DCN, each associated with the pathway in up to 6 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, Negative regulation of vascular endothelial growth factor receptor signaling pathway activity versus FAM126A in UCEC (Pearson r = 0.44).

Pathway-associated proteins 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.
