Regulation of intrinsic apoptotic signaling pathway in response to DNA damage by p53 class mediator

Across TCGA patient cohorts, RNA activity of the Regulation of intrinsic apoptotic signaling pathway in response to DNA damage by p53 class mediator pathway is significantly associated with the protein abundance of multiple proteins, with the HNSC cohort showing a particularly strong set of associations.

The most reproducible pathway-associated proteins across cancer lineages are ATRX, CDKN2AIP, and MRPL39, 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, Regulation of intrinsic apoptotic signaling pathway in response to DNA damage by p53 class mediator activity versus ATRX in HNSC (Pearson r = 0.26).

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.
