Muscle hypertrophy in response to stress

Across TCGA patient cohorts, RNA activity of the Muscle hypertrophy in response to stress pathway is significantly associated with the protein abundance of multiple proteins, with the PDAC cohort showing a particularly strong set of associations.

The most reproducible pathway-associated proteins across cancer lineages are SEPTIN4, KANK2_S323, and SEPTIN7, each associated with the pathway in up to 8 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, Muscle hypertrophy in response to stress activity versus SEPTIN4 in PDAC (Pearson r = 0.12).

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.
