Signal transduction in response to DNA damage

Across TCGA patient cohorts, RNA activity of the Signal transduction in response to DNA damage pathway is significantly associated with the RNA expression of multiple genes, with the COAD cohort showing a particularly strong set of associations.

The most reproducible pathway-associated genes across cancer lineages are GALNT13, SLAMF9, and HIKESHIP1, each associated with the pathway in up to 1 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, Signal transduction in response to DNA damage activity versus GALNT13 in COAD (Pearson r = 0.09).

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.

Lineage	Partner gene	X-score	Y-score	p(X)	p(Y)	Sampling consensus	Lineage consensus
COAD	GALNT13 →	-0.349	-1.250	.004	.003	3	1
COAD	SLAMF9 →	-0.680	-1.802	<.001	<.001	3	1
COAD	HIKESHIP1 →	-0.432	-1.366	.001	<.001	3	1
COAD	MEIS1-AS3 →	-0.535	-1.808	<.001	<.001	3	1
