Across TCGA pan-cancer cohorts, RNA activity of the Formation of quadruple SL/U4/U5/U6 snRNP pathway is associated with patient survival in 17 of 34 cancer lineages. Pathway activity is summarized from the expression of its 10 member genes.
The strongest signal is observed in colon adenocarcinoma (COAD), where higher Formation of quadruple SL/U4/U5/U6 snRNP pathway activity is associated with better disease-free survival. In most high-consensus cancer types, elevated pathway activity shows an unfavorable survival association, although some cancer types, such as COAD and LIHC, show the opposite pattern, with higher activity associated with better survival.
COAD, ESCA, and LIHC are the cancer lineages in which this pathway most reproducibly stratifies patient survival.
Pathway-activity survival associations by lineage
Ranked by sampling consensus. AUC1 and AUC2 represent the survival AUCs for the high- and low-pathway-activity groups, respectively. The group with the lower AUC is interpreted as having poorer survival. The reported p-values are derived from the log-rank test.
