GO:0007266Ontology (GO BP)GO biological process · ~137 member genes
Q-omics provides the Rho protein signal transduction (GO:0007266) pathway profile, scoring each patient from the combined activity of its roughly 137 member genes. Pathway activity is associated with patient survival in 20 of 34 cancer types, with the highest sampling consensus in ACC. Among the 18 cancer types available for tumor–normal comparison, the pathway is differentially active in 10, with the highest sampling consensus in HNSC. Additionally, pathway RNA activity shows 36,742 significant cross-omics associations, again with the highest sampling consensus in STAD. Together, these results highlight ACC, HNSC, and STAD as cancer lineages where the pathway shows reproducible signals across outcome, tissue activity, and molecular association analyses.
Every result is evaluated using two consensus scores. Sampling consensus measures how consistently a finding is reproduced within a cancer lineage across different conditions. Lineage consensus measures how broadly the result is shared across cancer types, distinguishing pan-cancer signals from lineage-specific patterns. Pathway-against-pathway and pathway-against-mutation comparisons are not available for ontology entities.
Survival associations
This table summarizes Rho protein signal transduction survival associations by molecular data type. RNA-level pathway activity shows survival associations in the most cancer types (20). The rightmost column indicates the cancer type with the highest sampling consensus for each layer.
This table ranks reproducible pathway activity–survival associations across cancer types. High Rho protein signal transduction activity shows favorable associations in HNSC and LUAD, but unfavorable associations in ACC, LGG, KIRP and COAD. In the ACC Kaplan–Meier curve the high-activity group declines faster, consistent with the unfavorable association (log-rank p < 0.001). ACC ranks highest by sampling consensus for Rho protein signal transduction.
This table summarizes Rho protein signal transduction tumor–normal activity differences by data type. RNA-level activity shows significant tumor–normal differences in 10 cancer types. The strongest signals are in KIRC for RNA.
This table ranks reproducible tumor–normal activity differences for the pathway. A positive fold-change indicates higher activity in tumor tissue. The pathway shows higher tumor activity across HNSC, KIRC and LIHC and lower tumor activity in KICH, LUSC and BRCA. In the HNSC box plot, tumor samples show higher pathway activity than matched normal samples (log2 FC = +0.034, t-test p < 0.001).
This table shows molecular features associated with Rho protein signal transduction pathway activity in patient tissues and cancer cell lines. In patient samples, pathway activity is most strongly linked to RNA and protein features, with the largest associated set in STAD. In cancer cell lines, RNA-expression features and functional dependencies dominate, with the largest set in LUNG_SCLC.
