GO:0014047Ontology (GO BP)GO biological process · ~28 member genes
Q-omics provides the Glutamate secretion (GO:0014047) pathway profile, scoring each patient from the combined activity of its roughly 28 member genes. Pathway activity is associated with patient survival in 23 of 34 cancer types, with the highest sampling consensus in LGG. Among the 18 cancer types available for tumor–normal comparison, the pathway is differentially active in 7, with the highest sampling consensus in BRCA. Additionally, pathway RNA activity shows 30,001 significant cross-omics associations, again with the highest sampling consensus in BRCA. Together, these results highlight LGG, and BRCA 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 Glutamate secretion survival associations by molecular data type. RNA-level pathway activity shows survival associations in the most cancer types (23). 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 Glutamate secretion activity shows favorable associations in LGG and ACC, but unfavorable associations in UCEC, STAD, KIRC and SCLC. In the LGG Kaplan–Meier curve the low-activity group declines faster, consistent with the favorable association (log-rank p < 0.001). LGG ranks highest by sampling consensus for Glutamate secretion.
This table summarizes Glutamate secretion tumor–normal activity differences by data type. RNA-level activity shows significant tumor–normal differences in 7 cancer types, while mass-spec protein activity shows differences in 4. The strongest signals are in BRCA for RNA and COAD for protein.
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 and lower tumor activity in BRCA, UCEC, THCA, LUAD and KICH. In the BRCA box plot, normal samples show higher pathway activity than tumor samples (log2 FC = −0.081, t-test p < 0.001).
This table shows molecular features associated with Glutamate secretion 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 BRCA. In cancer cell lines, RNA-expression features and functional dependencies dominate, with the largest set in LIVER.
