Across TCGA pan-cancer cohorts, MT-ND4 mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated MT-ND4 data layer compared with 23 for mass-spec protein.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher MT-ND4 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated MT-ND4 expression acts as an unfavorable survival marker, although some lineages such as CCRCC and HNSC show a favorable association.
LUAD, CCRCC, and UCEC are the cancer types where MT-ND4 mass-spec protein most reproducibly stratifies survival.
mass-spec protein survival associations by lineage
Ranked by sampling consensus. AUC1 and AUC2 indicate survival in the high- and low-expression groups, respectively; the lower AUC marks the poorer-surviving group. p-values are from the log-rank test.
