Across TCGA pan-cancer cohorts, GPX3 mass-spec protein is linked to patient survival in 7 of 34 cancer types, making it a survival-associated GPX3 data layer compared with 29 for mass-spec protein and 1 for mutation status.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where higher GPX3 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated GPX3 expression acts as an unfavorable survival marker, although some lineages such as PDAC and HNSC show a favorable association.
LSCC, GBM, and PDAC are the cancer types where GPX3 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.
