DEFB1

mass-spec protein & survival
Survivalmass-specKaplan–Meier · TCGA cohorts

Across TCGA pan-cancer cohorts, DEFB1 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated DEFB1 data layer compared with 22 for mass-spec protein and 2 for mutation status.

The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher DEFB1 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated DEFB1 expression acts as an unfavorable survival marker, although some lineages such as UCEC and HNSC show a favorable association.

PDAC, UCEC, and HNSC are the cancer types where DEFB1 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.
