PCSK2

Across TCGA pan-cancer cohorts, PCSK2 mass-spec protein is linked to patient survival in 2 of 34 cancer types, making it a survival-associated PCSK2 data layer compared with 20 for mass-spec protein and 12 for mutation status.

The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher PCSK2 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated PCSK2 expression acts as an unfavorable survival marker, although some lineages such as PDAC and LUAD show a favorable association.

PDAC and LUAD are the cancer types where PCSK2 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.
