DDB2

Across TCGA pan-cancer cohorts, DDB2 mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated DDB2 data layer compared with 26 for mass-spec protein and 3 for mutation status.

The strongest signal is observed in lung adenocarcinoma (LUAD), where higher DDB2 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated DDB2 expression acts as an unfavorable survival marker, although some lineages such as PDAC and LSCC show a favorable association.

LUAD, PDAC, and LSCC are the cancer types where DDB2 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.
