Across TCGA pan-cancer cohorts, NEDD4 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated NEDD4 data layer compared with 27 for mass-spec protein and 8 for mutation status.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where higher NEDD4 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated NEDD4 expression acts as an unfavorable survival marker, although some lineages such as HNSC show a favorable association.
LSCC, PDAC, and HNSC are the cancer types where NEDD4 mass-spec protein most reproducibly stratifies survival.
