Across TCGA pan-cancer cohorts, NPAS1 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated NPAS1 data layer compared with 21 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher NPAS1 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated NPAS1 expression acts as an unfavorable survival marker.
HNSC, PDAC, and LSCC are the cancer types where NPAS1 mass-spec protein most reproducibly stratifies survival.
