Across TCGA pan-cancer cohorts, HNRNPU mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated HNRNPU data layer compared with 23 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher HNRNPU mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated HNRNPU expression acts as an unfavorable survival marker, although some lineages such as LUAD and PDAC show a favorable association.
HNSC, LUAD, and PDAC are the cancer types where HNRNPU mass-spec protein most reproducibly stratifies survival.
