Across TCGA pan-cancer cohorts, TUT4 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated TUT4 data layer compared with 26 for mass-spec protein and 7 for mutation status.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where higher TUT4 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated TUT4 expression acts as an unfavorable survival marker, although some lineages such as LSCC and CCRCC show a favorable association.
LSCC, CCRCC, and PDAC are the cancer types where TUT4 mass-spec protein most reproducibly stratifies survival.
