Across TCGA pan-cancer cohorts, MTRF1 mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated MTRF1 data layer compared with 26 for mass-spec protein and 6 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher MTRF1 mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated MTRF1 expression acts as an unfavorable survival marker, although some lineages such as CCRCC and GBM show a favorable association.
CCRCC, HNSC, and LSCC are the cancer types where MTRF1 mass-spec protein most reproducibly stratifies survival.
