Across TCGA pan-cancer cohorts, ATF6 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated ATF6 data layer compared with 27 for mass-spec protein and 8 for mutation status.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher ATF6 mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated ATF6 expression acts as an unfavorable survival marker, although some lineages such as LUAD and HNSC show a favorable association.
LUAD, LSCC, and HNSC are the cancer types where ATF6 mass-spec protein most reproducibly stratifies survival.
