Across TCGA pan-cancer cohorts, ARNTL mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated ARNTL data layer compared with 25 for mass-spec protein and 7 for mutation status.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher ARNTL mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated ARNTL expression acts as an unfavorable survival marker, although some lineages such as UCEC and CCRCC show a favorable association.
LUAD, UCEC, and CCRCC are the cancer types where ARNTL mass-spec protein most reproducibly stratifies survival.
