Across TCGA pan-cancer cohorts, SLC1A1 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated SLC1A1 data layer compared with 27 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher SLC1A1 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated SLC1A1 expression acts as an unfavorable survival marker, although some lineages such as CCRCC and GBM show a favorable association.
LUAD, CCRCC, and GBM are the cancer types where SLC1A1 mass-spec protein most reproducibly stratifies survival.
