Across TCGA pan-cancer cohorts, ABCB11 mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated ABCB11 data layer compared with 22 for mass-spec protein and 9 for mutation status.
The strongest signal is observed in glioblastoma multiforme (GBM), where higher ABCB11 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated ABCB11 expression acts as an unfavorable survival marker.
GBM are the cancer types where ABCB11 mass-spec protein most reproducibly stratifies survival.
