Across TCGA pan-cancer cohorts, KDM3B mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated KDM3B data layer compared with 24 for mass-spec protein and 6 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher KDM3B mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated KDM3B expression acts as an unfavorable survival marker, although some lineages such as CCRCC and GBM show a favorable association.
HNSC, CCRCC, and GBM are the cancer types where KDM3B mass-spec protein most reproducibly stratifies survival.
