Across TCGA pan-cancer cohorts, HDAC3 mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated HDAC3 data layer compared with 25 for mass-spec protein and 5 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher HDAC3 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated HDAC3 expression acts as an unfavorable survival marker, although some lineages such as LSCC show a favorable association.
HNSC, LSCC, and CCRCC are the cancer types where HDAC3 mass-spec protein most reproducibly stratifies survival.
