P3H4

Across TCGA pan-cancer cohorts, P3H4 mass-spec protein differs between tumor and matched normal tissue in 6 of 18 cancer types tested, making tumor–normal expression one of P3H4’s most consistent transcriptional readouts.

The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where P3H4 mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types P3H4 is over-expressed in tumor.

HNSC, CCRCC, and LSCC are the cancer types where P3H4 tumor–normal differential expression is most reproducible.

mass-spec protein tumor vs normal associations by lineage

Ranked by sampling consensus. Fold-change is the tumor-versus-normal difference in P3H4 mass-spec protein (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
