PIGB

Across TCGA pan-cancer cohorts, PIGB mass-spec protein differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of PIGB’s most consistent transcriptional readouts.

The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where PIGB mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types PIGB is over-expressed in tumor, although a few such as HNSC and PDAC show the opposite, repressed pattern.

HNSC, PDAC, and LSCC are the cancer types where PIGB 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 PIGB mass-spec protein (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
