PDXK

Across TCGA pan-cancer cohorts, PDXK mass-spec protein differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of PDXK’s most consistent transcriptional readouts.

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

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