ATP9B

Across TCGA pan-cancer cohorts, ATP9B mass-spec protein differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of ATP9B’s most consistent transcriptional readouts.

The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where ATP9B mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types ATP9B is over-expressed in tumor, although a few such as PDAC and HNSC show the opposite, repressed pattern.

PDAC, HNSC, and LUAD are the cancer types where ATP9B 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 ATP9B mass-spec protein (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
