ABCB5

Across TCGA pan-cancer cohorts, ABCB5 mass-spec protein differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of ABCB5’s most consistent transcriptional readouts.

The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where ABCB5 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types ABCB5 is over-expressed in tumor, although a few such as PDAC and CCRCC show the opposite, repressed pattern.

PDAC and CCRCC are the cancer types where ABCB5 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 ABCB5 mass-spec protein (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
