Across TCGA pan-cancer cohorts, CTNND2 mass-spec protein differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of CTNND2’s most consistent transcriptional readouts.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where CTNND2 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types CTNND2 is over-expressed in tumor, although a few such as PDAC and LSCC show the opposite, repressed pattern.
PDAC and LSCC are the cancer types where CTNND2 tumor–normal differential expression is most reproducible.
