Across TCGA pan-cancer cohorts, CELSR1 mass-spec protein differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of CELSR1’s most consistent transcriptional readouts.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where CELSR1 mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types CELSR1 is over-expressed in tumor, although a few such as CCRCC and LUAD show the opposite, repressed pattern.
PDAC, CCRCC, and LSCC are the cancer types where CELSR1 tumor–normal differential expression is most reproducible.
