Across TCGA pan-cancer cohorts, REEP1 mass-spec protein differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of REEP1’s most consistent transcriptional readouts.
The strongest signal is observed in colon adenocarcinoma (COAD), where REEP1 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types REEP1 is over-expressed in tumor, although a few such as COAD and LSCC show the opposite, repressed pattern.
COAD, LSCC, and PDAC are the cancer types where REEP1 tumor–normal differential expression is most reproducible.
