Across TCGA pan-cancer cohorts, MAD2L1BP mass-spec protein differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of MAD2L1BP’s most consistent transcriptional readouts.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where MAD2L1BP mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types MAD2L1BP is over-expressed in tumor, although a few such as HNSC show the opposite, repressed pattern.
CCRCC, COAD, and HNSC are the cancer types where MAD2L1BP tumor–normal differential expression is most reproducible.
