Across TCGA pan-cancer cohorts, MEIOC mass-spec protein differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of MEIOC’s most consistent transcriptional readouts.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where MEIOC mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types MEIOC is over-expressed in tumor.
PDAC are the cancer types where MEIOC tumor–normal differential expression is most reproducible.
