Across TCGA pan-cancer cohorts, MTCO2P22 RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of MTCO2P22’s most consistent transcriptional readouts.
The strongest signal is observed in pancreatic adenocarcinoma (PAAD), where MTCO2P22 RNA is repressed in tumor relative to normal tissue. In most cancer types MTCO2P22 is over-expressed in tumor, although a few such as PAAD and LIHC show the opposite, repressed pattern.
PAAD, KICH, and UCEC are the cancer types where MTCO2P22 tumor–normal differential expression is most reproducible.
