Across TCGA pan-cancer cohorts, MTCO1P22 RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of MTCO1P22’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where MTCO1P22 RNA is repressed in tumor relative to normal tissue. In most cancer types MTCO1P22 is over-expressed in tumor, although a few such as KIRC and PAAD show the opposite, repressed pattern.
KIRC, KICH, and PAAD are the cancer types where MTCO1P22 tumor–normal differential expression is most reproducible.
