Across TCGA pan-cancer cohorts, MME-AS1 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of MME-AS1’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal papillary cell carcinoma (KIRP), where MME-AS1 RNA is repressed in tumor relative to normal tissue. In most cancer types MME-AS1 is over-expressed in tumor, although a few such as KIRP and BRCA show the opposite, repressed pattern.
KIRP, BRCA, and LUAD are the cancer types where MME-AS1 tumor–normal differential expression is most reproducible.
