Across TCGA pan-cancer cohorts, MACROD2-IT1 RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of MACROD2-IT1’s most consistent transcriptional readouts.
The strongest signal is observed in stomach adenocarcinoma (STAD), where MACROD2-IT1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types MACROD2-IT1 is over-expressed in tumor, although a few such as THCA show the opposite, repressed pattern.
STAD, THCA, and LUSC are the cancer types where MACROD2-IT1 tumor–normal differential expression is most reproducible.
