Across TCGA pan-cancer cohorts, ERC2-IT1 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of ERC2-IT1’s most consistent transcriptional readouts.
The strongest signal is observed in lung adenocarcinoma (LUAD), where ERC2-IT1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types ERC2-IT1 is over-expressed in tumor, although a few such as THCA show the opposite, repressed pattern.
LUAD and THCA are the cancer types where ERC2-IT1 tumor–normal differential expression is most reproducible.
