Across TCGA pan-cancer cohorts, NRG1-IT1 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of NRG1-IT1’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where NRG1-IT1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types NRG1-IT1 is over-expressed in tumor.
LUSC and LIHC are the cancer types where NRG1-IT1 tumor–normal differential expression is most reproducible.
