Across TCGA pan-cancer cohorts, HAO2-IT1 RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of HAO2-IT1’s most consistent transcriptional readouts.
The strongest signal is observed in liver hepatocellular carcinoma (LIHC), where HAO2-IT1 RNA is repressed in tumor relative to normal tissue. In most cancer types HAO2-IT1 is over-expressed in tumor, although a few such as LIHC and KIRP show the opposite, repressed pattern.
LIHC, KIRP, and CHOL are the cancer types where HAO2-IT1 tumor–normal differential expression is most reproducible.
