Across TCGA pan-cancer cohorts, HMBOX1-IT1 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of HMBOX1-IT1’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where HMBOX1-IT1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types HMBOX1-IT1 is over-expressed in tumor.
KIRC, STAD, and HNSC are the cancer types where HMBOX1-IT1 tumor–normal differential expression is most reproducible.
