Across TCGA pan-cancer cohorts, ITPKB-AS1 RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of ITPKB-AS1’s most consistent transcriptional readouts.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where ITPKB-AS1 RNA is repressed in tumor relative to normal tissue. In most cancer types ITPKB-AS1 is over-expressed in tumor, although a few such as UCEC and READ show the opposite, repressed pattern.
UCEC, READ, and COAD are the cancer types where ITPKB-AS1 tumor–normal differential expression is most reproducible.
