Across TCGA pan-cancer cohorts, RERG-AS1 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of RERG-AS1’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal papillary cell carcinoma (KIRP), where RERG-AS1 RNA is repressed in tumor relative to normal tissue. In most cancer types RERG-AS1 is over-expressed in tumor, although a few such as KIRP and UCEC show the opposite, repressed pattern.
KIRP, UCEC, and HNSC are the cancer types where RERG-AS1 tumor–normal differential expression is most reproducible.
