Across TCGA pan-cancer cohorts, SEC23A-AS1 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of SEC23A-AS1’s most consistent transcriptional readouts.
The strongest signal is observed in liver hepatocellular carcinoma (LIHC), where SEC23A-AS1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types SEC23A-AS1 is over-expressed in tumor, although a few such as KIRP show the opposite, repressed pattern.
LIHC, KIRP, and PRAD are the cancer types where SEC23A-AS1 tumor–normal differential expression is most reproducible.
