Across TCGA pan-cancer cohorts, MAGEA8-AS1 RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of MAGEA8-AS1’s most consistent transcriptional readouts.
The strongest signal is observed in thyroid carcinoma (THCA), where MAGEA8-AS1 RNA is repressed in tumor relative to normal tissue. In most cancer types MAGEA8-AS1 is over-expressed in tumor, although a few such as THCA and KICH show the opposite, repressed pattern.
THCA, KICH, and LUSC are the cancer types where MAGEA8-AS1 tumor–normal differential expression is most reproducible.
