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