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