Across TCGA pan-cancer cohorts, CREB3L2-AS1 RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of CREB3L2-AS1’s most consistent transcriptional readouts.
The strongest signal is observed in kidney chromophobe (KICH), where CREB3L2-AS1 RNA is repressed in tumor relative to normal tissue. In most cancer types CREB3L2-AS1 is over-expressed in tumor, although a few such as KICH and BRCA show the opposite, repressed pattern.
KICH, LIHC, and BRCA are the cancer types where CREB3L2-AS1 tumor–normal differential expression is most reproducible.
