Across TCGA pan-cancer cohorts, REV3L-IT1 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of REV3L-IT1’s most consistent transcriptional readouts.
The strongest signal is observed in kidney chromophobe (KICH), where REV3L-IT1 RNA is repressed in tumor relative to normal tissue. In most cancer types REV3L-IT1 is over-expressed in tumor, although a few such as KICH and COAD show the opposite, repressed pattern.
KICH and COAD are the cancer types where REV3L-IT1 tumor–normal differential expression is most reproducible.
