Across TCGA pan-cancer cohorts, DUX4L45 RNA differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of DUX4L45’s most consistent transcriptional readouts.
The strongest signal is observed in stomach adenocarcinoma (STAD), where DUX4L45 RNA is repressed in tumor relative to normal tissue. In most cancer types DUX4L45 is over-expressed in tumor, although a few such as STAD show the opposite, repressed pattern.
STAD are the cancer types where DUX4L45 tumor–normal differential expression is most reproducible.
