Across TCGA pan-cancer cohorts, DDR1-DT RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of DDR1-DT’s most consistent transcriptional readouts.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where DDR1-DT RNA is more highly expressed in tumor relative to normal tissue. In most cancer types DDR1-DT is over-expressed in tumor, although a few such as THCA show the opposite, repressed pattern.
HNSC, LUSC, and LIHC are the cancer types where DDR1-DT tumor–normal differential expression is most reproducible.
