Across TCGA pan-cancer cohorts, TECRL RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of TECRL’s most consistent transcriptional readouts.
The strongest signal is observed in thyroid carcinoma (THCA), where TECRL RNA is repressed in tumor relative to normal tissue. In most cancer types TECRL is over-expressed in tumor, although a few such as THCA and HNSC show the opposite, repressed pattern.
THCA, HNSC, and LIHC are the cancer types where TECRL tumor–normal differential expression is most reproducible.
