Across TCGA pan-cancer cohorts, MT-TA RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of MT-TA’s most consistent transcriptional readouts.

The strongest signal is observed in colon adenocarcinoma (COAD), where MT-TA RNA is repressed in tumor relative to normal tissue. In most cancer types MT-TA is over-expressed in tumor, although a few such as COAD and ESCA show the opposite, repressed pattern.

COAD, ESCA, and KICH are the cancer types where MT-TA tumor–normal differential expression is most reproducible.

RNA tumor vs normal associations by lineage

Ranked by sampling consensus. Fold-change is the tumor-versus-normal difference in MT-TA RNA (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
