Across TCGA pan-cancer cohorts, MIR4486 RNA differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of MIR4486’s most consistent transcriptional readouts.
The strongest signal is observed in thyroid carcinoma (THCA), where MIR4486 RNA is repressed in tumor relative to normal tissue. In most cancer types MIR4486 is over-expressed in tumor, although a few such as THCA show the opposite, repressed pattern.
THCA are the cancer types where MIR4486 tumor–normal differential expression is most reproducible.
