Across TCGA pan-cancer cohorts, MIR4497 RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of MIR4497’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where MIR4497 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types MIR4497 is over-expressed in tumor, although a few such as KICH show the opposite, repressed pattern.
LUSC, KICH, and LIHC are the cancer types where MIR4497 tumor–normal differential expression is most reproducible.
