Across TCGA pan-cancer cohorts, MIR4451 RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of MIR4451’s most consistent transcriptional readouts.
The strongest signal is observed in esophageal carcinoma (ESCA), where MIR4451 RNA is repressed in tumor relative to normal tissue. In most cancer types MIR4451 is over-expressed in tumor, although a few such as ESCA and PAAD show the opposite, repressed pattern.
ESCA, PAAD, and STAD are the cancer types where MIR4451 tumor–normal differential expression is most reproducible.
