Across TCGA pan-cancer cohorts, MIR4757 RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of MIR4757’s most consistent transcriptional readouts.
The strongest signal is observed in breast invasive carcinoma (BRCA), where MIR4757 RNA is repressed in tumor relative to normal tissue. In most cancer types MIR4757 is over-expressed in tumor, although a few such as BRCA and HNSC show the opposite, repressed pattern.
BRCA, HNSC, and THCA are the cancer types where MIR4757 tumor–normal differential expression is most reproducible.
