Across TCGA pan-cancer cohorts, MIR4803 RNA differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of MIR4803’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where MIR4803 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types MIR4803 is over-expressed in tumor.
LUSC are the cancer types where MIR4803 tumor–normal differential expression is most reproducible.
