Across TCGA pan-cancer cohorts, MIR4254 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of MIR4254’s most consistent transcriptional readouts.
The strongest signal is observed in breast invasive carcinoma (BRCA), where MIR4254 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types MIR4254 is over-expressed in tumor.
BRCA and LUSC are the cancer types where MIR4254 tumor–normal differential expression is most reproducible.
