Across TCGA pan-cancer cohorts, MIR6839 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of MIR6839’s most consistent transcriptional readouts.
The strongest signal is observed in breast invasive carcinoma (BRCA), where MIR6839 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types MIR6839 is over-expressed in tumor.
BRCA and LUAD are the cancer types where MIR6839 tumor–normal differential expression is most reproducible.
