Across TCGA pan-cancer cohorts, MIR2909 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of MIR2909’s most consistent transcriptional readouts.
The strongest signal is observed in rectum adenocarcinoma (READ), where MIR2909 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types MIR2909 is over-expressed in tumor.
READ, HNSC, and STAD are the cancer types where MIR2909 tumor–normal differential expression is most reproducible.
