Across TCGA pan-cancer cohorts, MIR6833 RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of MIR6833’s most consistent transcriptional readouts.
The strongest signal is observed in colon adenocarcinoma (COAD), where MIR6833 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types MIR6833 is over-expressed in tumor, although a few such as KICH and THCA show the opposite, repressed pattern.
COAD, KICH, and PRAD are the cancer types where MIR6833 tumor–normal differential expression is most reproducible.
