Across TCGA pan-cancer cohorts, RNU6-677P RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of RNU6-677P’s most consistent transcriptional readouts.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where RNU6-677P RNA is more highly expressed in tumor relative to normal tissue. In most cancer types RNU6-677P is over-expressed in tumor.
HNSC and BRCA are the cancer types where RNU6-677P tumor–normal differential expression is most reproducible.
