Across TCGA pan-cancer cohorts, RNU6-550P RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of RNU6-550P’s most consistent transcriptional readouts.
The strongest signal is observed in thyroid carcinoma (THCA), where RNU6-550P RNA is repressed in tumor relative to normal tissue. In most cancer types RNU6-550P is over-expressed in tumor, although a few such as THCA and KIRP show the opposite, repressed pattern.
THCA and KIRP are the cancer types where RNU6-550P tumor–normal differential expression is most reproducible.
