Across TCGA pan-cancer cohorts, RNU6-178P RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of RNU6-178P’s most consistent transcriptional readouts.
The strongest signal is observed in thyroid carcinoma (THCA), where RNU6-178P RNA is repressed in tumor relative to normal tissue. In most cancer types RNU6-178P is over-expressed in tumor, although a few such as THCA and KICH show the opposite, repressed pattern.
THCA, PRAD, and CHOL are the cancer types where RNU6-178P tumor–normal differential expression is most reproducible.
