Across TCGA pan-cancer cohorts, RNU6-118P RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of RNU6-118P’s most consistent transcriptional readouts.
The strongest signal is observed in thyroid carcinoma (THCA), where RNU6-118P RNA is repressed in tumor relative to normal tissue. In most cancer types RNU6-118P is over-expressed in tumor, although a few such as THCA show the opposite, repressed pattern.
THCA, HNSC, and LIHC are the cancer types where RNU6-118P tumor–normal differential expression is most reproducible.
