Across TCGA pan-cancer cohorts, RNU6-452P RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of RNU6-452P’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where RNU6-452P RNA is repressed in tumor relative to normal tissue. In most cancer types RNU6-452P is over-expressed in tumor, although a few such as KIRC and THCA show the opposite, repressed pattern.
KIRC and THCA are the cancer types where RNU6-452P tumor–normal differential expression is most reproducible.
