Across TCGA pan-cancer cohorts, RNU6-808P RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of RNU6-808P’s most consistent transcriptional readouts.
The strongest signal is observed in kidney chromophobe (KICH), where RNU6-808P RNA is repressed in tumor relative to normal tissue. In most cancer types RNU6-808P is over-expressed in tumor, although a few such as KICH and THCA show the opposite, repressed pattern.
KICH, HNSC, and CHOL are the cancer types where RNU6-808P tumor–normal differential expression is most reproducible.
