Across TCGA pan-cancer cohorts, RNU6-579P RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of RNU6-579P’s most consistent transcriptional readouts.
The strongest signal is observed in kidney chromophobe (KICH), where RNU6-579P RNA is more highly expressed in tumor relative to normal tissue. In most cancer types RNU6-579P is over-expressed in tumor, although a few such as LUSC and KIRC show the opposite, repressed pattern.
KICH, LUSC, and KIRC are the cancer types where RNU6-579P tumor–normal differential expression is most reproducible.
