Across TCGA pan-cancer cohorts, RNU6-1291P RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of RNU6-1291P’s most consistent transcriptional readouts.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where RNU6-1291P RNA is repressed in tumor relative to normal tissue. In most cancer types RNU6-1291P is over-expressed in tumor, although a few such as UCEC show the opposite, repressed pattern.
UCEC and LUSC are the cancer types where RNU6-1291P tumor–normal differential expression is most reproducible.
