Across TCGA pan-cancer cohorts, RNU6-943P RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of RNU6-943P’s most consistent transcriptional readouts.
The strongest signal is observed in breast invasive carcinoma (BRCA), where RNU6-943P RNA is repressed in tumor relative to normal tissue. In most cancer types RNU6-943P is over-expressed in tumor, although a few such as BRCA and LUAD show the opposite, repressed pattern.
BRCA, LUAD, and LUSC are the cancer types where RNU6-943P tumor–normal differential expression is most reproducible.
