Across TCGA pan-cancer cohorts, RNU6-823P RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of RNU6-823P’s most consistent transcriptional readouts.
The strongest signal is observed in esophageal carcinoma (ESCA), where RNU6-823P RNA is more highly expressed in tumor relative to normal tissue. In most cancer types RNU6-823P is over-expressed in tumor, although a few such as KIRC show the opposite, repressed pattern.
ESCA, LIHC, and KIRC are the cancer types where RNU6-823P tumor–normal differential expression is most reproducible.
