Across TCGA pan-cancer cohorts, RNU7-80P RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of RNU7-80P’s most consistent transcriptional readouts.
The strongest signal is observed in esophageal carcinoma (ESCA), where RNU7-80P RNA is more highly expressed in tumor relative to normal tissue. In most cancer types RNU7-80P is over-expressed in tumor, although a few such as LUSC show the opposite, repressed pattern.
ESCA and LUSC are the cancer types where RNU7-80P tumor–normal differential expression is most reproducible.
