Across TCGA pan-cancer cohorts, RNU4-60P RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of RNU4-60P’s most consistent transcriptional readouts.
The strongest signal is observed in stomach adenocarcinoma (STAD), where RNU4-60P RNA is more highly expressed in tumor relative to normal tissue. In most cancer types RNU4-60P is over-expressed in tumor, although a few such as ESCA show the opposite, repressed pattern.
STAD, LUSC, and ESCA are the cancer types where RNU4-60P tumor–normal differential expression is most reproducible.
