Across TCGA pan-cancer cohorts, RNU7-55P RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of RNU7-55P’s most consistent transcriptional readouts.
The strongest signal is observed in stomach adenocarcinoma (STAD), where RNU7-55P RNA is more highly expressed in tumor relative to normal tissue. In most cancer types RNU7-55P is over-expressed in tumor.
STAD and KIRC are the cancer types where RNU7-55P tumor–normal differential expression is most reproducible.
