Across TCGA pan-cancer cohorts, RNU6-909P RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of RNU6-909P’s most consistent transcriptional readouts.
The strongest signal is observed in lung adenocarcinoma (LUAD), where RNU6-909P RNA is more highly expressed in tumor relative to normal tissue. In most cancer types RNU6-909P is over-expressed in tumor.
LUAD and LIHC are the cancer types where RNU6-909P tumor–normal differential expression is most reproducible.
