Across TCGA pan-cancer cohorts, RNU5B-4P RNA differs between tumor and matched normal tissue in 14 of 18 cancer types tested, making tumor–normal expression one of RNU5B-4P’s most consistent transcriptional readouts.
The strongest signal is observed in lung adenocarcinoma (LUAD), where RNU5B-4P RNA is repressed in tumor relative to normal tissue. In most cancer types RNU5B-4P is over-expressed in tumor, although a few such as LUAD and KIRP show the opposite, repressed pattern.
LUAD, KIRC, and KIRP are the cancer types where RNU5B-4P tumor–normal differential expression is most reproducible.
RNA tumor vs normal associations by lineage
Ranked by sampling consensus. Fold-change is the tumor-versus-normal difference in RNU5B-4P RNA (log2); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
