Across TCGA pan-cancer cohorts, RNU2-3P RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of RNU2-3P’s most consistent transcriptional readouts.
The strongest signal is observed in kidney chromophobe (KICH), where RNU2-3P RNA is repressed in tumor relative to normal tissue. In most cancer types RNU2-3P is over-expressed in tumor, although a few such as KICH and KIRC show the opposite, repressed pattern.
KICH, KIRC, and THCA are the cancer types where RNU2-3P tumor–normal differential expression is most reproducible.
