Across TCGA pan-cancer cohorts, RNU1-65P RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of RNU1-65P’s most consistent transcriptional readouts.
The strongest signal is observed in kidney chromophobe (KICH), where RNU1-65P RNA is repressed in tumor relative to normal tissue. In most cancer types RNU1-65P is over-expressed in tumor, although a few such as KICH show the opposite, repressed pattern.
KICH, UCEC, and LUSC are the cancer types where RNU1-65P tumor–normal differential expression is most reproducible.
