Across TCGA pan-cancer cohorts, RNU7-43P RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of RNU7-43P’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal papillary cell carcinoma (KIRP), where RNU7-43P RNA is repressed in tumor relative to normal tissue. In most cancer types RNU7-43P is over-expressed in tumor, although a few such as KIRP and LUSC show the opposite, repressed pattern.
KIRP, KICH, and LUSC are the cancer types where RNU7-43P tumor–normal differential expression is most reproducible.
