Across TCGA pan-cancer cohorts, RNU6-1234P RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of RNU6-1234P’s most consistent transcriptional readouts.
The strongest signal is observed in esophageal carcinoma (ESCA), where RNU6-1234P RNA is repressed in tumor relative to normal tissue. In most cancer types RNU6-1234P is over-expressed in tumor, although a few such as ESCA and LUSC show the opposite, repressed pattern.
ESCA and LUSC are the cancer types where RNU6-1234P tumor–normal differential expression is most reproducible.
