Across TCGA pan-cancer cohorts, RPL21P50 RNA differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of RPL21P50’s most consistent transcriptional readouts.
The strongest signal is observed in esophageal carcinoma (ESCA), where RPL21P50 RNA is repressed in tumor relative to normal tissue. In most cancer types RPL21P50 is over-expressed in tumor, although a few such as ESCA show the opposite, repressed pattern.
ESCA are the cancer types where RPL21P50 tumor–normal differential expression is most reproducible.
