Across TCGA pan-cancer cohorts, SUMO2P18 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of SUMO2P18’s most consistent transcriptional readouts.
The strongest signal is observed in thyroid carcinoma (THCA), where SUMO2P18 RNA is repressed in tumor relative to normal tissue. In most cancer types SUMO2P18 is over-expressed in tumor, although a few such as THCA and BRCA show the opposite, repressed pattern.
THCA, BRCA, and ESCA are the cancer types where SUMO2P18 tumor–normal differential expression is most reproducible.
