Across TCGA pan-cancer cohorts, SUMO1P2 RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of SUMO1P2’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where SUMO1P2 RNA is repressed in tumor relative to normal tissue. In most cancer types SUMO1P2 is over-expressed in tumor, although a few such as KIRC and KICH show the opposite, repressed pattern.
KIRC, KICH, and KIRP are the cancer types where SUMO1P2 tumor–normal differential expression is most reproducible.
