Across TCGA pan-cancer cohorts, ARF1P3 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of ARF1P3’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where ARF1P3 RNA is repressed in tumor relative to normal tissue. In most cancer types ARF1P3 is over-expressed in tumor, although a few such as KIRC and KICH show the opposite, repressed pattern.
KIRC, KICH, and THCA are the cancer types where ARF1P3 tumor–normal differential expression is most reproducible.
