RAD18 and acute myeloid leukemia: Conversely, RAD18, which plays a principal role in DNA damage repairment 26; and ARIH2, whose transcription predicts latency of acute myeloid leukemia (AML) 27, tended to be negatively correlated with EYA4 (r = -0.541, P = 0.069 and r = -0.537, P = 0.072), yet such correlation did not reach statistical significance.
