NEIL3 and cancer: A recent work in which NEIL1 and NEIL2 (Neil1 −/− /Neil2 −/−) double and NEIL1, NEIL2 and NEIL3 (Neil1 −/− /Neil2 −/− /Neil3 −/−) triple knock-out mouse models have been characterized, no accumulation of oxidative DNA damage, no changes in the mutation frequencies under normal physiological conditions and more importantly, no cancer predisposition for these mice has been observed [25].
