MPG is a DNA repair enzyme that repairs hypoxanthine, which is formed by spontaneous or oxidative deamination of adenine. MPG also repairs secondary oxidative lesions such as 1,N6-ethenoadenine alkylated bases, and 3-methyladenine and 7-methylguanine.

Phase: Two
QA State: Curated


MPG enzyme activity in peripheral blood mononuclear cells from case patients was higher than in control subjects, which is opposite that of OGG levels in PBMCs. A combined MPG and OGG1 activities score was more strongly associated with lung cancer risk than either activity alone. MPG and OGG1 are being assessed as future members of a panel of biomarkers for lung cancer risk.

Performance Comment

MPG has undergone Phase 2 validation. Work is in progress for Phase 3 validation.
