The association between the APE1 Asp148Glu polymorphism and prostate cancer susceptibility: a meta-analysis based on case-control studies

The apurinic/apyrimidinic endonuclease 1 (APE1) plays important roles in the repair of DNA damage and adducts. However, previous case-control studies on the association between the APE1 Asp148Glu polymorphism and prostate cancer susceptibility have shown contradictory results, this meta-analysis was performed to draw a more precise estimation of the relationship. A total of seven case-control studies including 1,294 cases and 1,762 controls were included for analysis. In overall, no significant associations were found in all genetic models (GG vs. TT: OR = 1.16, 95 % CI 0.89-1.52; TG vs. TT: OR = 1.04, 95 % CI 0.81-1.35; the dominant model GG + TG vs. TT: OR = 1.12, 95 % CI 0.96-1.30; the recessive model GG vs. TG + TT: OR = 0.90, 95 % CI 0.77-1.04); in the subgroup by source of control, we found a significant association for the dominant model in Hospital-based subgroup (OR = 1.34, 95 % CI 1.08-1.68), no significant associations were found in other models in the subgroups. This meta-analysis suggested that the APE1 Asp148Glu polymorphism was a risk factor for prostate cancer susceptibility in Hospital-based population.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000348923900022&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Biochemistry & Molecular BiologyGenetics & HereditySCI(E)3ARTICLEningwang1978@163.com; yajiewa0459@163.com; chuanliu2005@163.com1281-28829
