It was concluded that oxidative DNA damage is increased in patients with Alzheimer's disease and OGG1 Ser326Cys polymorphism may be responsible for this increase.
We performed a case-control study including 178 patients with sporadic AD (sAD) and 146 matched controls to evaluate the role of the Ser326Cys polymorphism as a risk factor for sAD.
The aim of the present study was to validate the association of the five AD-associated variants, 8-oxoguanine DNA glycosylase 1 (<i>OGG1</i>) rs1052133, bridging integrator 1 rs744373, sortilin-related receptor 1, rs1133174, presenilin 2 rs8383, and nerve growth factor rs6330, in the Xinjiang Chinese population.
No significant association was observed between the variant alleles of hOGG1-Ser326Cys (OR=1.32, 95% CI=0.83-2.11), APE1-Asp148Glu (OR=1.08, 95% CI=0.70-1.68), XRCC1-Arg280His (OR=0.53, 95% CI=0.24-1.14) and XRCC1-Arg399Gln (OR=1.05, 95% CI=0.68-1.63) and AD.
The purpose of this study was to determine the level of 8-oxo-2'-deoxyguanosine (8-oxo2dG) and expression of three isoforms of 8-oxoguanine glycosylase 1 (OGG1), OGG1-1a, 1b, and 1c, and OGG1 protein and Ser326Cys and Arg46Gln polymorphisms of the OGG1 gene, in peripheral blood lymphocytes of patients with Alzheimer's disease (AD) and healthy controls.
