原始语种摘要: Abstract(#br)GPX1 encoding the enzyme glutathione peroxidase 1 (GPX1) and h OGG1 encoding the 8-oxoguanine glycosylase 1 (OGG1) may counteract oxidative stress and resulting DNA damage associated with lifestyle-related exposures. We examined whether the polymorphisms GPX1 Pro 198 Leu and OGG1 Ser 326 Cys or low erythrocyte GPX enzyme activity in pre-diagnostic blood samples are associated with colorectal cancer risk, and assessed possible interactions between the polymorphisms or enzyme activity and various lifestyle factors in relation to colorectal cancer risk. Additionally, we studied whether the GPX1 Pro 198 Leu polymorphism and several lifestyle factors predict GPX activity in erythrocytes. The present study was nested within the prospective “Diet, Cancer and Health” study of 57,053...
