| pubmed-article:12899941 | pubmed:abstractText | The putative modulation of the base excision repair enzyme, human 8-oxoguanine glycosylase (hOGG1), important in the removal of the potentially mutagenic lesion 8-oxo-2'-deoxyguanosine (8-oxodG), was investigated in human cell culture models. The expression of specific mRNA and protein was measured following pro-oxidant and antioxidant treatments in one human lymphoblastoid and one keratinocyte line. The measurement of intracellular reactive oxygen species generation was monitored by a fluorogenic assay and potential genotoxic effects confirmed by the dose-dependent increase in formamidopyrimidine-DNA glycosylase (Fpg) sensitive sites by alkaline unwinding following sub-lethal doses of hydrogen peroxide. The generation of a potentially antioxidant environment was assessed by the intracellular increase and extracellular depletion in ascorbic acid, confirmed by capillary electrophoresis. Despite these pro-oxidant and antioxidant treatments no significant change in mRNA of hOGG1 was observed in either cell line. Western analysis revealed that relatively high, yet noncytotoxic, doses of hydrogen peroxide caused a consistent approximate 50% decrease in hOGG1 protein in lymphoblastoid cells. The lack of upregulation of hOGG1 suggests the gene is constitutively expressed, which is further supported by studies examining the sequence of its promoter region. However, hOGG1 protein turnover may be sensitive to intracellular redox changes. | lld:pubmed |
