Levels of 8-oxo-dGsn and 8-oxo-Gsn in random urine are consistent with 24 h urine in healthy subjects and patients with renal disease

AbstractOxidatively generated damage to nucleic acids may play an important role in the pathophysiological processes of a variety of diseases. 8-oxo-7,8-dihydro-2′-deoxyguanosine (8-oxo-dGsn) and 8-oxo-7,8-dihydroguanosine (8-oxo-Gsn) are oxidatively generated products of DNA and RNA, respectively. Our previous studies have suggested that the amounts of 8-oxo-dGsn and 8-oxo-Gsn in urine were considerably higher than other body fluid or tissue. The aim of this study was to investigate whether 8-oxo-dGsn and 8-oxo-Gsn levels in random urine samples are consistent with those in 24 h urine samples in healthy subjects and patients with renal disease. A total of 16 healthy subjects and 104 renal disease patients were enrolled in this study, and their random and 24 h urine samples were collected. The levels of urinary 8-oxo-dGsn and 8-oxo-Gsn were quantified by LC-MS/MS and corrected by creatinine. Regardless of healthy subjects or renal disease patients, the levels of oxidised nucleosides in random urine sample...
