MALDI-TOF MS analysis of urinary nucleosides [PDF]

Journal of the American Society for Mass Spectrometry, 2005
As RNA turnover seems to be impaired in cancer patients, modified nucleosides have been evaluated as potential tumor markers. Modified nucleosides are mainly formed post-transcriptionally in tRNA, set free during RNA metabolism, and excreted in urine.
