Analysis, identification and determination of urinary modified nucleosides of cancer and AIDS patients.
Modified nucleoside levels in urine samples collected before and after surgery from seven patients with malignant gastrointestinal cancer were examined by the reversed-phase HPLC method. Those of an AIDS patient, a breast cancer patient, and pooled normal urines were also compared. To monitor the effects of therapy on cancer patients, the levels of modified nucleosides, especially t6A and MTA, were found to be fairly effective. In an AIDS patient, the levels of most of the nucleosides exhibited remarkable increases compared to normal urine.
