It is known that in cancer patients elevated levels of modified nucleosides originated from RNA are excreted in the urine. Modified nucleosides in the serum are thought to be more useful than those in the urine as tumor markers because they are not influenced by other factors. However the determination of these nucleosides is difficult because of their low amounts. To examine the efficacy of the modified nucleosides in the serum as tumor markers, ascites and solid tumor mouse models were prepared, and the amounts of 1-methyladenosine and pseudouridine in the serum were determined. Along with the growth of ascites tumor, the amounts of 1-methyladenosine and pseudouridine in the serum increased. The modified nucleosides in the serum in a solid tumor model also increased. This is the first report on the variation in the amount of 1-methyladenosine in the serum of tumor models, and the results suggest the usefulness of measuring the amounts of 1-methyladenosine and pseudouridine in the serum as tumor markers.
