Outline of Final Research Achievements

ATP(Adenosine tri-phosphate), one of ribonucleic acids, acts as an intra-cellular energy transfer. ATP is also used as a substrate to synthesize messenger RNA and as a ligand of inter-celular signaling. Damaged ATP produced by synchrotron soft X-rays might act as down- or up-regulation of these biological function. In this study, we examined the relation between molecular damage of ATP and its biological activity using various biological assesments, such as energy donor activity, genetic information transfer, adn inter-cellular signaling activity. The obtained results suggest that the altered ATP molecule might contribute the induction of changing of a radiation sensitivity of cancer cells.
