| Outline of Final Research Achievements |
The purpose of this study was to investigate the function of nitrated IL-18 in diabetes, and evaluate as a disease marker. It was found that nitration of IL-18 attenuated sugar metabolism such as STAT3 phosphorylation in gluconeogenesis. Furthermore, nitrated IL-18 was found in the diabetes model mice. These results suggested that nitrated IL-18 maybe involved in the development of diabetes mellitus.
Also, NAD+ was identified as a target molecule of NO. It was found that a function of NAD+ decreased by nitration. It was also found that NO reduced the expression of glycosyltransferase, FUT8, by the induction of DNA methylation. Because NAD+ and oligosaccharide structures are molecules taking the important role in sugar metabolism, these modifications maybe involved in the development of diabetes.
