| Outline of Final Research Achievements |
Epidemiology has revealed that the risk of congenital anomalies is increased in offspring born from mothers with pregestational diabetes. The etiology of such congenital anomalies remains largely unknown, however. In this research, we examined the effect of hyperglycemia on left-right axis formation in mouse embryos, since pregestational diabetes increases the risk of heterotaxia in human. By analyzing streptozotocin-induced diabetic mice and embryos cultured in high glucose medium, we found that high glucose concentration inhibits the establishment of Nodal-Pitx2 expression in left lateral plate mesoderm. Right isomerism in human pregestational diabetes may be explained by this mechanism.
