| Outline of Final Research Achievements |
In this study, we investigated the involvement of sphingosine 1-phosphate (S1P), a potent bioactive lipid mediator, and apolipoprotein M (apoM), a carrier and modulator of S1P, in the pathogenesis of diabetes. We found with animal experimetns that apoM and S1P exert anti-diabetic properties by improving insulin resistance in liver and promoting insulin secretion from beta-cell. We also observed that both plasma and hepatic contents of apoM and S1P are increased in streptozotocin-induced diabetic mice and mice fed with high fat diet. These results suggest the possibility of applying apoM and S1P into clinical laboratory medicine and therapeutic medicine in the fields of diabetes.
