Outline of Final Research Achievements |
We previously identified a novel secretary Semaphorin, Semaphorin3G (Sema3G), that is expressed in vascular endothelial cells. We then evaluated the roles of Sema3G in gut microbiota and its implication in pathogenesis of the life-style related diseases including obesity and fatty liver disease. Metagenome analysis showed that Sema3G KO gut microbiota included more Bcteroides and less Firmicutes. In addition, Sema3G KO showed more Cyanobacteria and less Verrucomicrobia. Metabolic analysis revealed that Sema3G KO mice showed better glucose tolerance, better insulin sensitivity, and the fatty liver was less severe compared to wild type mice after high fat diet.
