Outline of Final Research Achievements

We demonstrated that the increase of triglyceride accumulation and the decrease of GPR40 gene expression in the pancreas of genetically obese rats deficient in leption receptor gene.We created GPR40 KO rat and now investigate the abnormalities in glucose and lipid metabolism.We established leptin gene deficient rats as a new genetically obese animal model.We succeeded in differentiation of human iPS cells into adipocyte for the first time in the world. We also established iPS cell lines from congenital lipodystrophy patients, and established a tool for the elucidation of pathogenesis and pathophysiology.
