Outline of Final Research Achievements |
We demonstrated that incretin, such as gastric inhibitory polypeptide and glucagon-like peptide-1, had no effects on the differentiation and mineralization of mesenchymal stem cell-like ST2 cells and osteoblastic MC3T3-E1 cells as well as the expression of RANKL in osteocytic MLO-Y4 cells. Moreover, bone volume and bone strength were not different between C57BL mice with and without administration of a dipeptidyl peptidase-4 (DPP-4) inhibitor. In a clinical study, elevated serum DPP-4 levels were significantly and positively associated with the presence of metabolic syndrome in men with type 2 diabetes. In addition, increased serum DPP-4 levels were significantly associated with the risk of multiple vertebral fractures through bone resorption in the population.
