Research Abstract |
To clarify the molecular based relationship of osteoarthritis (OA) and diabetes mellitus (DM), we evaluated accumulations of advanced glycation end products (AGEs) in joint tissues. DM rats showed similar AGE accumulations and the expression of mRNA and proteins related with OA on both cartilage and synovium compared with normal rats. There was also no difference of AGE accumulations among cultured chondrocytes treated with various concentrations of glucose. Moreover, susceptibility of OA induced by knee ligament resection was similar between DM and normal rats. These results indicate indistinguishable associations with OA and DM from the point of view of AGEs.
