Abstract

Bergenin, an active component of plants in the genus Bergenia, has multiple biological activities, including anti-inflammatory and immunomodulatory properties. We investigated the effects of bergenin on MC3T3-E1 osteoblasts. Bergenin treatment significantly elevated collagen synthesis, alkaline phosphatase activity, osteocalcin synthesis, and mineralization in the cells (p < 0.05). Additionally, bergenin increased the ratio of osteoprotegerin to receptor activator of nuclear factor kappa-B ligand, and cyclophilin B release. Methylglyoxal (MG), a highly reactive dicarbonyl compound, is the major precursor in the formation of advanced glycation end products. Pretreatment of MC3T3-E1 cells with bergenin prevented MG-induced cell death. Furthermore, bergenin treatment significantly reduced the induction of activating transcription factor 6 and autophagy by MG. These results indicate that bergenin may have positive effects on critical osteoblastic cell functions.
