Investigation of the effect of hydroalcoholic mumie extract on expression of osteoprotegerin (OPG) and receptor activator of nuclear factor kappa-B ligand (RANKL)

Background and Aim: Osteoporosis is one of the most common bone diseases that is caused by an imbalance between the activity of osteoblasts and osteoclasts. Osteoprotegerin (OPG) plays an active role in inhibiting osteoclasts by binding to the receptor activator of nuclear factor kappa-B ligand (RANKL). The balance in the OPG/RANKL ratio is important in bone remodeling. The current study investigated and compared the effects of mumie extract and chemical drugs on cell proliferation, expression of OPG and RANKL in MG63 cells.
