Wearing titanium particle-induced osteoclastogenesis, accompanied by peri-implant osteolysis, is the main cause of long-term failure of hip prosthesis. Currently, medications used for the prevention and treatment of peri-implant osteolysis show serious side effects. Therefore, development for more effective new drugs with less side effects is extremely urgent. Vaccarin is a natural flavonoid extracted from Vaccaria segetalis, with various biological functions, including antioxidantory, anti-inflammatory, and promotion of angiogenesis. However, the putative role of vaccarin in the inhibition of titanium particle-induced osteolysis has not been reported. In this study, it was indicated that vaccarin could effectively inhibit RANKL-induced osteoclastogenesis, fusion of F-actin rings, bone resorption, and expression of osteoclast marker genes in a dose-dependent manner in vitro. Moreover, vaccarin could also inhibit RANKL-induced osteoclastogenesis via the inhibition of NF-κB and MAPK (p38, ERK, and JNK) signaling pathways, and inhibit the transcription of downstream transcription factors, such as c-Fos and NFATc1. Consistent with in vitro results, this in vivo study showed that vaccarin exhibited an inhibitory effect on titanium particle-induced osteolysis by antiosteoclastogenesis. In conclusion, vaccarin could be a promising agent for preventing and treating peri-implant osteolysis.
