Amentoflavone inhibits debris-induced osteolysis and osteoclastogenesis through blocking MAPK pathway / 实用医学杂志

ABSTRACT

Objective To investigate the effect of amentoflavone(AMF)on inhibiting wear debris-in-duced osteolysis in vivo and RANKL-induced osteoclastogenesis in vitro. Methods Twenty-four male C57BL/J6 mice were randomly divided into four groupsthe control group,titanium group,the low and high concentration group.Micro-CT and histological analysis were performed.CCK-8 assay was used to determin the effect of AMF on the proliferation of BMMs.TRAP staining and bone resorption assays were used to investigate the effect of AMF on osteoclastogenesis and function. The effect of AMF on prevention MAPK signaling was detected by Western blot assay. Results AMF could prevent osteolysis in vivo and suppress osteoclastogenesis,bone resorption without cytotoxicity in vitro.AMF suppressed MAPK signaling pathways.Conclusion AMF could inhibit osteoclastogenesis and titanium debris-induced osteolysis through suppressing MAPK signaling.
