Abstract:
Objective:To study the effects of deoxyadenosine(dAdo) on methotrexate (MTX) induced suppression of inflammatory bone destruction.Methods:The culture system of whole bone marrow cells (WBMCs) was utilized to evaluate osteoclastogenesis.TRAP staining and μCT analysis were utilized to evaluate osteoclastogenesis and bone destruction in adjuvant arthritis rats.Results:In the bone marrow culture system,MTX-induced suppression of osteoclastogenesis was abrogated by the addition of dAdo.dAdo canceled MTX-induced suppression of osteoclastogenesis in the rats with arthritis,and significantly abolished the therapeutic effects of MTX on inflammatory bone destruction in the rats.Conclusion:The accumulation of dAdo may be one cause of the losing effectiveness of MTX in bone destruction.
