摘要： Inflammatory bowel disease is linked to a higher occurrence of bone loss. Oxyberberine can effectively improve experimental inflammatory bowel disease. However, no study has shown the effect of oxyberberine on inflammatory bowel disease induced bone loss. The present study was performed to investigate the role of oxyberberine in inflammatory bowel disease induced osteoporosis in chronic inflammatory bowel disease mice model. The inflammatory bowel disease mice were orally given two doses of oxyberberine daily. Blood, colon, and bone specimens were collected for biomarker assessments and histological examinations. Bone biomechanical properties and key proteins and genes involved in the receptor activator of nuclear factor kappa-B ligand/nuclear factor kappa-B signaling pathway were evaluated. Additionally, the binding characteristics of oxyberberine and receptor activator of nuclear factor kappa-B ligand were evaluated by in silico simulation. Results indicated that oxyberberine treatment significantly attenuated the macroscopic damage, colonic shortening, and histological injury from the colon. Furthermore, oxyberberine decreased serum inflammatory cytokine levels. The intervention with oxyberberine significantly mitigated the deterioration of bone mass, biomechanical properties, and microstructural parameters. Moreover, the upregulated osteoclast formation factors in model mice were significantly abolished by oxyberberine. In silico simulation results also showed that oxyberberine was firmly bound with target protein. Hence, our findings indicated that oxyberberine had the potential to mitigate inflammatory bowel disease induced inflammation in bone, inhibit osteoclast formation through regulating the receptor activator of nuclear factor kappa-B ligand/nuclear factor kappa-B signaling pathway, and might be a valuable approach in preventing bone loss associated with inflammatory bowel disease.
