Abstract:
Aim To investigate the effects of combined administration of loganin and berberine on bone structure and metabolism in diabetic mice and its potential mechanism.Methods The diabetic ICR mouse model was induced by high fat diet(HFD).After 10 weeks of combined intervention, the effects of loganin and berberine on body weight, body fat rate, blood glucose, blood lipid and serum oxidative stress levels were observed.Bone microstructure was scanned by micro-CT.Biomechanical characteristics of bone were measured by three-point bending test, and material properties were detected by fourier transform infrared(FTIR).The pathological changes were observed by HE and TRAP staining.Protein expressions involved in advanced glycation end products(AGEs)and their receptors(RAGE)/nuclear factor-κB(NF-κB)signaling pathway were detected by immunohistochemistry.Results The combined administration of loganin and berberine could significantly inhibit the weight gain, reduce the levels of blood glucose, blood lipid and oxidative stress, as well as improve glucose tolerance.In addition, combined intervention also decreased the expression levels of the proteins involved in AGEs/RAGE/NF-κB signaling pathway, and improved bone microstructure, finally contributing to increasing bone quality in diabetic mice.Conclusions The combination of loganin and berberine could improve bone metabolism in diabetic mice, which may be related to AGEs/RAGE/NF-κB signaling pathway.
