Front Pharmacol:腺苷受体激动剂可有效预防和治疗骨质疏松症

2017-10-03 MedSci MedSci原创

糖皮质激素诱导的骨质疏松症(GIO)是导致骨质流失的次要原因。用于治疗GIO的二膦酸酯可能引起颌骨坏死,因此需要额外的治疗。腺苷受体激动剂是骨重塑的正调节因子,因此本研究探究了腺苷受体激动剂治疗GIO的效果。在GIO预防性研究中,研究人员通过甲泼尼龙(MP)在Sprague-Dawley大鼠中诱导GIO 60天。然后随机分配动物接受多脱氧核糖核酸(PDRN),一种腺苷A2受体激动剂或PDRN和DM

糖皮质激素诱导的骨质疏松症(GIO)是导致骨质流失的次要原因。用于治疗GIO的二膦酸酯可能引起颌骨坏死,因此需要额外的治疗。腺苷受体激动剂是骨重塑的正调节因子,因此本研究探究了腺苷受体激动剂治疗GIO的效果。

在GIO预防性研究中,研究人员通过甲泼尼龙(MP)在Sprague-Dawley大鼠中诱导GIO 60天。然后随机分配动物接受多脱氧核糖核酸(PDRN),一种腺苷A2受体激动剂或PDRN和DMPX(3,7-二甲基-1-炔丙基黄嘌呤,A2拮抗剂)或药物赋形剂(0.9%NaCl)。另外一组动物用于治疗研究,MP诱导60天后将大鼠随机分组分别接受PDRN或PDRN和DMPX(腺苷A2受体拮抗剂)或唑来膦酸钠(作为对照金标准治疗)或药物赋形剂。对照动物给予药物赋形剂60天或120天。

经组织学、成像和断裂强度分析处理后,分析小鼠股骨。MP治疗引起严重的骨质流失,同时使用PDRN可防止骨质疏松症的进展。在治疗120天的大鼠中,PDRN恢复股骨骨骼结构和骨强度,增加b-ALP、骨钙素、骨保护素和刺激Wnt经典和非经典信号通路。唑来膦酸钠减少骨吸收并改善组织学特征,对骨形成没有明显影响。

总之,该研究结果表明,腺苷受体激动剂可能有助于预防和治疗GIO。
