摘要
目的探讨尿石素A(urolithin A,UA)对糖尿病小鼠心脏的保护作用及其机制。方法健康♂C57BL/6小鼠连续6 d腹腔注射链脲佐菌素诱导糖尿病模型,UA连续灌胃11周,并定期检测体质量和随机血糖。在第17周行超声检测心功能,Western blot法测定心肌组织内间质胶原蛋白的变化。高糖33.3 mmol·L-1刺激心肌成纤维细胞,并给予UA进行处理。荧光探针和Western blot法检测线粒体自噬及极性受损线粒体含量的变化情况。结果 UA对小鼠的体质量、血糖、糖耐量、心功能均无明显影响。但能明显改善糖尿病小鼠心脏舒张功能障碍、减少心肌组织内FN和CollagenⅠ蛋白的表达。UA可激活心肌成纤维细胞内被高糖抑制的线粒体自噬。同时UA减少了极性受损线粒体的含量。UA的保护作用被线粒体自噬抑制剂Mdivi-1逆转。结论 UA通过诱导细胞内的线粒体自噬,发挥了改善糖尿病小鼠心脏损伤的作用。
