南昌大学生命科学学院人类衰老研究所向阳团队在Journal of Cachexia, Sarcopenia and Muscle报道肌肉萎缩干预新分子——野菊花内酯（图）
人类衰老 Journal of Cachexia Sarcopenia and Muscle 肌肉萎缩 野菊花内酯 向阳 骨骼肌
2024/8/12
向阳课题组前期发现野菊花提取物可以防治紫外损伤导致的皮肤光老化，进一步发现野菊花提取物可以延长秀丽隐杆线虫寿命，并发现野菊花内酯为其重要有效成份。野菊花内酯（Handelin）可以维持老年线虫肌肉结构完整性并改善其运动功能（Biogerontology 2022）。在本研究中，团队进一步在脂多糖诱导的小鼠肌肉萎缩模型及自然衰老小鼠肌少症模型探索野菊花内酯对骨骼肌的保护作用，发现其可以增加肌肉质量、...
In recent years, scientists who study gene expression in cells have used a method that essentially pins a tail on RNA and tracks their whereabouts. However, certain types of RNA evade the process. Now...
