Platycoside G1 Inhibits Hepatocyte Senescence by Regulating Autophagy [PDF]
To investigate the effects of platycoside G1 (PG1) on senescent cells, it was determined that PG1 exerts a specific inhibitory effect on the senescent phenotype of hepatocytes by employing β-galactosidase staining and the cell counting kit-8 (CCK-8 ...

神经退行性变性疾病是一类由大脑和脊髓神经元退化并死亡所引发的疾病,至今缺乏有效的治疗方法。过氧亚硝酸盐是一种神经毒性物质,研究表明体内活性氧的过度积累与神经退行性变性疾病紧密相关。有效清除过氧亚硝酸盐的策略可能成为治疗神经退行性变性疾病的一种潜在途径。一些水溶性金属卟啉因其高效的过氧亚硝酸盐清除能力备受关注,常见金属卟啉如铁卟啉和锰卟啉通过抑制淀粉样斑块聚集、减轻氧化应激和神经炎症损伤、改善线粒体功能以及减少神经细胞凋亡等发挥神经保护作用。部分金属卟啉的血脑屏障穿透性不佳,除采用传统的合成工艺外 ...

随着全球人口老龄化进程的加快,肌少症作为一种以骨骼肌质量、力量与躯体功能持续性下降为特征的老年综合征,已成为严重威胁老年人健康和生活质量的重要公共卫生问题。其发生发展过程涉及多层次、跨系统的细胞与分子机制。近年来研究发现,程序性细胞死亡(PCD)在骨骼肌稳态维持、代谢调节与组织修复中发挥核心作用。凋亡、自噬、焦亡与铁死亡等典型PCD形式通过活性氧(ROS)积聚、线粒体功能障碍与铁稳态破坏等关键节点相互串扰,驱动肌纤维丢失、肌肉功能减退及慢性炎症反应,是肌少症发生发展的重要病理基础 ...
