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 ...

浙江大学学报. 医学版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 ...

Zhongshan Daxue xuebao. Yixue kexue ban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 ...

Zhongshan Daxue xuebao. Yixue kexue ban脊髓损伤（SCI）作为一种常见的神经系统疾病，主要由机械性创伤引起，通常会导致患者出现大范围的感觉、运动和自主神经损伤，严重影响患者生存质量。近年来研究发现，凋亡、坏死性凋亡、自噬、焦亡、铁死亡以及铜死亡等调节性细胞死亡（RCD）的发生机制与SCI的发生发展密切相关，且各RCD之间还存在一定的串扰关系。因此，本文将对SCI发病过程中与RCD相关的机制和基于细胞死亡抑制剂、外泌体和组织工程疗法治疗SCI的最新研究进展进行综述，以期为未来SCI相关基础研究及临床治疗提供参考。
