Imbalanced GSH/ROS and sequential cell death - PubMed
Imbalanced ROS/GSH may result from a direct increase of ROS, consumption of GSH, intracellular oxidoreductase interference, or thioredoxin activity reduction. Some chemicals including arsenic trioxide (ATO), pyrogallol (PG), and carbobenzoxy-Leu-Leu-leucinal (MG132) could also disrupt the balance of GSH and ROS.
脂质过氧化和铁代谢:铁死亡稳态控制的两个 ... - X-MOL
2022年12月27日 · 减少ROS的主要机制是谷胱甘肽(GSH)的氧化还原能力。 GSH 是一种三肽,包括谷氨酸、半胱氨酸和甘氨酸,可作为抗氧化剂,是谷胱甘肽过氧化物酶 4 (GPX4) 的底物,后者随后会转化为氧化型谷胱甘肽 (GSSG)。 增加 GSH 的表达可以抑制铁死亡。 我们强调 xc-GSH-GPX4 通路作为调节铁死亡的主要通路的作用。 xc- 系统由亚基溶质载体家族成员(SLC7A11 和 SLC3A2)组成,介导胱氨酸和谷氨酸跨质膜交换以合成 GSH。 越来越多的证 …
3篇Cancer Res文章均锁定同一通路!谷胱甘肽代谢通路这么火?
2021年2月22日 · 谷胱甘肽(GSH)是细胞中表达最为丰富的一种抗氧化剂,正常情况下SLC7A11输出大量细胞内的谷氨酸,以换取细胞外的胱氨酸,SLC7A11导入的胱氨酸则转化为半胱氨酸,支持谷胱甘肽生物合成和ROS解毒(下图-a)。 在葡萄糖剥夺条件下,SLC7A11导入的胱氨酸会消耗NAPDH并诱导ROS,与此同时,由于缺乏足够的糖酵解供能TCA循环和线粒体呼吸难以维持(下图-b)。 From Koppula, P. et al, 2018. 本文我们将分享3篇GSH代谢通路机制的 …
