[Role of Mitochondria in Ferroptosis and Its Relationship to Tumors]. [PDF]

open access: yesZhongguo Fei Ai Za Zhi
铁死亡是近年来新发现的一种区别于凋亡的细胞死亡形式,以细胞内铁的累积和脂质过氧化水平增加为主要特征。肿瘤细胞对铁死亡的抵抗会促进肿瘤的发生发展;多种化合物能通过触发铁死亡来影响肿瘤进展。铁死亡存在复杂的调控机制,而线粒体作为铁的储存中心与代谢中心,对铁死亡起重要的调控作用。本文就铁死亡及其三个阶段、线粒体对铁死亡的调控机制以及铁死亡在肿瘤发生发展与治疗中的作用做一综述。

[Inhibition of Lung Squamous Cancer Target HMGCS1 Promotes Cellular Ferroptosis]. [PDF]

open access: yesZhongguo Fei Ai Za Zhi
背景与目的 靶向治疗在肺鳞癌中的效果不理想,而免疫治疗较低的应答率阻碍了其在肺鳞癌中的应用,因此,探索肺鳞癌治疗的新策略十分迫切。铁死亡在抑制肿瘤方面发挥了重要作用,本研究旨在探究靶向3-羟基-3-甲基戊二酰辅酶A合酶1(3-hydroxy-3-methylglutaryl-CoA synthase 1, HMGCS1)对肺鳞癌细胞铁死亡的调控和作用机制,为肺鳞癌治疗提供新的研究思路和方向。 方法 通过肿瘤基因组图谱(The Cancer Genome Atlas, TCGA)和临床蛋白质组肿瘤分析联盟(

Research progress in ferroptosis regulation in the treatment of liver diseases [PDF]

open access: yes, 2023
Ferroptosis is a form of cell death that results from accumulation of lipid reactive oxygen species, marked by iron-dependent oxidative damage of phospholipids. Accumulation of iron and lipid hydroperoxides are hallmarks of ferroptosis.

运动训练促进脑卒中后神经可塑性的机制研究 [PDF]

open access: yes, 2021
运动训练是脑卒中后康复治疗的主要手段。运动训练可以促进脑卒中后神经功能的恢复,其作用目前普遍认为与神经可塑性有关,但具体机制未明。运动训练的神经可塑性机制是当前脑卒中康复研究领域的热点问题。运动训练可以调节脑卒中后脑内血流动力学变化、血管新生、神经炎症反应、营养因子分泌、神经细胞死亡及新生等。本文基于国内外研究,探讨脑卒中后最适的运动干预方案,并结合我们团队在运动训练促进脑卒中后神经功能恢复方向所做的系列研究工作 ...

铁死亡:心肌缺血再灌注损伤分子机制和药物治疗研究新靶点

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2022
心肌缺血/再灌注损伤(I/R)是再灌注治疗的重要并发症,也是心血管疾病和急危重症患者死亡的主要原因之一,其发病机制复杂,目前临床上尚缺乏有效的防治措施。铁死亡(ferroptosis)是近年来发现的一种全新的调节性细胞死亡方式,是各类疾病发病机理及治疗靶点的热点研究领域。已有研究指出铁死亡与心肌I/R的病理生理过程密切相关。本文综述了近年来铁死亡在心肌I/R中的相关研究进展,以期为心肌I/R的预防和治疗提供新参考。
