铁死亡及铁代谢途径与视网膜退行性疾病研究进展OA
Research progress on ferroptosis and iron metabolism pathways in retinal degenerative diseases
铁死亡是一种以铁沉积和脂质过氧化为主要特征的新型细胞死亡方式,目前在眼科方面的研究不断深入.视网膜因其本身功能和结构特点,易受到氧化应激的影响,而铁死亡已被证明在年龄相关性黄斑变性、青光眼、糖尿病性视网膜病变、视网膜色素变性等视网膜退行性疾病进程中发挥了重要作用.铁代谢途径作为铁死亡的主要调控方式之一,可通过调控细胞内铁稳态,介导芬顿反应形成脂质过氧化物,从而调控细胞铁死亡.转铁蛋白(transferrin,TF)、二价金属转运蛋白1(divalent metal transporter 1,DMT1)、铁蛋白(ferritin,FT)、铁转运蛋白1(ferroportin 1,FPN1)等铁代谢途径关键蛋白涉及细胞内铁离子的摄入、利用、储存、输出等多个方面,对细胞内铁稳态具有重要影响.通过调控铁代谢途径关键蛋白减少铁沉积而抑制铁死亡,可能成为延缓和治疗视网膜退行性疾病的新途径.文章对铁死亡概念、视网膜与铁死亡、铁死亡调控途径、铁代谢途径关键蛋白与视网膜退行性疾病的研究进展进行综述.
Ferroptosis,a novel form of cell death primarily characterized by iron deposition and lipid peroxidation,has been increasingly studied in the field of ophthalmology.The retina,due to its specific functions and structure,is susceptible to oxidative stress.Ferroptosis has been proven to play a crucial role in the progression of retinal degenerative diseases such as age-related macular degeneration,glaucoma,diabetic retinopathy,and retinitis pigmentosa.The iron metabolism pathway is one of the main regulatory mechanisms of ferroptosis,regulating intracellular iron homeostasis and mediating the formation of lipid peroxides through the Fenton reaction,thereby controlling cellular ferroptosis.Iron metabolism pathways,as one of the main regulatory mechanisms of ferroptosis,can regulate intracellular iron homeostasis and mediate the formation of lipid peroxides through the Fento reaction,thereby controlling cellur ferroptosis.Key proteins involved in iron metabolism pathways,including transferrin(TF),divalent metal transporter 1(DMT1),ferritin(FT),and ferroportin 1(FPN1),act as important roles in various aspects such as intracellular iron intake,utilization,storage,and export,exerting significant impacts on intracellular iron homeostasis.Regulating key proteins in iron metabolism pathways to reduce iron deposition and inhibiting ferroptosis may emerge aas a novel approach for delaying and treating retinal degenerative diseases.This article provides a comprehensive review of the concept of ferroptosis,the relationship between the retina and ferroptosis,the regulatory mechanisms of ferroptosis,and the research progress on key proteins in iron metabolism pathways and retinal degenerative diseases.
