摘要

铁死亡是最近发现的一种依赖铁的程序性细胞死亡形式,其特征是脂质活性氧(ROS)的积累。它表现出与其他形式的细胞死亡截然不同的形态学特征,如线粒体体积减少,双层膜密度增加,线粒体嵴减少,但没有任何核变化。铁下垂主要受铁积累和脂质过氧化两个核心生化过程的调控。脂质过氧化物通过扰乱双脂细胞膜的完整性、结构和组成来发挥其毒性作用。然而,作为高活性化合物,它们进一步繁殖ROS的产生,导致DNA和蛋白质的交联。铁死亡的关键调控因子包括上述途径中涉及的各种基因,抗氧化系统的抑制和氧化系统的上调。近年来的研究表明,嗜铁途径参与了包括癌症在内的许多疾病的病理生理过程。了解这一途径的生化机制和关键物质的上调/抑制,可能对开发针对各种癌症的靶向治疗具有重要意义,因此已成为生物医学研究的热点。本文综述了铁下垂的核心生化过程,并对其在各种疾病中的作用和可能的治疗靶点进行了简要综述。

Ferroptosis-molecular mechanisms and newer insights into some diseases
Ferroptosis is a recently discovered iron dependent form of programmed cell death, characterized by accumulation of lipid reactive oxygen species (ROS). It shows a strikingly different set of morphological characteristics from other forms of cell death, like reduced mitochondrial volume, increased bi-layer membrane density, and reduction of mitochondrial cristae with absence of any nuclear changes. Ferroptosis is mainly regulated by two core biochemical processes, namely iron accumulation and lipid peroxidation. Lipid peroxides exert their toxic effects by disturbing the integrity, structure and composition of bi-lipid cell membranes. However, being highly reactive compounds, they further propagate the generation of ROS, leading to cross-linking of DNA and proteins. Key regulators of ferroptosis include various genes involved in the above pathways, inhibition of the antioxidant system and upregulation of the oxidant system. Recent studies have shown the ferroptotic pathway to be involved in the patho-physiology of many diseases, including cancer. Understanding the biochemical mechanisms and key substances upregulating/inhibiting this pathway, may have an implication towards development of targeted therapies for various cancers, and, hence, has become a hotspot for biomedical research. This review article summarizes the core biochemical processes involved in ferroptosis, with a brief summary of its role in various diseases and possible therapeutic targets.
