The labile iron pool (LIP) is a pool of chelatable and redox-active iron, not only essential for a wide variety of metabolic process, but also as a catalyst in the Fenton reaction, causing the release of hazardous reactive oxygen species (ROS) with potential for inducing oxidative stress and cell damage. The cellular LIP represents the entirety of every heterogenous sub-pool of iron, not only present in the cytosol, but also in mitochondria, lysosomes and the nucleus, which have all been detected and characterized by various fluorescent methods. Accumulated evidence indicates that alterations in the intracellular LIP can substantially contribute to a variety of injurious processes and initiate pathological development. Herein, we present our understanding of the role of the cellular LIP. To fully review the LIP, firstly, the significance of cellular labile iron in different subcellular compartments is presented. And then, the trafficking processes of cellular labile iron between/in cytosol, mitochondria and lysosomes are discussed in detail. Then, the recent progress in uncovering and assessing the cellular LIP by fluorescent methods have been noted. Overall, this summary may help to comprehensively envision the important physiological and pathological roles of the LIP and shed light on profiling the LIP in a real-time and nondestructive manner with fluorescent methods. Undoubtedly, with the advent and development of iron biology, a better understanding of iron, especially the LIP, may also enhance treatments for iron-related diseases.

胞质溶胶,线粒体和溶酶体中不稳定铁的重要性,贩运和测定

不稳定的铁池(LIP)是可螯合的氧化还原活性铁池,不仅对多种代谢过程必不可少,而且还作为Fenton反应的催化剂,导致释放有害的活性氧(ROS)具有诱导氧化应激和细胞损伤的潜力。细胞LIP代表了铁的每个异质子池的整体,不仅存在于细胞质中,而且还存在于线粒体,溶酶体和细胞核中,这些均已通过各种荧光方法进行了检测和表征。越来越多的证据表明,细胞内LIP的改变可实质上导致多种伤害性过程并引发病理发展。在这里,我们介绍了我们对蜂窝LIP的作用的理解。要全面审查LIP,首先,提出了不同亚细胞区室中细胞不稳定铁的重要性。然后,详细讨论了细胞不稳定铁在胞质溶胶,线粒体和溶酶体之间的运输过程。然后,已经注意到通过荧光方法发现和评估细胞LIP的最新进展。总体而言,本概述可能有助于全面地了解LIP的重要生理和病理作用,并阐明使用荧光方法以实时且无损的方式对LIP进行配置分析。毫无疑问,随着铁生物学的出现和发展,对铁特别是LIP的更好理解也可能会增强对铁相关疾病的治疗。详细讨论了细胞不稳定铁在细胞质,线粒体和溶酶体之间/中的运输过程。然后,已经注意到通过荧光方法发现和评估细胞LIP的最新进展。总体而言,本概述可能有助于全面地了解LIP的重要生理和病理作用,并阐明使用荧光方法以实时且无损的方式对LIP进行配置分析。毫无疑问,随着铁生物学的出现和发展,对铁特别是LIP的更好理解也可能会增强对铁相关疾病的治疗。详细讨论了细胞不稳定铁在细胞质,线粒体和溶酶体之间/中的运输过程。然后,已经注意到通过荧光方法发现和评估细胞LIP的最新进展。总体而言,本概述可能有助于全面地了解LIP的重要生理和病理作用,并阐明使用荧光方法以实时且无损的方式对LIP进行配置分析。毫无疑问,随着铁生物学的出现和发展,对铁特别是LIP的更好理解也可能会增强对铁相关疾病的治疗。该总结可能有助于全面地了解LIP的重要生理和病理作用,并阐明使用荧光方法以实时且无损的方式对LIP进行分析的方法。毫无疑问,随着铁生物学的出现和发展,对铁特别是LIP的更好理解也可能会增强对铁相关疾病的治疗。该总结可能有助于全面地了解LIP的重要生理和病理作用,并阐明使用荧光方法以实时且无损的方式对LIP进行分析的方法。毫无疑问,随着铁生物学的出现和发展,对铁特别是LIP的更好理解也可能会增强对铁相关疾病的治疗。
