Abstract

Mitochondria, pivotal to cellular metabolism, serve as the primary sources of biological energy and are key regulators of intracellular calcium ion storage, crucial for maintaining cellular calcium homeostasis. Dysfunction in these organelles impairs ATP synthesis, diminishing cellular functionality. Emerging evidence implicates mitochondrial dysfunction in the etiology and progression of diverse diseases. Environmental factors that induce mitochondrial dysregulation raise significant public health concerns, necessitating a nuanced comprehension and classification of mitochondrial-related hazards. This review systematically adopts a toxicological perspective to illuminate the biological functions of mitochondria, offering a comprehensive exploration of how toxicants instigate mitochondrial dysfunction. It delves into the disruption of energy metabolism, the initiation of mitochondrial fragility and autophagy, and the induction of mutations in mitochondrial DNA by mutagens. The overarching objective is to enhance our understanding of the repercussions of mitochondrial damage on human health.

环境毒理学中的线粒体功能障碍:环境毒理学中的线粒体功能障碍:机理、影响和健康意义》。
线粒体是细胞新陈代谢的关键,是生物能量的主要来源,也是细胞内钙离子储存的关键调节器,对维持细胞钙平衡至关重要。这些细胞器的功能障碍会影响 ATP 合成,从而削弱细胞功能。新的证据表明,线粒体功能障碍与多种疾病的病因和进展有关。诱发线粒体失调的环境因素引发了重大的公共卫生问题,因此有必要对线粒体相关危害进行细致的理解和分类。本综述系统地从毒理学的角度阐明了线粒体的生物功能,全面探讨了毒物如何导致线粒体功能障碍。它深入探讨了能量代谢的破坏、线粒体脆性和自噬的引发,以及突变物对线粒体 DNA 变异的诱导。总体目标是加深我们对线粒体损伤对人类健康影响的理解。

期刊介绍: Chemical Research in Toxicology publishes Articles, Rapid Reports, Chemical Profiles, Reviews, Perspectives, Letters to the Editor, and ToxWatch on a wide range of topics in Toxicology that inform a chemical and molecular understanding and capacity to predict biological outcomes on the basis of structures and processes. The overarching goal of activities reported in the Journal are to provide knowledge and innovative approaches needed to promote intelligent solutions for human safety and ecosystem preservation. The journal emphasizes insight concerning mechanisms of toxicity over phenomenological observations. It upholds rigorous chemical, physical and mathematical standards for characterization and application of modern techniques.
