Abstract
As one of the most vital organelles within biological cells, mitochondria hold an irreplaceable status and play crucial roles in various diseases. Research and therapies targeting mitochondria have achieved significant progress in numerous conditions. Throughout an organism's lifespan, mitochondrial dynamics persist continuously, and due to their inherent characteristics and various external factors, mitochondria are highly susceptible to damage. This susceptibility is particularly evident during aging, where the decline in biological function is closely intertwined with mitochondrial dysfunction. Despite being an ancient and enigmatic organelle, much remains unknown about mitochondria. Here, we will explore the past and present knowledge of mitochondria, providing a comprehensive review of their intrinsic properties and interactions with nuclear DNA, as well as the challenges and impacts they face during the aging process.
线粒体是生物细胞内最重要的细胞器之一，具有不可替代的地位，在各种疾病中发挥着至关重要的作用。针对线粒体的研究和疗法在多种疾病中取得了重大进展。在生物体的整个生命周期中，线粒体的动态变化持续存在，由于其固有的特性和各种外部因素，线粒体极易受到损伤。这种易损性在衰老过程中尤为明显，生物功能的衰退与线粒体功能障碍密切相关。尽管线粒体是一个古老而神秘的细胞器，但人们对它仍有许多未知。在这里，我们将探讨线粒体过去和现在的知识，全面回顾线粒体的内在特性、与核 DNA 的相互作用，以及线粒体在衰老过程中面临的挑战和影响。
期刊介绍：
The journal Biogerontology offers a platform for research which aims primarily at achieving healthy old age accompanied by improved longevity. The focus is on efforts to understand, prevent, cure or minimize age-related impairments.
Biogerontology provides a peer-reviewed forum for publishing original research data, new ideas and discussions on modulating the aging process by physical, chemical and biological means, including transgenic and knockout organisms; cell culture systems to develop new approaches and health care products for maintaining or recovering the lost biochemical functions; immunology, autoimmunity and infection in aging; vertebrates, invertebrates, micro-organisms and plants for experimental studies on genetic determinants of aging and longevity; biodemography and theoretical models linking aging and survival kinetics.
