Mitochondrial dynamics in health and disease: mechanisms and potential targets

Wen Chen,
Huakan Zhao,
Yongsheng Li

Abstract: Mitochondria are organelles that are able to adjust and respond to different stressors and metabolic needs within a cell, showcasing their plasticity and dynamic nature. These abilities allow them to effectively coordinate various cellular functions. Mitochondrial dynamics refers to the changing process of fission, fusion, mitophagy and transport, which is crucial for optimal function in signal transduction and metabolism. An imbalance in mitochondrial dynamics can disrupt mitochondrial function, leading to ab… Show more

“…The disruption of mitochondrial homeostasis is associated with several pathologies, such as neurodegeneration, cancer, aging, and cardiovascular diseases (Chen et al, 2023; Norat et al, 2020; Quirós et al, 2016; Suomalainen and Battersby, 2018). The UPRmt is an evolutionarily conserved homeostatic pathway engaged upon a wide range of mitochondrial insults, including mitochondrial protein misfolding (Zhao et al, 2002), reduced mitochondrial protein import efficiency (Nargund et al, 2012), dissipation of mitochondrial membrane potential (Donehower et al, 2019), and dysregulated levels of reactive oxygen species (ROS) (Wang et al, 2022b).…”

“…Mitochondrien sind Zellorganellen, die hauptsächlich die Aufgabe der ATP-Produktion übernehmen, jedoch auch bei vielen Stoffwechselvorgängen eine wichtige Rolle spielen 1 , 2 . Sie bestehen aus der inneren und der äußeren Mitochondrienmembran, dabei grenzt die äußere Membran das Mitochondrium vom Zellplasma ab.…”

“…Es kommt zu oxidativen Schäden an Proteinen, der mitochondrialen DNA und den Membranlipiden, wodurch die Funktion der an der Elektronenübertragung beteiligten Enzyme eingeschränkt wird. Dies beeinträchtigt auch die Energiegewinnung im Rahmen der Atmungskette – eine mitochondriale Dysfunktion ist die Folge 2 .…”
