Mitochondria are double-membrane organelles that provide the majority of a cell's energy. Furthermore, mitochondria are involved in various cellular biological activities, including calcium signalling, reactive oxygen species production, apoptosis, cell development, and the cell cycle. Mitochondrial dysfunction is seen in various neurological conditions involving acute and chronic neural injury, including neurodegenerative diseases, hypoxia-induced brain injury, and ischemia. This review made a significant contribution to the explanation of the idea that mitochondria would both be critical targets of ischemia-induced processes, including intracellular calcium elevation and reactive oxygen species and essential sites for determining cell viability loss. As a result, it's not unexpected that attempts to prevent I/R damage have focused on mitochondria. Drugs such as vatiquinone, vitexin, dexprmipexole, baicalin, nobiletin, via promoting mitochondrial activities, can be used in future studies for protecting the brain from ischemia injury. This review summarizes mitochondrial pathways, i.e., Bad, Drp-1, JNK/caspase-3, MAPK-ERK, p53, Wnt/β-Catenin, that contribute to disease progression. We have précised the potential regulatory role of miRNA-mitochondrial dynamics in cerebral ischemic-reperfusion injury and associated molecular mechanisms; also provide insight into the potential therapies for cerebral injury-induced injuries.
线粒体是双层膜细胞器,提供细胞的大部分能量。此外,线粒体还参与各种细胞生物学活动,包括钙信号转导、活性氧物种的产生、细胞凋亡、细胞发育和细胞周期。在涉及急性和慢性神经损伤的各种神经疾病中,如神经退行性疾病、缺氧诱导的脑损伤和缺血,都观察到线粒体功能障碍。这篇综述对线粒体既是缺血诱导过程的关键靶点的观点做出了重要贡献,包括细胞内钙升高和活性氧物质以及决定细胞活力丧失的重要部位。因此,试图防止 I/R 损伤的努力集中在线粒体上也就不足为奇了。未来的研究可以使用促进线粒体活性的药物,如瓦替喹酮、牡荆素、地昔帕明、黄芩素、诺必灵、维甲素,以保护大脑免受缺血损伤。这篇综述总结了导致疾病进展的线粒体途径,即 Bad、Drp-1、JNK/caspase-3、MAPK-ERK、p53、Wnt/β-Catenin。我们详细说明了 miRNA-线粒体动力学在脑缺血再灌注损伤中的潜在调节作用及其相关分子机制;还为脑损伤诱导损伤的潜在治疗方法提供了新的见解。
