Abstract

Hypoxia triggers several mechanisms to adapt cells to a low oxygen environment. Mitochondria are major consumers of oxygen and a potential source of reactive oxygen species (ROS). In response to hypoxia they exchange or modify distinct subunits of the respiratory chain and adjust their metabolism, especially lowering the citric acid cycle. Intermediates of the citric acid cycle participate in regulating hypoxia inducible factors (HIF), the key mediators of adaptation to hypoxia. Here we summarize how hypoxia conditions mitochondria with consequences for ROS-production and the HIF-pathway.

摘要

缺氧触发多种机制以使细胞适应低氧环境。线粒体是氧气的主要消耗者和活性氧(ROS)的潜在来源。在缺氧反应中,它们会交换或修饰呼吸链的不同亚基并调整其代谢,特别是降低柠檬酸循环。柠檬酸循环的中间产物参与调节缺氧诱导因子(HIF),这是适应缺氧的关键介质。在这里,我们总结了缺氧如何影响线粒体,进而对ROS产生和HIF途径产生影响。
