As the primary consumers of oxygen within all aerobic organisms, mitochondria are a major source of cellular reactive oxygen species (ROS) derived from the in vivo chemistry of oxygen metabolism. Mitochondrial ROS have been traditionally implicated in aging and in a variety of pathologies, including cancer, neurodegeneration, and diabetes, but recent studies also link controlled mitochondrial ROS fluxes to cell regulation and signaling events. Progress in the development of mitochondrial-targeted fluorescent small-molecule indicators that detect specific ROS with high selectivity offers a promising approach for interrogating mitochondrial ROS production, trafficking, and downstream biological effects.
作为所有需氧生物中氧气的主要消费者,线粒体是细胞内活性氧(ROS)的主要来源,这些 ROS 来源于氧代谢的体内化学反应。线粒体 ROS 传统上与衰老和多种病理学有关,包括癌症、神经退行性疾病和糖尿病,但最近的研究也将受控的线粒体 ROS 通量与细胞调节和信号事件联系起来。开发靶向线粒体的荧光小分子指示剂的进展,这些指示剂可以高选择性地检测特定的 ROS,为研究线粒体 ROS 的产生、运输和下游生物学效应提供了一种很有前途的方法。
