摘要

自噬和有丝分裂是重要的细胞质量控制系统，调节这两个系统可为危重疾病提供治疗潜力。然而，有限的药物筛选方案阻碍了研究的进展。我们介绍了一种利用光开关荧光报告物 mito-Kaede 来量化有丝分裂通量的新型检测方法。Mito-Kaede 具有优异的紫外线诱导光电转换能力和转换后的亮度，因此非常适合用于长时间的线粒体动态跟踪。经 Parkin 基因敲除细胞证实，它对有丝分裂反应的特异性增加了其价值。如果与定制的液体交换系统配合使用，就能有效地更换培养基，从而实现对有丝分裂的精确观察。这种有丝分裂检测方法与我们的方法论见解相结合，可以破译有丝分裂在病理学中的作用，并为药物筛选工作提供支持。

Mito-kaede photoactivation and chase experiment for mitophagy: optimizing flux measurement via fluid exchange system.

Modulating autophagy and mitophagy, vital cellular quality control systems, offer therapeutic potential for critical illnesses. However, limited drug screening options hinder progress. We present a novel assay using the photoswitchable fluorescent reporter, mito-Kaede, to quantify mitophagy flux. Mito-Kaede's superior UV-induced photoconversion and brightness post-conversion make it ideal for prolonged mitochondrial dynamics tracking. Its specificity in responding to mitophagy, confirmed by parkin-knockout cells, adds value. When coupled with a custom fluid exchange system, enabling efficient medium changes, precise mitophagy observations become feasible. This mitophagy assay, alongside our methodological insights, can decipher mitophagy's role in pathology and supports drug screening efforts.
