Rational Design of a Targetable Fluorescent Probe for Visualizing H2S Production under Golgi Stress Response Elicited by Monensin

As a eukaryotic organelle, the Golgi apparatus plays an essential role in various physiological activities such as stress response. The Golgi stress response is an important physiological process of conferring cytoprotection by regulating the synthesis and metabolism of bioactive molecules. Therefore, the development of new suitable in situ analytical techniques for monitoring related small molecular substances in the stress reaction of the Golgi apparatus is very helpful for further study of the regulatory mechanism of the Golgi apparatus. Recent studies have shown that endogenous hydrogen sulfide (H2S) also possesses crucial bioregulatory and protective performances in the stress response. Therefore, the high-fidelity in situ mapping of H2S production under the Golgi stress response plays an important role not only in revealing cytoprotection functions of H2S in the stress response but also in further understanding the regulatory mechanism of the Golgi stress response. In this work, we designed a simple...
