Abstract

The steady-state imbalance of copper ions can lead to an increase in copper ion concentration in the body, causing cell damage and cuproptosis. Copper ions catalyze hydrogen peroxide to produce a large amount of reactive oxygen species, resulting in lipid peroxidation. Lipid peroxidation significantly changes the composition and structure of the membrane, leading to changes in polarity. The polarity changes in different intracellular regions have been recognized as reliable indicators of different diseases, monitoring the polarity of cell membranes and intracellular lipid droplets is of great significance as a diagnostic and research indicator of cuproptosis. Using probes to stain cells and analyzing changes in subcellular organelle microenvironment during cuproptosis using fluorescence lifetime imaging. Establishing a copper induced cell death model through copper death inducers, and real-time monitoring of changes in lipid droplets and cell membrane polarity during cuproptosis process. It was found that under the action of Elesclomol, the lipid droplet content in cells increased significantly, and the fluorescence lifetime of the probe decreased significantly, indicating that the polarity of intracellular lipid droplets increased.



Keywords: cuproptosis, cell microenvironment, fluorescence lifetime imaging, polarity, lipid, cell membrane
