Cytoprotective Action of Sodium Fumarate in an in vitro Model of Hypoxia Using Sodium Dithionite
Year: 2025
Type: article
Abstract: by reducing oxygen in the medium using sodium dithionite. Materials and Methods: and the pH level in the cytosol, the rate of glucose absorption by cells, and cell death) were assessed by means of confocal and wide-field fluorescence microscopy. The concentration of dissolved oxygen was established using the polarographic method with a Clark electrode. Results: with a rapid decrease in the oxygen concentration in the cell incubation medium, which resulted in a change in mitochondrial function and the apoptosis progression. At that, sodium fumarate reduces the level of cell death, which is associated not with the restoration of the ATP-producing ability of mitochondria, but rather with an increase in the contribution of alternative sources of high-energy compounds. Conclusion: At the cellular level, using an optimized hypoxia model, the study revealed the mechanism of the protective role of sodium fumarate, which explained the antihypoxant effectiveness in assisted ischemia of organs and tissues.
