Relevance. The effect of pro-oxidants on the cell can cause different effects depending on the dose and duration of exposure, therefore, adequate experimental models of oxidative stress (OS) in vitro are needed to study these processes.
The aim of the study was to study the dynamics of OS development in endogenous and exogenous in vitro models.
Material and methods. The study was carried out on a line of Caco-2 cells. Hydrogen peroxide (H2O2) and DL-butyonine sulfoximine (BSO) were added to cells at concentrations of 0.1–100 μM s and 1–500 microns, respectively, at the confluence of 3, 24 and 72 hours. At the end of the exposure, the percentage of viable cells was determined (MTT test), the level of reactive oxygen species (MitoTracker Red CM-H2 XRos), the amount of Nrf2 and glutathione peroxidase (ELISA), the concentration of carbonyl derivatives of proteins (photometric method.)
Results. H2O2 at concentrations of 5–50 μM and BSO – 10; 50; 100 μM cause an increase in the level of carbonyl derivatives of proteins, the level of transcription factor Nrf2 and antioxidant enzyme – glutathione peroxidase at exposure time of 24 and 72 hours. The concentration of H2O2 100 μM and BSO 500 μM are toxic to the Caco-2 cell line. The incubation period of 3 hours does not cause the development of OS.
Conclusion. Hydrogen peroxide at concentrations of 5-50 μM, BSO – 10; 50; 100 μM and exposure time of 24 and 72 hours cause the development of compensated oxidative stress (eustress), and H2O2 at concentrations of 100 μM and BSO – 500 μM are toxic to cells of the Caco-2 line.
