ROLE OF PREGNAN-X-RECEPTOR IN CELL RESISTANCE TO NITROSATIVE AND OXIDATIVE STRESS

Abstract

The article discusses the new role of pregnane X receptor (PXR) under conditions of oxidative and nitrosative stress. The results showed that the effect of hydrogen peroxide and S-nitrosoglu-tathione in high concentrations on Caco-2 cells leads to a decrease in cell viability, which is accompanied by an increase in the amount of PXR. These changes are offset by the addition of ketoconazole (inhibitor of PXR) to the medium.
