Inhibition of NOX4-Mediated ROS Production Contributes to Selenomethionine's Anti-Inflammatory Effect in LPS-Stimulated Bovine Endometrial Epithelial Cells.

ABSTRACT: Bovine endometritis can be caused by Escherichia coli (E. coli), from which the lipopolysaccharide (LPS) triggers TLR4/NF-κB-mediated inflammation and reactive oxygen species (ROS) overproduction, resulting in impaired reproductive performance. While NADPH oxidase (NOX) is a critical source of ROS generation, its role in bovine endometrial epithelial cells (BEEC) and modulation by selenium remains unexplored. In this study, primary BEEC was challenged by LPS to assess NOX2/4 expression kinetics. Inhibitors of NOX and NF-κB were applied to observe the role of NOX-derived ROS in BEEC inflammation and in selenomethionine (SeMet)-modulated anti-inflammation. ROS levels were measured by flow cytometry. The changes in inflammatory cytokines, and the proteins related to NOX4 and NF-
