Abstract
Heme oxygenase-1 (HO-1) plays a key role in the regulation of the inflammatory response. However, the specific mechanism underlying the anti-inflammatory role of HO-1 in the reproductive system is unclear. The aim of this study was to evaluate the role of the mechanism of HO-1 in the regulation of the inflammatory response stimulated by lipopolysaccharide (LPS) in rat ovary. LPS-stimulated inflammatory models were established. Rats were pretreated with HO-1 activator (hemin) or inhibitor (ZnPP) before LPS stimulation, and we evaluated the expression of HO-1 by real-time PCR and Western blot. The messenger RNA (mRNA) expression and secretion of IL-1β and IL-6 in rat ovary were analyzed using real-time PCR and ELISA. In addition, we also analyzed the p38 and p-p38 protein expression in the ovary. Our results demonstrate that HO-1 is an anti-inflammatory factor in LPS-stimulated ovary, which regulates the inflammatory response through downregulation of p38 signaling pathways in rat ovary.Entities:
