Abstract
Aim: The present study was carried out to assess the effect of nanoceria (NC) on pancreatic inflammation caused by cerulein. Methods: NC was characterized and in vitro studies were carried out in murine macrophages. The in vivo effects were tested on cerulein-induced pancreatitis. Results:In vitro treatment with NC remarkably protected macrophages from lipopolysaccharide-induced inflammation and oxidative stress as evident from the results of 2',7'-dichlorofluorescin diacetate, JC-1 and MitoSox staining. In vivo treatment with NC showed potent superoxide dismutase and catalase mimetic activity, antipancreatitis activity and improved histology. Furthermore, it reduced the expression of p65-NF-κB and acetylation of histone H3 at lysine K14, K56 and K79 residues. Conclusion: We for the first time, demonstrate that NC may be a promising candidate for the therapy of pancreatitis.
