Protective effects of methylsulfonylmethane (MSM) on barrier function injury of porcine intestinal epithelial cells (IPEC-J2) induced by lipopolysaccharide (LPS)
Abstract Methylsulfonylmethane (MSM) is a natural organic sulfur component that has anti-inflammatory and antioxidant properties. In this study, injury of porcine intestinal epithelial cell (IPEC-J2) models were used to investigate the effect of MSM on lipopolysaccharide (LPS)-induced porcine intestinal epithelium barrier damage. The results of the cell cycle showed that the cells in the G2/M phase decreased significantly with the supplementation of 300 mmol/L MSM (P < 0.05). The ELISA assay revealed that MSM could significantly inhibit the expression of tumor necrosis factor-alpha, interleukin-1, and interleukin-6 (P < 0.01). Meanwhile, MSM could significantly increase the value of cell monolayer transepithelial electrical resistance while reducing the FITC-dextran flux permeability and lactate dehydrogenase activity in IPEC-J2 cells (P < 0.01). Additionally, 300 mmol/L MSM significantly increased both mRNA and protein expression of occludin, claudin-1, and ZO-1 (P < 0.05). Furthermore, MSM prevented the downregulation of epidermal growth factor receptor (EGFR) by LPS, indicating that MSM might enhance tight junction function through mechanisms of activation of EGFR-mediated protein synthesis in IPEC-J2 cells. Therefore, our findings suggested that MSM has protective effects on inflammation and epithelial barrier injury in LPS-induced IPEC-J2 cells, indicating that MSM might be used as a potential therapeutic agent in the pig industry.
