Up-regulation of Tight-Junction Proteins by p38 Mitogen-Activated Protein Kinase/p53 Inhibition Leads to a Reduction of Injury to the Intestinal Mucosal Barrier in Severe Acute Pancreatitis

These results suggest that SAP activates the p38MAPK/p53 signaling pathway and induces injury to the intestinal mucosal barrier, which can be alleviated by inhibiting the p38MAPK/p53 pathway.
