ABSTRACT
Objective To evaluate the role of early growth response gene1 (Egr-1) in liver injury in taurocholate-induced acute pancreatitis rat model. Methods Twenty-four male rats were divided into 4 groups. Egr-1 immunohistochemistry staining and pancreatic pathologic scoring were assessed, and the serum levels of AST, LDH, TNF-? and IL-1 ? were measured. Egr-1 mRNA levels of primary hepatocyte culture stimulated with TNF-? and pretreated primary hepatocytes with PD98059 followed by TNF-? stimulation were also observed. Results Egr-1 expression of liver correlated with degree of liver injury in acute pancreatitis in rat, and high Egr-1 mRNA expression of primary hepatocyte was observed when hepatocyte injury occurred. After pretreated with PD98059, TNF-?-stimulated hepatocytes showed a lower level of Egr-1 mRNA compared with hepatocytes without pretreatment. Conclusions Egr-1 may play an important role in liver injury in acute pancreatitis, and this effect depended partly upon extracellular signal-regulated kinase 1/2 (ERK1/2) pathway.
