Abstract: Objective To observe the expressions of early growth response 1 (Egr-1) and tissue factor (TF) in rat tissues of acute pancreatitis induced by caerulein and to explore their significance.Methods Pancreatitis was induced in rats by high-dose intraabdominal caerulein injection. The changes of Egr-1 mRNA and protein in pancreas were measured by quantitative PCR and Western blotting, and the localization of Egr-1 protein in acinar cells was visualized by immunohistochemistry. TF mRNA levels were also measured by quantitative PCR. High-dose bombesin-stimulated rats served as the negative control.Results Egr-1 mRNA was rapidly increased in the pancreas of rats stimulated by high-dose cearulein, and reached the peak level 30 min after the stimulation, whereas band for peak Egr-1 protein level was visualized by Western blotting till 2 h after stimulation. Immunohistochemistry showed that almost every acinar cell in the pancreas was Egr-1-positive, especially in the nucleus. In line with Egr-1 activation, TF mRNA was detected 1 h after the stimulation and increased steadily within the initial 4 h. Only a small quantity of Egr-1 mRNA expression was observed in bombesin-stimulated rats, in which no Egr-1 protein or TF mRNA were detected.Conclusion Egr-1 mRNA and protein were up-regulated in the early stage of pancreatitis. Egr-1, as a pro-inflammatory transcriptional factor, probably plays an important role in the initiation of acute pancreatitis, and its action might be partially mediated through the up-regulation of TF expression.
