Abstract
At the 2018 PancreasFest meeting, experts participating in basic research met to discuss the plethora of available animal models for studying exocrine pancreatic disease. In particular, the discussion focused on the challenges currently facing the field and potential solutions. That meeting culminated in this review, which describes the advantages and limitations of both common and infrequently used models of exocrine pancreatic disease, namely, pancreatitis and exocrine pancreatic cancer. The objective is to provide a comprehensive description of the available models but also to provide investigators with guidance in the application of these models to investigate both environmental and genetic contributions to exocrine pancreatic disease. The content covers both nongenic and genetically engineered models across multiple species (large and small). Recommendations for choosing the appropriate model as well as how to conduct and present results are provided.

Abstract
Marfan syndrome (MFS) is associated with progressive aortic dilatation and endothelial dysfunction that lead to early acute dissection and rupture of the aorta and sudden death. Alteration in fatty acid (FA) metabolism can stimulate nitric oxide (NO) overproduction which increases the activity of the inducible form of NO synthase (iNOS) that is involved in endothelial dysfunction. We evaluated the participation of FA in the formation of thoracic aneurysms in MFS and its relation to the iNOS. Oleic acid (OA), iNOS, citrulline, nitrates and nitrites, TGF-β1, TNF-α, monounsaturated FA and NO synthase activity were significantly increased (p<0.05) in tissue from the aortas of MFS. Saturated FA, eNOS and HDL were significantly decreased (p<0.05). Arachidonic acid, delta-9 desaturase tended to increase and histological examination showed an increase in cystic necrosis, elastic fibers and collagen in MFS. The increase in OA contributes to the altered pathway of iNOS, which favors endothelial dysfunction and formation of the aortic aneurysms in MFS.

Abstract
Chronic pancreatitis affects many individuals around the world, and the study of the underlying mechanisms leading to better treatment possibilities are important tasks. Therefore, animal models are needed to illustrate the basic study of pancreatitis. Recently, animal models of acute and chronic pancreatitis have been thoroughly reviewed, but few reviews address the important aspect on the translation of animal studies to human studies. It is well known that pancreatitis is associated with epigastric pain, but the understanding regarding to mechanisms and appropriate treatment of this pain is still unclear. Using animal models to study pancreatitis associated visceral pain is difficult, however, these types of models are a unique way to reveal the mechanisms behind pancreatitis associated visceral pain. In this review, the animal models of acute, chronic and un-common pancreatitis are briefly outlined and animal models related to pancreatitis associated visceral pain are also addressed.

Abstract
Animal models for CP in rats can be classified into 2 groups: one is noninvasive or nonsurgical models and the other is invasive or surgical models. Pancreatic injury induced by repetitive injections of supramaximal stimulatory dose of caerulein (Cn) or by intraductal infusion of sodium taurocholate (NaTc) recovered within 14 days, whereas that caused by repetitive injection of arginine or by intraductal infusion of oleic acid was persistent. However, the destroyed acinar tissues were replaced by fatty tissues without fibrosis. Transient stasis of pancreatic fluid flow by 0.01% agarose and minimum injury of the pancreatic duct by 0.1% NaTc solution induced progressive pancreatic injury although one alone is insufficient to cause persistent pancreatic injury. However, the damaged tissue was replaced by fatty tissue without fibrosis. Continuous pancreatic ductal hypertension (PDH) caused diffuse interlobular and intralobular fibrosis closely resembling human CP.

Preferential increase of extracellular matrix expression relative to transforming growth factor beta1 in the pancreas during the early stage of acute hemorrhagic pancreatitis in rats. Pancreas 2007; 35:e23-9.

Abstract
OBJECTIVES To elucidate the role of transforming growth factor (TGF) beta1 and extracellular matrix (ECM) after acute necrotizing pancreatitis, we studied the regulation of TGF-beta1 and ECM after induction of pancreatitis. METHODS We examined the serial changes of levels of plasma TGF-beta1 by enzyme-linked immunoassay and expression of TGF-beta1 and ECM by Northern and Western blot analyses, respectively, in the pancreas after induction of sodium taurocholate-induced acute pancreatitis. RESULTS Plasma total (active and inactive) TGF-beta1 levels at 3 hours after induction of pancreatitis were significantly increased compared with baseline values. The levels of TGF-beta1 messenger RNA (mRNA) were unaltered by day 2. Levels of fibronectin mRNA at 3 hours after induction of pancreatitis were already higher than the baseline values. Latency-associated peptide-TGF-beta1 showed a peak on day 7. Thus, the expression of ECM mRNA increased earlier than that of TGF-beta1 mRNA. CONCLUSIONS These results suggest that the increase in plasma TGF-beta1 concentration probably results from the elevated secretion of TGF-beta1 from several cells and/or the redistribution of TGF-beta1 protein and that the increase in expression of ECM probably is associated with the activation of TGF-beta1. It is conceivable that both increased plasma concentration and focal activation of TGF-beta1 play an important role in ECM production during the early stage of acute pancreatitis.
