A critical obstacle to understanding the role of chronic pancreatitis is the lack of animal models. To develop one such model, mice were fed long-term with a choline deficient ethionine-supplemented (CDE) diet. Histological evaluation revealed that chronic pancreatitis, characterized by acinar atrophy, fibrosis and well-developed tubular complexes (TCs), was observed after 24 weeks of CDE diet treatment. Furthermore, expression of epidermal growth factor receptor (EGFR) and its ligands; serine protease inhibitor Kazal type 3 (Spink3) and transforming growth factor α (TGF α) and activation of K-Ras (GTP-Ras formation), which are frequently observed in human PDA, were indeed observed in parallel with TCs formation. Neoplastic lesions were not found after 54 weeks of treatment, suggesting that a continuation of CDE diet or another insult is required for the development of PDA., http://www.jstage.jst.go.jp/article/expanim/59/4/59_421/_article/-char/ja/}, pages = {421--429}, title = {Chronic Pancreatitis in Mice by Treatment with Choline-Deficient Ethionine-Supplemented Diet}, volume = {59}, year = {2010}, yomi = {タカモリ, ヒロシ and イダ, サトシ and アラキ, キミ} }
