neoplasm
• focal morphological lesions develop in acinar and centroacinar cells at 1-3 months
• acinar to ductal metaplasias develop
• some mice develop ductal adenocarcinomas by 12 months
• properties are similar to those in human patients
• sometimes areas of non malignant hyperplasia develop
• latency is increased if gene expression is delayed by maintaining exposure to doxycycline until 10 days of age
• if doxycycline exposure continues to 2 months of age, no pancreatic abnormalities develop

endocrine/exocrine glands
• focal morphological lesions develop in acinar and centroacinar cells at 1-3 months
• acinar to ductal metaplasias develop
• some mice develop ductal adenocarcinomas by 12 months
• properties are similar to those in human patients
