endocrine/exocrine glands
|
• glands of the nasal mucosa and maxillary sinus contain proliferating immature ductal cells and are incompletely differentiated
|
|
• hyperplastic lesions of the parotid salivary glands
|
|
• hyperplastic lesions of the sublingual salivary glands
• occasionally observe serous metaplasia in the sublingual gland
|
|
• hyperplastic lesions of the submandibular salivary glands
|
|
• major and minor salivary glands show severe ductular hyperplasia and incomplete differentiation
• proliferating ductules appear to consist of immature cell types
|
|
• focal and often multiple poorly differentiated salivary adenocarcinomas appear in the majority of transgenics between 2 and 6 months of age
|
 |
• hyperplastic nodular lesions and multifocal neoplastic lesions at multiple sites in the fat pad of mammary glands
• mammary gland secretory lobules and alveoli are absent in parous females
|
|
|
• inguinal mammary gland development is incomplete, with mutants showing a truncated version of the normal glandular penetration of the mammary fat pat and absence of end buds
• mammary gland alveolar and ductal structures are sparse
• in parous females, lobular-alveolar development is incomplete; secretory lobules and alveoli are largely missing
|
|
• focal and often multiple poorly differentiated mammary adenocarcinomas appear in the majority of transgenics between 2 and 7 months of age
|
|
• hyperplasia of immature ductal cells is seen frequently in the Harderian gland
|
|
|
• parous females fail to lactate
|
neoplasm
|
• focal and often multiple poorly differentiated salivary adenocarcinomas appear in the majority of transgenics between 2 and 6 months of age
|
|
• focal and often multiple poorly differentiated mammary adenocarcinomas appear in the majority of transgenics between 2 and 7 months of age
|
|
• lung metastases in 4 of 7 mutants with mammary tumors
|
reproductive system
 |
• epididymis occasionally contains reduced sperm count
|
|
|
• the pseudostratified epithelium of the epididymis is disorganized
|
|
|
• males exhibit severe epididymal hyperplasia
|
digestive/alimentary system
|
• hyperplastic lesions of the parotid salivary glands
|
|
• hyperplastic lesions of the sublingual salivary glands
• occasionally observe serous metaplasia in the sublingual gland
|
|

|
vision/eye
|
• hyperplasia of immature ductal cells is seen frequently in the extraorbital lacrimal gland
|
integument
|
|
• hyperplastic nodular lesions and multifocal neoplastic lesions at multiple sites in the fat pad of mammary glands
