tumorigenesis
N
• male mice do not develop tumors in the mammary gland or seminal vesicles (J:193377)
• thoracic and inguino-abdominal mammary gland tumors with latency dependent on nulliparous or multiparous condition (J:193377)
• however, treatment with PI3K inhibitor inhibits tumor growth (J:193377)

integument
• precocious lobulo-alveolar development and hyper-branched ductal structures (2-fold increase in ductal branch point) at 12 weeks (J:193377)
• feathery, hyper-branched ductal tree by 50 weeks (J:193377)

endocrine/exocrine glands
