endocrine/exocrine glands
• ductolobular regression was achieved with somewhat slower kinetics in mutant mice during glandular involution after pregnancy
• a delay in the kinetics of ductolobular development was apparent at 18.5 dpc, when mutant mice showed significantly less glandular remodeling
• at 7.5 dpp, this defect had resolved, such that no deficiencies were apparent in nursing and pups showed no signs of malnutrition
• 8% of elderly animals of >1 year of age exhibited developed poorly differentiated tumors
• DMBA treated animals developed poorly differentiated tumors, characterized by low tubule formation, high mitotic indices, and high degrees of nuclear pleomorphism and relative increase in lymphocyte infiltration compared with mice carrying one wild-type allele of Bin1
• ovarian granulosa cell tumors are noted
• increased incidence of DMBA-induced ovarian granulosa cell tumors in mutant mice (43%) relative to mice carrying one wild-type copy of Bim1 (13%), all of whom also had mammary tumors
