homeostasis/metabolism
• induction of Cyp1A1 and Cyp1a2 by TCDD is absent from the liver, in addition Cyp1a2 constitutive expression is decreased
• hepatic induction of Slc2a1, Aldoa, and Hmox1 by CoCl2, which mimics physiological hypoxia, is variably reduced

reproductive system
• incomplete development of alveoli probably secondary to impaired ovarian function as tissue transplanted into athymic nude mice develops normally
• contain fewer primordial follicles but similar numbers of primary and preantral/antral follicles compared to controls
• however estrus cycle and the levels of estradiol and progesterone are similar to controls
• fewer primordial follicles compared to controls
• average litter size is 4 +/- 2 pups

endocrine/exocrine glands
• incomplete development of alveoli probably secondary to impaired ovarian function as tissue transplanted into athymic nude mice develops normally
• contain fewer primordial follicles but similar numbers of primary and preantral/antral follicles compared to controls
• however estrus cycle and the levels of estradiol and progesterone are similar to controls
• fewer primordial follicles compared to controls
• 60% of dams can not support their pups and surviving pups are smaller compared to pups nursed by homozygous dams lacking Cre expression (controls)
