homeostasis/metabolism
• after 18 hours of water deprivation, urine osmolality increases from 1860 to 2720 mosmol/ kg water in wild-type mice, but little increase is seen in tamoxifen-treated mutants
|
• after tamoxifen-induced deletion of Aqp2. osmolality of urine in mutants decreases from ~2000 mosmol/kg water to <500 mosmol/kg water by 4-5 days after tamoxifen injection and remains low at ~ 200 mosmol/kg water

renal/urinary system
• after 18 hours of water deprivation, urine osmolality increases from 1860 to 2720 mosmol/ kg water in wild-type mice, but little increase is seen in tamoxifen-treated mutants

• after tamoxifen-induced deletion of Aqp2. osmolality of urine in mutants decreases from ~2000 mosmol/kg water to <500 mosmol/kg water by 4-5 days after tamoxifen injection and remains low at ~ 200 mosmol/kg water
|
• dilatation of collecting ducts in the renal cortex and medulla is observed in kidneys 6 weeks after induction resulting from polyuria
|
• 6 weeks after induction, many kidneys show medullary atrophy

• seen in mice 6 weeks after tamoxifen induction
|
• seen in mice 6 weeks after tamoxifen induction
|
• after tamoxifen treatment, mice are severely polyuric, excreting ~10-fold greater fluid than controls
