homeostasis/metabolism
• in tamoxifen-treated mice
|
• greater than 2-fold in tamoxifen-treated mice due to reduced intestinal absorption
• however, kidney function is normal
|
• tamoxifen-treated mice fail to exhibit a change in phosphorus in response to nicotinamide unlike similarly treated control mice
|
digestive/alimentary system
• after 10 week, tamoxifen-treated mice exhibit a 2-fold increase in focal phosphate content compared with similarly treated control mice
|
• tamoxifen-treated mice exhibit reduced intestinal absorption of phosphorus compared with similarly treated control mice
• tamoxifen-treated mice fail to exhibit a change in phosphorus in response to nicotinamide unlike similarly treated control mice
• tamoxifen-treated mice exhibit reduced sodium dependent intestinal phosphate transport in the jejunum and ileum compared with similarly treated control mice
• however, tamoxifen-treated mice exhibit normal calcium and sodium-independent phosphate transport
|
renal/urinary system
• in tamoxifen-treated mice
|
• greater than 2-fold in tamoxifen-treated mice due to reduced intestinal absorption
• however, kidney function is normal
|
respiratory system
• tamoxifen-treated mice develop calcification nodules in the lungs (pulmonary alveolar microlithiasis) unlike similarly treated control mice
