cardiovascular system
• in females
|
• females but not males show a significant increase in systolic blood pressure compared to sex-matched controls
• difference in females is seen when mice are on a high or low salt diet
• estrogen supplementation reduces systolic blood pressures in females to normal levels
|
• vasoconstriction in response to angiotensin II and endothelin I is enhanced in arterioles from females but not in those from males
• for both males and females baseline arteriole diameters are similar to controls
• supplementation with estrogen attenuates arteriole responses to angiotensin II in females but not in wild -type controls
|
homeostasis/metabolism
• decrease in 17beta-estradiol levels in females compared to female littermate controls
|
renal/urinary system
N |
• despite loss of expression in the kidneys, assays of gross kidney function (urine osmolality, serum creatinine, urine output) are normal
|
• increase in proximal tubular transport rates in females but not in males
|
reproductive system
• when females are continuously mated to wild-type males litter sizes are significantly smaller compared to crosses of wild-type females to wild-type males
|
muscle
• vasoconstriction in response to angiotensin II and endothelin I is enhanced in arterioles from females but not in those from males
• for both males and females baseline arteriole diameters are similar to controls
• supplementation with estrogen attenuates arteriole responses to angiotensin II in females but not in wild -type controls
