skeleton
• females mice have 1.5 times more osteoclasts on bone surface compared to wild-type females
|
• osteoclasts are resistant to estrogen induced apoptosis due to a failure to produce fas-ligand
|
• females, but not males, have decreased density of the femur
|
osteoporosis
(
J:127179
)
• 12 week old female but not male mice have 1.6 fold loss of trabecular bone volume that is indicative of osteoporosis
• loss of bone volume is not increased upon ovariectomy
• treatment with estrogen fails to rescue the bone loss
|
• increased mineral apposition rate in female mice
|
• increased bone formation rate in female mice
|
• females have increased rates of bone resorption as measured by eroded surface per bone surface
|
