We have revisited the actions of hormones from the anterior pituitary, notably TSH, on bone and bone cells. Traditionally, the bone loss in hyperthyroidism has been attributed solely to elevated circulating levels of thyroid hormones. The role of TSH, which is reduced in all forms of hyperthyroidism, as well as during thyroxine suppressive therapy for thyroid cancer, has never been investigated. We found that haploinsufficiency of the TSH receptor in mice led to bone loss with...

Objective: Bisphenol A (BPA) exposure may promote obesity, but its effect on bone mineral density (BMD) has not been reported in humans. In the present study, we aimed to examine the complex interplay between BPA exposure, fat mass, fat-free mass, serum estradiol, leptin, osteocalcin levels and BMDs in a group of premenopausal women.Methods: A total of 246 Chinese premenopausal women aged 20 years and older with regular menstrual cycles were investigated...
