Ubiquitin-proteasome system regulation of bone remodeling in postmenopausal osteoporosis (opens in new tab)

Postmenopausal osteoporosis (PMOP) is associated with declining estrogen levels, and this hormonal deficiency alters the physiological balance between bone formation and resorption. Substantial evidence indicates that protein homeostasis disorders play a significant role in the pathological process of PMOP. As the core system regulating protein homeostasis, the ubiquitin-proteasome system exerts crucial regulatory effects on bone metabolism under estrogen-deficient conditions. Abnormal activi...
