High molecular weight hyaluronic acid alleviates ovariectomy-induced bone loss in mice.

ABSTRACT:

Background

The rapid decline in ovarian function associated with menopause promotes osteoclast differentiation and increases bone resorption, disrupting of bone homeostasis and increasing the risk of osteoporosis. Hyaluronic acid (HA) is a polysaccharide ubiquitously present in the connective tissues. Recent reports indicate that high-molecular-weight HA (HMW-HA) promotes osteoblast proliferation, enhances alkaline phosphatase activity and mineral deposition, and promotes the expression of bone differentiation markers, such as Runx2 and osteocalcin. HMW-HA also inhibits the expression of the receptor activator of nuclear factor kappa-B ligand (RANKL) in osteoblasts. These results suggest that HMW-HA may be an effective therapeutic agent against postmenopausal osteoporosis. Therefor
