Bone Microstructure Osteoporosis Trabecular Bone EFFECT OF VITAMIN K2 ON 3-D TRABECULAR MICROARCHITECTURE IN OVARIECTOMIZED RATS
Introduction : Two types of vitamin K occur in nature: vitamin K1 (phylloquinone, 2-methyl-3-phytyl-1,4-naphthoquinone), which is derived from plants, and vitamin K2 (menaquinones), a series of vitamers with multiisoprene units at the 3-position. Vitamin K2 activates osteoblasts to enhance calcification, acts as a coenzyme of γ-carboxylase for the Gla protein, and is also reported to inhibit bo...
متن کاملComparison of the Effect of Vitamin K2 and Risedronate on Trabecular Bone in Glucocorticoid-Treated Rats: A Bone Histomorphometry Study
PURPOSE To compare the effect of vitamin K(2) and risedronate on trabecular bone in glucocorticoid (GC)-treated rats. MATERIALS AND METHODS Forty-eight Sprague-Dawley female rats, 3 months of age, were randomized by the stratified weight method into 5 groups according to the following treatment schedule: age-matched control, GC administration, and GC administration with concomitant administra...
متن کاملVitamin K2 and Bone Health
During the last 20 years, the main clinical effects of vitamin K2 on bone homeostasis have been investigated in both indirect and direct vitamin K treatment regimens. This chapter is mainly based on randomized clinical trials (RCT) lasting for more than 1 year. As for vitamin K1 (phylloquinone, indirect treatment) and vitamin K2 (menaquinone MK‐4 and MK‐7 direct treatment), respectively, the cl...
متن کاملVitamin K2 and Bone Quality
Vitamin K is a cofactor required for post-translational gamma-carboxylation of vitamin K-dependent proteins, including coagulation and anti-coagulation factors; osteocalcin (OC), essential for bone metabolism; and matrix Gla proteins (MGP), an inhibitor of artery calcification. In addition to activation of OC, vitamin K2 induces collagen accumulation in the bone matrix. The principle effects of...
متن کاملVitamin K2 in bone metabolism and osteoporosis.
This article covers in vitro, in vivo, and human data on the positive effect of vitamin K2 on osteoporosis. Data is available on vitamin K2 for osteoporosis caused by a number of conditions, including postmenopausal osteoporosis, Parkinson's disease, biliary cirrhosis, stroke, and drug-induced osteoporosis. The activity of vitamin K2 involves both an increase in the bone-building process and a ...
