Bones of the skeleton are constantly remodeled through bone resorption by cells called osteoclasts and bone formation by cells called osteoblasts. Both cell types are under multi-hormone control. New research findings demonstrate that bone formation by osteoblasts is negatively regulated by the hormone leptin, which is secreted by adipocytes and acts through the leptin receptor in the central n...

Vitamin K contributes to bone health, probably through its role as cofactor in the carboxylation of osteocalcin. Intervention studies in adults have demonstrated that markedly higher osteocalcin carboxylation is obtained by intakes of vitamin K well above the current recommended dietary intake. However, the relationship between increased vitamin K2 intake and enhanced osteocalcin carboxylation ...

Objective: The purpose of the present study was to evaluate the possible association between the serum levels of undercarboxylated osteocalcin (ucOC) and osteoprotegerin (OPG) in patients with knee osteoarthritis (OA). Methods: Twenty patients (10 men and 10 women) diagnosed to have knee OA, and twenty healthy subjects of matching age, sex, and BMI as a control group, were enrolled in this stud...

BACKGROUND We aimed to investigate the diagnostic utility of osteocalcin (OC), undercarboxylated osteocalcin (ucOC), and alkaline phosphatase (ALP) in pre- and postmenopausal women for femoral neck, L1-4, and L2-4 bone mineral density (BMD) values by taking into consideration their age, body mass index (BMI), and menopausal status. METHODS Premenopausal (N=40) and postmenopausal cases (N=42) ...

CONTEXT Undercarboxylated osteocalcin (ucOC) modulates insulin secretion and sensitivity in mice, and higher ucOC is associated with lower prevalence of diabetes in men. The influence of ucOC distinct from other markers of bone turnover on incidence of cardiovascular events is unclear. PARTICIPANTS Community-dwelling men aged 70-89 years resident in Perth, Western Australia. MAIN OUTCOME ME...
