Abstract UNLABELLED Bone collagen maturation may be important for anti-fracture efficacy as the reduction in risk is only partly explained by a concomitant increase in BMD during anti-resorptive therapy. Different treatments caused diverse profiles in bone collagen degradation products, which may have implications for bone quality. INTRODUCTION The aim of the present study was to […]

Abstract The objective of this work was to investigate whether collagen degradation products in protein extract from joints could provide quantitative information on cartilage damage. Osteoarthritis (OA) was surgically induced in rat knee joints. Joints were isolated 7, 14 and 28 days after surgery for protein extraction and histology. C-terminal telopeptide of type III collagen […]

Abstract UNLABELLED We investigated whether the age of the bones endogenously exerts control over the bone resorption ability of the osteoclasts, and found that osteoclasts preferentially develop and resorb bone on aged bone. These findings indicate that the bone matrix itself plays a role in targeted remodeling of aged bones. INTRODUCTION Osteoclasts resorb aging bone […]

Abstract Collagen characteristics contribute to bone biomechanical properties. Yet, few studies have analyzed the independent contributions of bone mineral density (BMD) and post-translational modifications of type I collagen to whole bone strength. Thus, the aim of this study was to determine the relative contributions of BMD and both enzymatic and non-enzymatic collagen crosslink concentration to […]

Abstract BACKGROUND Maintenance of the structural and functional integrity of the skeleton is a critical function of a continuous remodeling driven by highly associated processes of bone resorption and synthetic activities driven by osteoclasts and osteoblasts, respectively. Acceleration of bone turnover, accompanied with a disruption of the coupling between these cellular activities, plays an established […]

Abstract We recently showed that increased urinary excretion of the cross-linked, nonisomerized form of the C-telopeptide of collagen type I (alphaalphaCTX) could be a sensitive indicator of the presence of bone metastases in breast cancer patients. The present study was sought to investigate (a) the localization of alphaCTX epitopes in the proximity of a bone […]

Abstract The present study was sought to assess the relative use of eight biomarkers for the detection of bone metastases in cancer forms frequently spreading to the skeleton. Participants were 161 patients with either breast, prostate, or lung cancer. The presence and extent of bone metastases was assessed by imaging techniques (computer tomography and/or magnetic […]
