Osteoporosis and cardiovascular disease (CVD) share common risk factors and pathophysiological mechanisms, raising concerns about the cardiovascular implications of sclerostin inhibition. Romosozumab, a monoclonal antibody that targets sclerostin, is effective in increasing bone mineral density (BMD) and reducing fracture risk. However, evidence suggests that sclerostin inhibition may adversely affect vascular calcification, potentially increasing the risk of myocardial infarction (MI) and stroke.

Osteogenesis imperfecta (OI) is a fairly common generalized connective disorder characterized by low bone mass, bone deformities and impaired bone quality that predisposes affected individuals to musculoskeletal fragility. Periodontal ligament (PDL)-alveolar bone and PDL-cementum entheses' roles under OI conditions during physiological loading and orthodontic forces remain largely unknown. In addition, bisphosphonates (e.

A defect in the canonical Wnt-β-catenin pathway may lead to reduced bone strength and increased fracture risk. Sclerostin is a key inhibitor of this pathway by binding to low-density lipoprotein (LDL) receptor-related protein , thereby reducing bone formation. The effectiveness of romosozumab, a human monoclonal antibody that binds sclerostin and prevents this inhibitory effect, has been questioned in patients with inactivating genetic variants in or .

Objective: To elucidate the mechanisms underlying diabetic osteoporosis, we conducted a comprehensive histological examination of the femora of Spontaneously Diabetic Torii-Lepr (SDT-fa/fa) rats, an established model of obesity-related type 2 diabetes.
Materials And Methods: Femora from 12 30-week-old male SDT-fa/fa rats and age-matched Sprague-Dawley (SD) rats (controls) were used for detailed histochemical analyses, including tartrate-resistant acid phosphatase (TRAP), cathepsin K, alkaline phosphatase (ALP), phosphoethanolamine/ phosphocholine phosphatase 1 (PHOSPHO1), dentin matrix protein (DMP)-1, matrix extracellular phosphoglycoprotein (MEPE), sclerostin, osteocalcin staining, silver impregnation, von Kossa staining, and micro-computed tomography (CT).
Results: Micro-CT and hematoxylin-eosin staining demonstrated significantly reduced trabecular bone volume in the femoral metaphyses of SDT-fa/fa rats.

Background: The bone-vascular axis plays a key role in the pathogenesis of vascular calcification (VC) in patients with chronic kidney disease (CKD). Understanding and managing the role of the bone-vascular axis in CKD-mineral and bone disorder (CKD-MBD) is critical for preventing and treating associated complications, including osteoporosis, arterial calcification, and cardiovascular diseases. This study aimed to comprehensively summarize the role of bone metabolism markers in uremic VC.
