Objective: The role of osteoprotegerin (OPG) and its receptor activator of nuclear factor kappaB legend (RANKL) in the regulation of bone in humans remain unclear. We examined the sex-specific associations of serum OPG, RANKL, and their ratio with bone mineral density (BMD) in older adults.
Design: Participants were 681 community-dwelling adults, ages 45-90 years, who had serum OPG and RANKL measured and bone density scans in 1988-1991, with follow-up scans 5 and/or 10 years later.
Methods: Analyses were sex-specific; women using and not using estrogen were evaluated separately. Cross-sectional analyses used multivariable regression models; longitudinal analyses used repeated measures mixed effects models.
Results: In cross-sectional analyses, age- and weight-adjusted serum OPG levels were significantly positively associated with BMD at the lumbar spine in men, and at the femoral neck, total hip, and lumbar spine in women using estrogen, but not in non-users of estrogen. RANKL concentrations were significantly and inversely associated with BMD in men only, and at the total hip. Neither OPG nor RANKL was significantly associated with bone loss. Results for the RANKL/OPG ratio were the same as those for RANKL alone.
Conclusions: These results suggest a modulatory effect of both endogenous and exogenous sex hormones on the biologic interaction of OPG, RANKL, and bone.

Purpose: Aromatase inhibitor-associated musculoskeletal symptoms (AIMSS) are the most common adverse effects experienced by breast cancer patients. This scoping review aimed to systematically synthesize the predictors/risk factors and outcomes of AIMSS in patients with early-stage breast cancer.
Methods: A systematic search was conducted in PubMed, Web of Science, EMBASE, CINAHL, and the China National Knowledge Internet (CNKI) from inception to December 2024 following the scoping review framework proposed by Arksey and O'Malley (2005).
Fluoride Exposure Modulates Skeletal Development and Mineralization in Zebrafish Larvae.

The presence of high levels of fluoride (F) in groundwater is a major issue worldwide. Although F is essential for healthy teeth and bones, excessive exposure can cause fluorosis or F toxicity. This condition primarily affects the hard tissues due to their high F retention capacity.

To clarify the roles and mechanisms of adipokine chemerin in exercise-induced bone improvements in type 2 diabetes mellitus (DM) mice and mice fed on high fat diet (HFD). DM mice were established by HFD+streptozotocin injection, exogenous chemerin was supplemented prior to running, and found that exogenous chemerin reversed 6-week exercise-induced improvements in cancellous bone parameters in DM mice. While adipose-specific chemerin knockout improved microstructure and mass of cancellous bone in HFD mice and further increased exercise-induced bone improvements, accompanied with promoted osteogenesis and inhibited osteoclasis represented as the changes of RANKL, M-CSF, Runx2, Osterix, OPG, ALP and CTSK.

Background: Systemic lupus erythematosus requires glucocorticoids for management. This study investigates how glucocorticoids influence bone in a SLE mouse model, focusing on bone mineral density (BMD), microstructure, and remodeling markers.
Methods: MRL/lpr and C57BL/6 mice were administered dexamethasone or saline as a control for 4-weeks.

Objective: This study aimed to evaluate bone remodeling in gingival crevicular fluid (GCF) during canine distalization in obese individuals and compare it to that in normal-weight individuals. Additionally, the orthodontic tooth movement rates of obese individuals were measured and compared with those of normal-weight individuals.
Methods: Thirty-six patients (18 obese and 18 normal-weight) aged 12-18 years who were candidates for maxillary first premolar extraction for Angle Class II malocclusion were included in the study.
