Effects of testosterone and high‐dose anabolic steroids on orthodontic‐induced bone remodeling and root resorption: An animal study

Journal of Periodontology, EarlyView.
Abstract Background This study investigates the impact of disruptions in testosterone levels on bone remodeling, root resorption, and periodontal ligament (PDL) during orthodontic tooth movement (OTM) in a pubertal male rat model. Methods Testosterone deficiency was induced through orchiectomy, and the anabolic‐androgenic steroid (AAS, testosterone ...

Osteoporosis and polymorphisms of osteoprotegerin gene in postmenopausal women – a pilot study

Rheumatology, 2016
Objectives: Osteoprotegerin (OPG) has an important role in bone remodeling, and it has been proposed that the OPG gene might be a candidate gene for osteoporosis predisposition.

Osteoprotegerin is a new regulator of inflammation and angiogenesis in proliferative diabetic retinopathy [PDF]

, 2003
Osteoprotegerin (OPG) is a novel regulator of endothelial cell function, angiogenesis, and vasculogenesis. We correlated expression levels of OPG with those of the angiogenic and inflammatory factors vascular endothelial growth factor (VEGF) and monocyte

Alterations in brain metabolites in rats with experimental periodontitis: A metabolomic approach

Journal of Periodontology, EarlyView.
Abstract Background Periodontitis (PD) is a chronic inflammatory disease with systemic effects. Emerging evidence suggests a link between periodontal inflammation and neurological changes, but the biochemical mechanisms in key brain regions, such as the hippocampus and amygdala, remain unclear.

Estradiol replacement attenuates alendronate‐associated adverse effects on alveolar bone repair in ovariectomized rats

Journal of Periodontology, EarlyView.
Abstract Background Sodium alendronate (ALN) is widely used to treat postmenopausal osteoporosis, but both estrogen deficiency and antiresorptive therapy may impair alveolar bone repair after tooth extraction. A clinically relevant but insufficiently explored scenario involves estrogen‐deficient individuals receiving hormone replacement therapy (HRT ...

Osteoprotegerin in Prostate Cancer Bone Metastasis [PDF]

Cancer Research, 2005
Abstract Osteoprotegerin (OPG), a critical regulator of osteoclastogenesis, is expressed by prostate cancer cells, and OPG levels are increased in patients with prostate cancer bone metastases. The objective of this study was to investigate the effects of OPG overexpression on prostate cancer cells and prostate cancer/bone cell ...

Staging concept for aging management: Definition, mechanism, and coping strategies

VIEW, EarlyView.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...

A Novel Small Molecule Which Increases Osteoprotegerin Expression and Protects Against Ovariectomy-Related Bone Loss in Rats

Frontiers in Pharmacology, 2019
The ratio of osteoprotegerin (OPG) to the receptor activator of NF-κB ligand (RANKL) is a key determinant in the regulation of bone metabolism. The study was performed to screen novel anti-osteoporotic drugs regulating OPG/RANKL ratio and evaluate their ...
