OBJECTIVE Vascular calcification is a common pathobiological process which occurs among the elder population and in patients with diabetes and chronic kidney disease. Osteoprotegerin, a secreted glycoprotein that regulates bone mass, has recently emerged as an important regulator of the development of vascular calcification. However, the mechanism is not fully understood. The purpose of this st...
We recently reported the downregulation of osteoprotegerin expression in primary colorectal carcinoma and its significant association with aggressive oncogenic behavior, which suggest that this process contributes to colorectal carcinoma development and progression. In this study, we used immunohistochemical staining to evaluate osteoprotegerin expression in 81 colorectal liver metastasis tissu...
background: pregnancy associated osteoporosis (pao) can lead to serious difficulties such as fragility fractures, elongated back pain and height loss in affected women. soluble receptor activator of nuclear factor-kappa b ligand (srankl) to osteoprotegerin (opg) ratio is chosen as a bone metabolism equation in many bone diseases characterized by bone resorption, such as post-menopausal osteopor...
conclusions we confirmed that serum opg concentrations reduce in obese children. however, no correlation was identified between opg and insulin resistance. opg levels are not meaningful in the diagnosis of nafld in children with obesity. methods this was a prospective, cross-sectional, controlled study that was conducted in the department of pediatrics at bagcilar training and research hospital...
Patients treated for primary adrenal insufficiency (PAI) are at risk of steroid over-replacement, which may affect their skeleton. The study was aimed to investigate the effect of steroid substitution on serum osteoprotegerin and receptor activator of nuclear factor kappa-beta ligand (RANKL) levels in relation to bone mineral density (BMD) in PAI. Eighty patients (mean age 47.2±14.5 years, mean...
Circulating and myocardial expressions of receptor activator of nuclear factor-κb ligand and osteoprotegerin are activated in heart failure; however, it remains to be determined their pathophysiological roles on left ventricular structure and function in interaction with renin-angiotensin system. We conducted experiments using 8-week-old osteoprotegerin(-/-) mice and receptor activator of nucle...
Osteoprotegerin (OPG) is a kind of tumor necrosis factor, which is related to bone metabolism and vascular calcification. The increase of Osteoprotegerin concentration in serum is related to cardiovascular diseases in humans. The purpose of this study was to figure out the relevance between osteoprotegerin in serum and carotid calcification. Serum OPG concentrations were compared in 145 patient...
Diabetes, as a serious metobolic disorder, poses global threat to human health. It is estimated that over 50 million individuals are already affected by diabetes. Currently, diabetes-related osteoporosis has been a research hotspot due to its high incidence rate in older individuals. Osteoprotegerin, as an important protein for the prevention of osteoporosis, has been proven to be key to the su...
BACKGROUND Recent experimental and epidemiological studies have suggested that osteoprotegerin, a key regulator in bone metabolism, may be involved in vascular calcification and atherosclerosis. Our aim was to reliably quantify the associations of osteoprotegerin concentration and incidence of first-ever cardiovascular disease outcomes in the general population. METHODS Using the electronic d...
