Interference with the microenvironmental growth support is an attractive therapeutic strategy for repressing metastatic tumor growth. Bone is a highly dynamic tissue that is continuously remodeled by bone resorption and subsequent bone formation. Growth factors supporting bone metastatic growth are released especially during bone resorption. Differently from most other tissues, drugs that can l...

Estrogen deficiency induced bone loss is associated with increased bone turnover in rats and humans. The respective roles of increased bone turnover and altered balance between bone formation and bone resorption in mediating estrogen deficiency-induced cancellous bone loss was investigated in ovariectomized rats. Ovariectomy resulted in increased bone turnover in the distal femur. However, canc...

BACKGROUND Subclinical thyroid dysfunction might influence a bone health. We evaluated whether subclinical hypothyroidism adversely affects bone health including bone mineral density (BMD), level of vitamin D, and bone turnover status in patients with hip fracture. METHODS We evaluated 471 patients aged 50 years or older, who underwent hip fracture surgeries. BMD, level of vitamin D, bone tur...

Saito et al. (1) reported that raloxifene (RAL) suppressed bone turnover and increased the quantitative ultrasound (QUS) parameter, speed of sound (SOS) of the calcaneus in hemodialysis postmenopausal women with type 2 diabetes or without type 2 diabetes. Baseline bone turnover markers like serum cross-linked N-terminal telopeptides of type I collagen (NTX) and bone-specific alkaline phosphatas...

Bones are constantly remodelled to cope with the body's calcium requirements and to repair microscopic damage. The entire skeleton is replaced every 10 years in adults, and around 10% of the skeleton is involved in bone remodelling at any one time.

Assessing bone turnover is a key diagnostic tool in the global management of chronic kidney disease-mineral and bone disorder (CKD-MBD). Since bone biopsy is invasive and cannot be repeated in clinical practice and because bone histomorphometry is less available due to the lack of specialized laboratories, we will focus on potential biomarkers used to assess and monitor bone turnover. After bri...

Abnormalities of bone turnover are commonly observed in patients with chronic kidney disease (CKD), and the low-turnover bone disease is considered to be associated with low serum parathyroid hormone (PTH) levels and skeletal resistance to PTH. Indoxyl sulfate (IS) is a representative uremic toxin that accumulates in the blood of patients with CKD. Recently, we have reported that IS exacerbates...

Vascular calcification (VC) occurs frequently in chronic kidney disease, contributing to cardiovascular mortality. Numerous risk factors have been identified, including renal osteodystrophy and bone turnover, with low turnover as a main determinant. Other reports support high turnover as a factor in VC. Calcimimetics, which lower serum parathyroid hormone, and parathyroidectomy each prevented V...

Compact bone makes up approximately 80% of the human skeletal mass. This study examines the effect of estrogen deficiency on compact bone turnover and associated geometrical structural adaptation over a 31-month period in a large animal model. Twenty-seven skeletally mature sheep were divided into control (n = 16) and ovariectomy group (OVX, n = 11). Animals were administered five different flu...
