The finding that fat regulates bone metabolism was viewed as an indication that bone might regulate some aspects of energy metabolism in a feedback loop. The search that started nine years ago for a bone-derived hormone that regulates energy metabolism first took a convoluted path through the identification of a modifier gene. Once this hormone, osteocalcin, was identified, it became clear that...

BACKGROUND Bone metabolism assessment requires the determination of bone mass and quality. The bone metabolism was assessed with the modified bone scintigraphy using 99mTc-MDP. The elaboration of radioisotopic method and program allowed for the assessment of bone metabolism, index of bone metabolism assay and definition of its normal values range with the possibility of clinical application. ...

This literature review presents data on the influence of serotonin metabolism bone tissue. The mechanisms by which affects formation and resorption bone, depending site synthesis (central or peripheral), as well cells receptor subtypes that are activated, have been considered. A number issues for further research highlighted, in particular, dose-response relationship side effects during chronic...

Currently several studies are being carried out on various properties of mesenchymal stem cells (MSCs)however there are a few investigations about drug metabolizing properties of these cells. The aim of thisstudy was to measure the key factors involved in drug metabolism in human bone marrow MSCs. For thispurpose, cellular glutathione (GSH), glutathione Stransferase (GSTs) and...

It is well established that diabetes can be detrimental to bone health, and its chronic complications have been associated with an increased risk of osteoporotic fracture. However, there is growing evidence that the skeleton plays a key role in a whole-organism approach to physiology. The hypothesis that bone may be involved in the regulation of physiological functions, such as insulin sensitiv...

Obesity, diabetes, and osteoporosis are major public health concerns. Current estimates indicate that the US population consists of 25% obese, 30% diabetic and prediabetic, and, among the elderly, 50% of all osteoporotic individuals. Mechanistically, these pathologies share several features including common regulators of bone homeostasis and energy metabolism. Peroxisome proliferator-activated ...
