Endocrine regulation of longitudinal bone growth.
Longitudinal growth is primarily influenced by the GH-IGF-I axis, which is a mixed endocrine-paracrine-autocrine system. Further, classical hormones such as thyroxine, glucocorticosteroids and sex steroids play a role, as well as primarily paracrine systems. In the GH-IGF-I axis, seven disorders can be differentiated: (1) GH deficiency; (2) GHR defects; (3) defects in the GH signal transduction...
متن کاملResistance exercise and bone turnover in elderly men and women.
PURPOSE This investigation examined the effect of 6 months of high- or low-intensity resistance exercise (REX) on bone mineral density (BMD) and biochemical markers of bone turnover in adults aged 60-83 yr. METHODS Sixty-two men and women (68.4 +/- 6 yr) were stratified for strength and randomly assigned to a control (CON, N = 16), low-intensity (LEX, N = 24), or high-intensity (HEX, N = 22) ...
متن کاملRegulation of Bone Metabolism
Bone is formed through the processes of endochondral and intramembranous ossification. In endochondral ossification primary mesenchymal cells differentiate to chondrocytes and then are progressively substituted by bone, while in intramembranous ossification mesenchymal stem cells (MSCs) differentiate directly into osteoblasts to form bone. The steps of osteogenic proliferation, differentiation,...
متن کاملEndocrine functions of bone in mineral metabolism regulation.
Given the dramatic increase in skeletal size during growth, the need to preserve skeletal mass during adulthood, and the large capacity of bone to store calcium and phosphate, juxtaposed with the essential role of phosphate in energy metabolism and the adverse effects of hyperphosphatemia, it is not surprising that a complex systems biology has evolved that permits cross-talk between bone and o...
متن کاملADRA2A is involved in neuro-endocrine regulation of bone resorption
Adrenergic stimulation is important for osteoclast differentiation and bone resorption. Previous research shows that this happens through β2-adrenergic receptor (AR), but there are conflicting evidence on presence and role of α2A-AR in bone. The aim of this study was to investigate the presence of α2A-AR and its involvement in neuro-endocrine signalling of bone remodelling in humans. Real-time ...
