Osteoclast and mechanical stimuli
WebOsteoclasts activation is initiated by humoral stimuli and mechanical loading and, therefore, several factors can contribute to the development of osteoporosis. Among them, impairment of Runt-related transcription factor 2 (Runx2) activity might obstruct the differentiation of osteoblast by promoting the formation of adipose cells from … WebAug 1, 2015 · 1.

Did you know?
WebBMP-2 and Wnt16 mRNA levels were downregulated by mechanical instability and this was rescued by GSK-3β inhibition. Osteoclast numbers were decreased significantly after 3 days of GSK-3β inhibition, which correlated with enhanced OPG mRNA expression. This was accompanied by decreased serum levels of TRAP5b on days 3 and 5. Web14. Explain the meaning of homeostasis as applied to the living organism. All homeostatic control mechanisms have three components. A receptor that responds to environmental changes (stimuli) and a control center that assesses those changes and produces a response by activating the effector. Most homeostatic control systems are negative …
