Abstract:

Bone is a hard organ that makes up vertebrate endoskeleton, which plays a role in movement, support and protection for the body. The normal growth and development of bone is in the dynamic balance of bone metabolism, which is composed of bone formation and bone absorption. This balance is very important for maintaining bone mass and mineral homeostasis. In the process of bone growth and metabolism, there are many signaling pathways regulating bone formation and absorption, such as BMP (bone morphogenetic protein)/SMADs, TGF-β (transforming growth factor β), Wnt/β-catenin, OPG (osteoprotegerin)/RANKL (receptor activator of NF-κB ligand)/RANK (receptor activator of NF-κB), FGF (fibroblast growth factor) and Notch signaling pathway. These signaling pathways have complex regulatory mechanisms and are involved in the regulation of bone metabolism. In this review, we summarize the mechanism and research progress of signal pathways that play key regulatory roles in the process of animal bone metabolism, thereby laying a foundation for research in animal bone metabolism.

Key words: bone metabolism, signaling pathway, bone formation, bone resorption
