Overview of Gene Research
Sost, encoding sclerostin, is an osteocyte-derived negative regulator of bone formation [1,4]. It inhibits the canonical Wnt signaling pathway, a key pathway in bone metabolism [1]. Sost is of great importance in maintaining bone homeostasis and skeletal integrity [2]. Genetic models, such as transgenic and knockout mice, have been crucial for studying Sost [1].
In mice with wear-particle-induced cranial osteolysis, SOST gene suppression stimulated osteocyte Wnt/β-catenin signaling, preventing bone resorption and attenuating particle-induced osteolysis. Blocking SOST also protected against bone loss and deformation caused by titanium particles [3]. In a glucocorticoid-associated osteonecrosis of the femoral head (GA-ONFH) rat model, SOST knockout ameliorated the incidence of osteonecrosis and improved bone metabolism. Sclerostin derived from osteocytes impaired osteogenesis and angiogenesis via inhibiting the Wnt pathway in GA-ONFH [2].
In conclusion, Sost plays a vital role in bone metabolism by regulating the Wnt signaling pathway. Studies using SOST knockout mouse models have provided insights into its role in diseases like particle-induced osteolysis and GA-ONFH, helping to understand the mechanisms of bone-related diseases and potentially guiding the development of new therapeutic strategies.
