產品詳情

  • 產品描述：
    大鼠硬骨素(SOST)酶聯免疫試劑盒（CSB-EL022415RA）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿樣本中的SOST含量。SOST是一個重要靶點。它編碼的骨硬化蛋白可抑制成骨細胞活性，影響骨形成。目前對其的研究聚焦于揭示調控骨代謝的機制，旨在通過干預SOST，為骨質疏松等骨疾病開發新療法，改善骨密度和骨質量。試劑盒檢測范圍為18.75 pg/mL-1200 pg/mL，適用于骨骼發育、骨修復模型構建、代謝性疾病動物實驗等科研場景，能夠對藥物干預、基因編輯或病理狀態下SOST的表達水平變化進行動態分析，為骨生物學研究提供可靠工具。本品僅用于科研，不用于臨床診斷，產品具體參數及操作步驟詳見產品說明書。

靶點詳情

  • 功能：
    Negative regulator of bone growth that acts through inhibition of Wnt signaling and bone formation.
  • 基因功能參考文獻：
    1. alleviated the osteogenic differentiation of ectomesenchymal stem cells (EMSCs), and LNGFR enhanced the osteogenic differentiation of EMSCs by decreasing SOST PMID: 29226516
    2. TNF-alpha might mediate alveolar bone loss via inducing expression of osteocytic RANKL and sclerostin in type 1 diabetes rats with periodontitis PMID: 29240821
    3. These data suggest that sclerostin plays an important role in the bone remodeling of tooth movement. PMID: 28081119
    4. a direct correlation between attenuated SOST expression and an increase in the osteogenic potential of UMR-106 cells, is reported. PMID: 27233518
    5. In conclusion, naringin could prevent progress of disuse osteoporosis in rats, which may be mediated by increased periostin expression and subsequently inhibition of sclerostin and activation of Wnt/beta-catenin signaling pathways. PMID: 26541456
    6. Scl-Ab increased osteoblast surface and bone formation, indicating direct bone anabolic effects, whereas TE reduced osteoclast surface with minimal effect on bone formation, indicating antiresorptive effects PMID: 25359699
    7. Data indicate that sclerostin (SOST) gene expression is negatively regulated by histone deacetylase HDAC5 and positively by class I HDACs. PMID: 25012661
    8. The results suggest that Sost mRNA expression in metaphyseal bone responds to mechanical unloading in an opposite direction to that observed in diaphyseal cortical bone. PMID: 23337040
    9. Pharmacologic inhibition of sclerostin with Scl-Ab has no impact on articular cartilage remodeling in rats with posttraumatic osteoarthritis. PMID: 23233270
    10. Confocal immunofluorescence tiling imaging revealed the spatio-temporal distributions of osterix and sclerostin in femurs from 3-day-old, 2-week-old and 4-week-old rats to be reciprocally exclusive at the tissue level. PMID: 22766096
    11. The proportion of sclerostin-positive osteocytes in cortical bone was significantly higher. PMID: 22174402
    12. Insulin-deficiency in insulin-dependent diabetes mellitus decreases osteoblastogenesis associated with inhibition of Wnt signaling through the increased expression of Sost and Dkk1 and the inhibition of Akt activation. PMID: 21567076
    13. These results indicate that sclerostin inhibition by treatment with a sclerostin antibody increased bone formation, bone mass, and bone strength in aged male rats. PMID: 20641040
    14. SOST regulation may play a role in mediating PTH action in bone PMID: 15946907
    15. The anabolic effects of parathyroid hormone (PTH) are in line with the fall of SOST mRNA and protein in all the three bone segments examined; the rise of bone turnover supports a negative role of SOST in bone formation. PMID: 17549589
    16. SOST expression in osteocytes of adult bone and its inhibition by PTH is mediated by MEF2A, C, and D transcription factors controlling the SOST bone enhancer. PMID: 17696759
    17. Modulation of sclerostin levels appears to be a finely tuned mechanism by which osteocytes coordinate regional and local osteogenesis in response to increased mechanical stimulation, perhaps via releasing the local inhibition of Wnt/Lrp5 signaling PMID: 18089564
