  • 功能：
    Soluble frizzled-related proteins (sFRPS) function as modulators of Wnt signaling through direct interaction with Wnts. They have a role in regulating cell growth and differentiation in specific cell types. SFRP2 may be important for eye retinal development and for myogenesis.
  • 基因功能参考文献：

    2. Results show that SFRP2 and SFRP4 typically associate with a poor prognosis of cancer patients concomitant with the expression of genes associated with epithelial-to-mesenchymal transition. SFRP2 and 4 are likely derived from the tumor stroma, and thus tend to increase in tumors as compared to normal tissues. PMID: 28218291

    4. Findings demonstrated that SFRP2 was downregulated in pituitary corticotroph adenomas. SFRP2 appears to act as a tumor suppressor in Cushing's disease by regulating the activity of the Wnt signaling pathway. PMID: 29620167
    5. SFRP2 was down-regulated in the accelerated and blast phase of CML, whereas, the levels of WNT1, WNT3 and WNT5A were up-regulated in the accelerated and blast phase of CML. Overexpression SFRP2 inhibited proliferation, promoted apoptosis and activated the WNT pathway. PMID: 29704505
    6. Methylation of SFRP2 gene may promote the invasiveness of non-small cell lung cancer cells through ZEB1 and MMP9 signaling. PMID: 29320940
    7. the differences in SFRP2 promotor methylation observed between colorectal cancer (CRC)patients and healthy individuals by both assays were statistically significant (p<0.001). Our findings, although limited by the small sample size, do not support the use of the MSRH assay for CRC screening in stool. PMID: 28777432
    8. augments Wnt3a-mediated beta-catenin signalling in dermal papilla cells, especially in beard dermal papilla cells PMID: 26914690

    13. down-regulated in ICU-acquired weakness and mice with inflammation-induced muscle atrophy; possibly establishes a positive feedback loop enhancing TGF-beta1-mediated atrophic effects in inflammation-induced atrophy PMID: 27661566

    17. DKK1 (dickkopf-1) and SFRP2 (secreted frizzled-related protein 2) were the targets of miR-522 in hepatocellular carcinoma PMID: 26960688
    18. the demethylation of SFRP2 gene appeared to inhibit nuclear retention of a key Wnt signaling factor, b-catenin, in osteosarcoma (OS) cell lines. Together, these data suggest that SFRP2 may function as an OS invasion suppressor by interfering with Wnt signaling, and the methylation of SFRP2 gene may promote pathogenesis of OS PMID: 26628297
