Target Data

Function 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.
Gene References into Functions
  1. SFRP2 was downregulated in Choriocarcinoma and low expressed SFRP2 could promote migration, invasion, the epithelial-mesenchymal transition phenotype and stemness of Choriocarcinoma cells via Wnt/beta-catenin signaling PMID: 30396168
  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
  3. The content of the methylated SFRP2 gene in endometrial tissue of patients with hyperplastic processes higher than 20-25% allows relate these women to the risk group of EC development and dictates the need of intensive observation of such patients. PMID: 29949535
  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
  9. SFRP2 methylation is associated with colorectal cancer development. PMID: 26258809
  10. TET1 potently inhibited canonical Wnt/beta-catenin signaling by demethylating and upregulating two upstream antagonists of this pathway, SFRP2 and DKK1, which was associated with inhibition of EMT and cancer cell metastasis. PMID: 28851501
  11. SFRP2 could bind to locally present Wnt ligands and alter the balance of intracellular Wnt signaling to antagonize the canonical Wnt pathway in stem cells from the apical papilla. PMID: 28794794
  12. SFRP2 induction is remarkable in tumor stroma, with transcription mainly modulated by the nuclear factor-kappaB (NF-kappaB) complex, a property shared by several effectors of the DNA damage secretory program. PMID: 26751775
  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
  14. epigenetic silencing of Wnt antagonists was associated with gastric carcinogenesis, and concurrent hypermethylation of SFRP2 and DKK2 could be a potential marker for a prognosis of poor overall survival. PMID: 28152305
  15. SFRP2 enhances the adipogenic and neurogenic differentiation potentials of stem cells from apical papilla by up-regulating SOX2 and OCT4. PMID: 28244619
  16. SFRP2 is not only an agonist of Wnt pathway, but also a cancer promoting protein for lung cancer. PMID: 26323494
  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
  19. SFRP2 hypermethylation is associated with colorectal cancer. PMID: 27221916
  20. Silencing KDM2A, a histone demethylase and BCL6 co-repressor, de-repressed SFRP2 transcription by increasing histone H3K4 and H3K36 methylation at the SFRP2 promoter. PMID: 27074224

  23. Patients with Cytogenetically Normal Primary Acute Myeloid Leukemia and high sFRP2 expression had higher incidence of complete remission rate and better overall survival. PMID: 26517501
  24. A combination of GATA5 and SFRP2 methylation could be promising as a marker for the detection and diagnosis of colorectal cancers and adenomas. PMID: 25759530
  25. The distribution of Sfrp2 (and Sfrp1) in the eye is consistent with the idea that they modulate visual pathfinding and axon guidance. PMID: 25788689
