Secreted frizzled related proteins: Implications in cancers.
نویسندگان
چکیده
The Wnt (wingless-type) signaling pathway plays an important role in embryonic development, tissue homeostasis, and tumor progression becaluse of its effect on cell proliferation, migration, and differentiation. Secreted frizzled-related proteins (SFRPs) are extracellular inhibitors of Wnt signaling that act by binding directly to Wnt ligands or to Frizzled receptors. In recent years, aberrant expression of SFRPs has been reported to be associated with numerous cancers. As gene expression of SFRP members is often lost through promoter hypermethylation, inhibition of methylation through the use of epigenetic modifying agents could renew the expression of SFRP members and further antagonize deleterious Wnt signaling. Several reports have described epigenetic silencing of these Wnt signaling antagonists in various human cancers, suggesting their possible role as tumor suppressors. SFRP family members thus come across as potential tools in combating Wnt-driven tumorigenesis. However, little is known about SFRP family members and their role in different cancers. This review comprehensively covers all the available information on the role of SFRP molecules in various human cancers.

Beyond Wnt inhibition: new functions of secreted Frizzled-related proteins in development and disease.
The secreted Frizzled-related proteins (SFRPs) are a family of soluble proteins that are structurally related to Frizzled (Fz) proteins, the serpentine receptors that mediate the extensively used cell-cell communication pathway involving Wnt signalling. Because of their homology with the Wnt-binding domain on the Fz receptors, SFRPs were immediately characterised as antagonists that bind to Wnt...

Introduction: The involvement of secreted frizzled-related protein5 (SFRP5) and adiponectin, two important adipokines produced by adipocytes, in cardiovascular diseases demand further assessment. Therefore, in this study the relation of the adipokines and atherosclerosis was evaluated in Rat. Materials and methods: For the study, thirty male Wistar rats were divided into 2 groups (each group c...
متن کاملA pan-cancer analysis of secreted Frizzled-related proteins: re-examining their proposed tumour suppressive function
Secreted frizzled-related proteins (SFRPs), containing five family members (SFRPs 1-5) are putative extracellular Wnt inhibitors. Given their abilities to inhibit Wnt signalling, as well as the loss of SFRP1 in many cancers, this family is generally considered to be tumour suppressive. In this study we analyzed gene expression, promoter methylation and survival data from over 8000 tumour and no...

Cell–cell signalling: Frog frizbees
The recent discovery that Frizzled proteins are receptor for Wnts has been quickly followed by the identification of a secreted protein, Frzb, that is related to Frizzled, expressed by the Spemann organizer in frog embryos and can bind to and antagonize Wnt developmental signalling molecules.
