Secreted frizzled-related proteins (sFRPs) are secreted glycoproteins involved in neoplastic growth. Four hormones synthesized in the heart, namely vessel dilator, atrial natriuretic peptide (ANP), kaliuretic peptide (KP) and long-acting natriuretic peptide (LANP), have anticancer effects both in vitro and in vivo. These heart hormones were evaluated for their ability to inhibit sFRP-3, which i...
The Wnt genes encode a large family of secreted proteins that play a key role in embryonic development and tissue differentiation in many species (Rijsewijk et al., 1987; Nusse and Varmus, 1992). Genetic and biochemical studies have suggested that the frizzled proteins are cell surface receptors for Wnts (Vinson et al., 1989; Chan et al. , 1992; Bhanot et al., 1996; Wang et al., 1996). In paral...
Objective: To investigate the correlation between serum secretory frizzled-related protein 5 (SFRP-5) expression levels and insulin resistance glucolipid metabolism in patients with gestational diabetes mellitus (GDM). Methods: Baseline data were collected from 58 GDM 51 healthy controls who admitted Affiliated Hospital of Hebei University May 2020 to June 2022. sSTRA5 concentrations peripheral...
Polarization of node cells along the anterior-posterior axis of mouse embryos is responsible for left-right symmetry breaking. How node cells become polarized has remained unknown, however. Wnt5a and Wnt5b are expressed posteriorly relative to the node, whereas genes for Sfrp inhibitors of Wnt signaling are expressed anteriorly. Here we show that polarization of node cells is impaired in Wnt5a-...
In this issue of Clinical Cancer Research , Gumz et al. report on the loss of secreted frizzled-related protein-1 (sFRP-1) in clear cell renal cell carcinoma (RCC; ref. 1). sFRP-1 is a member of a family of proteins that bind Wnts and can inhibit Wnt signaling during embryonic development and in the adult homeostasis (2, 3). Inappropriate Wnt signaling is a well-established mechanism of oncogen...
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 ...
BACKGROUND The secreted frizzled related proteins (sFRP) are soluble proteins thought to interfere with the Wnt signaling. Our group previously demonstrated that one of these members, sFRP-1/FrzA, is strongly expressed during early phases of the vascularization process in embryonic vasculature and in the endothelium of arteries and capillaries in adults and modulated vascular cell proliferation...
The caudomedial margin of the medial pallium, known as the cortical hem, expresses several Wnt genes that have been shown to be crucial for cortical development. We examined the expression of members of the Frizzled (mFz) family of Wnt receptors and the Secreted Frizzled Related Protein (SFRP) family of Wnt inhibitors during telencephalic development. We found that mFz-5 and mFz-8 are specifica...
The use of short fiber reinforced polymers (SFRP) is increasing steadily in automotive and aerospace industry due to its mechanical properties and light weight. The mechanical and physical properties of SFRP depend on the geometrical characteristics of the reinforcing material. Under tensile stress various defects are induced in SFRP composites. X-ray computed tomography (XCT) is a non-destruct...
We investigated the expression of the secreted frizzled-related proteins (SFRPs) in keratoconus (KC) and control corneas. KC buttons (∼8 mm diameter) (n = 15) and whole control corneas (n = 7) were fixed in 10% formalin or 2% paraformaldehyde and subsequently paraffin embedded and sectioned. Sections for histopathology were stained with hematoxylin and eosin, or Periodic Acid Schiff's reagent. ...
