FrzA, a secreted frizzled related protein, induced angiogenic response.
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...
متن کاملimmunohistochemical analysis and role of secreted frizzled-related protein-4 in polycystic ovary-induced rat
objective: the role of wnt signaling and its antagonist; secreted frizzled related protein type 4 (sfpr4) was reported in rodent ovarian follicular development. this study examines immunolocalization of sfrp4 in ovaries of polycystic ovary (pco) rat model and evaluates its role in follicular growth arrest and its premature differentiation. materials and mathods: pco was induced with daily admin...
متن کاملInhibition of secreted frizzled-related protein 5 improves glucose metabolism.
Elucidating the role of secreted frizzled-related protein 5 (SFRP5) in metabolism and obesity has been complicated by contradictory findings when knockout mice were used to determine metabolic phenotypes. By overexpressing SFRP5 in obese, prediabetic mice we consistently observed elevated hyperglycemia and glucose intolerance, supporting SFRP5 as a negative regulator of glucose metabolism. Acco...
متن کاملFritz: a secreted frizzled-related protein that inhibits Wnt activity
Signaling molecules of the Wnt gene family are involved in the regulation of dorso-ventral, segmental and tissue polarity in Xenopus and Drosophila embryos. Members of the frizzled gene family, such as Drosophila frizzled-2 and rat frizzled-1, have been shown encode Wnt binding activity and to engage intracellular signal transduction molecules known to be part of the Wnt signaling pathway. Here...
متن کاملSphingosine-1-phosphate protects proliferating endothelial cells from ceramide-induced apoptosis but not from DNA damage-induced mitotic death.
Because of the central role of the endothelium in tissue homeostasis, protecting the vasculature from radiation-induced death is a major concern in tissue radioprotection. Premitotic apoptosis and mitotic death are two prevalent cell death pathways induced by ionizing radiation. Endothelial cells undergo apoptosis after radiation through generation of the sphingolipid ceramide. However, if mito...
