Sfrp-1 and sfrp-2 are expressed in overlapping and distinct domains during chick development
Secreted frizzled related proteins (Sfrps) are thought to bind and regulate Wnt activity through a cysteine rich domain that is highly similar to that of Frizzled receptors. To investigate possible roles for Sfrps in chick development, we have isolated partial cDNAs encoding Sfrp-1 and Sfrp-2 and have thoroughly characterized the expression patterns of both genes. Both sfrp-1 and sfrp-2 are exp...
متن کاملPlace- and time-dependent expression of mouse sFRP-1 during development of the cerebral neocortex
Wnts are a family of secreted proteins involved in multiple developmental mechanisms during nervous system development, including cell proliferation, cell migration, axon guidance and specification of cell positional information. We report here the expression of sFRP-1 mRNA, encoding a putative inhibitor of Wnt, in the developing mouse neocortex during the entire period when neurons for the neo...
متن کاملExpression pattern of mouse sFRP-1 and mWnt-8 gene during heart morphogenesis
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...
متن کاملTwo novel chick T-box genes related to mouse Brachyury are expressed in different, non-overlapping mesodermal domains during gastrulation.
The mouse Brachyury (T) gene plays critical roles in the genesis of normal mesoderm during gastrulation and in the maintenance of a functioning notochord. Abrogation of Brachyury (T) expression within the chordamesoderm of homozygous null mutants nevertheless spares anterior axis formation. An intriguing possibility to explain the preservation of anterior axis formation in these mutants would b...
متن کاملInvolvement of FrzA/sFRP-1 and the Wnt/frizzled pathway in ischemic preconditioning.
Phosphorylation and subsequent inactivation of glycogen synthase kinase (GSK)-3beta via the Akt/PI3-Kinase pathway during ischemic preconditioning (PC) has been shown to be cardioprotective. As FrzA/sFRP-1, a secreted antagonist of the Wnt/Frizzled pathway, is expressed in the heart and is able to decrease the phosphorylation of GSK-3beta in vitro on vascular cells, we examined its effect durin...
