xGCNF, a nuclear orphan receptor is expressed during neurulation in Xenopus laevis
Nuclear orphan receptors are DNA binding proteins that share the domain structure of the nuclear hormone receptor superfamily, although ligands are unknown. We have identified an orphan receptor in Xenopus laevis and named it xGCNF based on its high degree of sequence homology to the previously described murine germ cell nuclear factor (mGCNF). In gel-electrophoresis mobility shift analysis exp...
متن کاملAnteroposterior patterning and organogenesis of Xenopus laevis require a correct dose of germ cell nuclear factor (xGCNF)
The germ cell nuclear factor of Xenopus laevis (xGCNF; NR6A1) is a nuclear orphan receptor that is predominantly expressed during neurula and late tailbud stages. As a strategy to analyze the role of xGCNF in embryogenesis, we have induced a gain of function by overexpression of full-length (fl) GCNF and a functional inhibition by a dominant-negative (dn) GCNF. Early events of embryogenesis inc...
متن کاملThe germ cell nuclear factor is required for retinoic acid signaling during Xenopus development
The germ cell nuclear factor (GCNF, NR6A1) is a nuclear orphan receptor that functions as a transcriptional repressor and is transiently expressed in mammalian carcinoma cells during retinoic acid (RA) induced neuronal differentiation. During Xenopus laevis development, the spatiotemporal expression pattern of embryonic GCNF (xEmGCNF) suggests a role in anteroposterior specification of the neur...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Overexpression of the secreted factor Mig30 expressed in the Spemann organizer impairs morphogenetic movements during Xenopus gastrulation
The Spemann organizer secretes several antagonists of growth factors during gastrulation. We describe a novel secreted protein, Mig30, which is expressed in the anterior endomesoderm of the Spemann organizer. Mixer-inducible gene 30 (Mig30) was isolated as a target of Mixer, a homeobox gene required for endoderm development. The Mig30 gene encodes a secreted protein containing a cysteine-rich d...
