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...

Circadian Genes Are Expressed during Early Development in Xenopus laevis

BACKGROUND Circadian oscillators are endogenous time-keeping mechanisms that drive twenty four hour rhythmic changes in gene expression, metabolism, hormone levels, and physical activity. We have examined the developmental expression of genes known to regulate circadian rhythms in order to better understand the ontogeny of the circadian clock in a vertebrate. METHODOLOGY/PRINCIPAL FINDINGS In...

Anteroposterior 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...

Dopamine D2 receptor regulation of the dopamine transporter expressed in Xenopus laevis oocytes is voltage-independent.

Presynaptic dopamine D2 receptors (D2Rs) regulate dopamine transporter (DAT) activity in the brain. A potential mechanism was suggested by the observations that somatodendritic D2R activation produces hyperpolarization and the velocity of DAT expressed in Xenopus laevis oocytes varies with changes in membrane potential. To investigate whether D2R regulation of DAT function is voltage-dependent,...

Expression pattern of insulin receptor mRNA during Xenopus laevis embryogenesis

We have identified a member of the insulin receptor (InsR)/insulin-like growth factor-1 receptor (IGF-1R) family. The Xenopus insulin receptor (Xe-InsR) is present as a maternal 6.6 kb transcript. Northern blot analysis reveals the presence of this transcript until the mid-blastula transition (MBT), when levels decrease. At neurulation, two distinct transcripts of 6.6 and 7.7 kb are detected, b...
