Identification of a Candidate CD5 Homologue in the Amphibian Xenopus laevis [PDF]

, 1995
We identified a novel T cell Ag in the South African clawed toad (Xenopus laevis) by a mAb designated 2B1. This Ag is present in relatively high levels on most thymocytes, approximately 65% of splenocytes, 55% of PBL, and 65% of intestinal lymphocytes ...

Evidence for functional convergence between LZTS2 and DYRK1A during craniofacial development

Developmental Dynamics, EarlyView.
Abstract Background Precise control of DYRK1A dosage is essential for embryonic development, including craniofacial morphogenesis. While LZTS2 is among the most consistently identified DYRK1A‐interacting proteins, its roles in embryonic development remain incompletely understood, and its potential contribution to craniofacial development has not been ...

Primary structure and evolutionary relationship between the adult alpha-globin genes and their 5'-flanking regions of Xenopus laevis and Xenopus tropicalis [PDF]

, 1988
To investigate the evolution of globin genes in the genus Xenopus, we have determined the primary structure of the related adult alpha I- and alpha II-globin genes of X. laevis and of the adult alpha-globin gene of X.

A maternal dorsoventral prepattern revealed by an asymmetric distribution of ventralizing molecules before fertilization in Xenopus laevis

Frontiers in Cell and Developmental Biology
The establishment of the embryonic dorsoventral axis in Xenopus occurs when the radial symmetry around the egg’s animal-vegetal axis is broken to give rise to the typical symmetry of Bilaterians.

Acquisition of Leftward Flow in Xenopus laevis

Bio-Protocol, 2013
In Xenopus, the left-right axis is established following an extracellular vectorial leftward flow driven by monocilia at the gastrocoel roof plate (GRP) during late gastrulation / neurulation (Schweickert et al., 2007).

Xenopus laevis Oocytes

, 2003
Xenopus oocytes are a versatile expression system particularly suited for membrane transporters and channels. Oocytes have little background activity and therefore offer a very high signal-to-noise ratio for transporter and channel characterization. This chapter provides an overview of the basic methods used for the analysis of membrane transporters in

Comparing Transcriptomic Responses to Chemicals Across Six Species Using the EcoToxChip RNASeq Database

Environmental Toxicology and Chemistry, EarlyView.
Abstract The EcoToxChip project includes RNA‐sequencing data from experiments involving model (Japanese quail, fathead minnow, African clawed frog) and ecological (double‐crested cormorant, rainbow trout, northern leopard frog) species at multiple life stages (whole embryo and adult) exposed to eight chemicals of environmental concern known to perturb ...

The Melanogenic System of Xenopus laevis.

Archives of Histology and Cytology, 1998
Melanin pigments in lower vertebrates are often found in locations other than the skin, thus forming an extracutaneous pigmentary system of unknown function. The cellular and biochemical structure of this system is still poorly characterized. This paper deals with the ultrastructural and biochemical features of the melanogenic system of Xenopus laevis.

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Notch activates Wnt-4 signalling to control medio-lateral patterning of the pronephros [PDF]

, 2009
Previous studies have highlighted a role for the Notch signalling pathway during pronephrogenesis in the amphibian Xenopus laevis, and in nephron development in the mammalian metanephros, yet a mechanism for this function remains elusive.
