Revealing the trophic role of the invasive African clawed frog Xenopus laevis through combined analysis of stable isotopes and heavy metals in a Mediterranean stream from central Chile [PDF]

open access: yesAquatic Invasions
The African clawed frog Xenopus laevis is invasive on four continents, and is recognized as one of the invasive amphibians that generates the greatest impacts in the ecosystems it invades.

Regulation of ALF promoter activity in Xenopus oocytes. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:In this report we evaluate the use of Xenopus laevis oocytes as a matched germ cell system for characterizing the organization and transcriptional activity of a germ cell-specific X. laevis promoter.

Biomonitoring of the genotoxic potential (micronucleus assay) and detoxifying activity (EROD induction) in the River Dadou (France), using the amphibian Xenopus laevis [PDF]

open access: yes, 2004
Within the framework of a general survey of the water quality of the river Dadou (Tarn, France), different physicochemical parameters were measured and an inventory of the fish population was made along the water course, around the Rassisse dam.With the ...

Development of the proepicardium in Xenopus laevis [PDF]

open access: yesDevelopmental Dynamics, 2008
AbstractThe proepicardium (PE) is an embryonic progenitor cell population, which provides the epicardium, the majority of the cardiac interstitium, the coronary vasculature and possibly some cardiomyocytes. Recent studies have documented (1) the presence of bilaterally paired PE anlagen in several vertebrates, and (2) species‐specific differences in ...

Identifying direct targets of transcription factor Rfx2 that coordinate ciliogenesis and cell movement

open access: yesGenomics Data, 2014
Recently, using the frog Xenopus laevis as a model system, we showed that the transcription factor Rfx2 coordinates many genes involved in ciliogenesis and cell movement in multiciliated cells (Chung et al., 2014).

interleukin-11 induces and maintains progenitors of different cell lineages during Xenopus tadpole tail regeneration

open access: yesNature Communications, 2017
Xenopus laevis tadpoles have maintained their ability to regenerate various organs. Here, the authors show that interleukin-11 is necessary for organ regeneration, by inducing and maintaining undifferentiated progenitors across cell lineages during ...

Gene Structure Analysis of Chemokines and Their Receptors in Allotetraploid Frog, Xenopus laevis

open access: yesFrontiers in Genetics, 2022
Chemokines, relatively small secreted proteins, are involved in cell migration and function in various biological events, including immunity, morphogenesis, and disease.

Xenopus and Zebrafish Annotation in the UniProt Knowledgebase (UniProtKB) [PDF]

open access: yes, 2009
The African clawed frog Xenopus laevis and the zebrafish Danio rerio have both proved to be good model organisms for studying early vertebrate cellular and developmental biology.

The Melanogenic System of Xenopus laevis.

open access: yesArchives 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.
