Xenopus Hybrids Provide Insight Into Cell and Organism Size Control

Frontiers in Physiology, 2018
Determining how size is controlled is a fundamental question in biology that is poorly understood at the organismal, cellular, and subcellular levels. The Xenopus species, X. laevis and X. tropicalis differ in size at all three of these levels.

Development of the proepicardium in Xenopus laevis [PDF]

Developmental 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 ...

Heat-shock mediated overexpression of HNF1β mutations has differential effects on gene expression in the Xenopus pronephric kidney. [PDF]

, 2012
The transcription factor HNF1B, encoded by the TCF2 gene, plays an important role in the organogenesis of vertebrates. In humans, heterozygous mutations of HNF1B are associated with several diseases, such as pancreatic β-cell dysfunction leading to ...

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]

Aquatic 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.

RMND5 from Xenopus laevis is an E3 ubiquitin-ligase and functions in early embryonic forebrain development. [PDF]

PLoS ONE, 2015
In Saccharomyces cerevisiae the Gid-complex functions as an ubiquitin-ligase complex that regulates the metabolic switch between glycolysis and gluconeogenesis.

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

Nature 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 ...

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

Genomics 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).

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

PLoS 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.

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Use of monoclonal antibodies to study alloreactivity and T cell development in Xenopus [PDF]

, 1993
This study investigated T-cell surface antigenic changes in the spleen of Xenopus following in vivo and in vitro allergenic challenge, using novel mouse monoclonal antibodies (mAb's) against all T cells (CDS), the putative ɑβ-T cell receptor (TCR), the ...
