Cooperation behavior of fore‐ And hindlimbs during jumping in Rana dybowskii and Xenopus laevis
Ecology and Evolution, 2021 Frogs are characterized by their outstanding jumping ability, depending on the rapid extension of hindlimbs to propel their bodies into air. A typical jumping cycle could be broken into four phases: preparation, takeoff, flight, and landing. Considerable

Characterization of Xenopus tissue inhibitor of metalloproteinases-2: a role in regulating matrix metalloproteinase activity during development. [PDF]
PLoS ONE, 2012 Frog metamorphosis is totally dependent on thyroid hormone (T3) and mimics the postembryonic period around birth in mammals. It is an excellent model to study the molecular basis of postembryonic development in vertebrate.

Microinjection of Xenopus Laevis Oocytes [PDF]
Journal of Visualized Experiments, 2009 Microinjection of Xenopus laevis oocytes followed by thin-sectioning electron microscopy (EM) is an excellent system for studying nucleocytoplasmic transport. Because of its large nucleus and high density of nuclear pore complexes (NPCs), nuclear transport can be easily visualized in the Xenopus oocyte.

Synuclein Analysis in Adult Xenopus laevis
International Journal of Molecular Sciences, 2022 The α-, β- and γ-synucleins are small soluble proteins expressed in the nervous system of mammals and evolutionary conserved in vertebrates. After being discovered in the cartilaginous fish Torpedo californica, synucleins have been sequenced in all vertebrates, showing differences in the number of genes and splicing isoforms in different taxa. Although

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.

Lipids of Xenopus laevis Spermatozoa [PDF]
Development, Growth & Differentiation, 1992 Xenopus laevis sperm lipid composition has been studied. The cholesterol content of Xenopus spermatozoa is 194 μ/mg DNA. Their content of glycolipids and phospholipids (measured as inorganic phosphorus) is respectively 40 and 27 μ/mg DNA. The phospholipid pattern is quite homogeneous and all the principal molecular species are present.

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.

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 ...

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 InvasionsThe 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.

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 ...
