Obtaining Xenopus laevis Embryos

Cold Spring Harbor Protocols, 2020
The embryos of the African clawed frog, Xenopus laevis, are a powerful substrate for the study of complex fundamental biological and disease mechanisms in neurobiology, physiology, molecular biology, cell biology, and developmental biology. A simple and straightforward technique for generating a large number of developmentally synchronized embryos is ...

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.

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

Overland movement in African clawed frogs (Xenopus laevis): a systematic review

PeerJ, 2016
African clawed frogs (Xenopus laevis) are often referred to as ‘purely aquatic’ but there are many publications which suggest extensive overland movements.

A NuRD Complex from Xenopus laevis Eggs Is Essential for DNA Replication during Early Embryogenesis

Cell Reports, 2018
Summary: DNA replication in the embryo of Xenopus laevis changes dramatically at the mid-blastula transition (MBT), with Y RNA-independent random initiation switching to Y RNA-dependent initiation at specific origins.

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.

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

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.

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.

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.
