Comparative Evaluation of Genotoxicity of Captan in Amphibian Larvae (Xenopus laevis and Pleurodeles waltl) Using the Comet Assay and the Micronucleus Test [PDF]
, 2006 Captan (N-trichloromethylthio-4-cyclohexene-1,2-dicarboximide) is a fungicide used to inhibit the growth of many types of fungi on plants used as foodstuffs.

Patterns of tubb2b Promoter-Driven Fluorescence in the Forebrain of Larval Xenopus laevis
Frontiers in Neuroanatomy, 2022 Microtubules are essential components of the cytoskeleton of all eukaryotic cells and consist of α- and β-tubulin heterodimers. Several tissue-specific isotypes of α- and β-tubulins, encoded by distinct genes, have been described in vertebrates.

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.

Phosphorylation by Cdk1 increases the binding of Eg5 to microtubules in vitro and in Xenopus egg extract spindles. [PDF]
PLoS ONE, 2008 BACKGROUND:Motor proteins from the kinesin-5 subfamily play an essential role in spindle assembly during cell division of most organisms. These motors crosslink and slide microtubules in the spindle.

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

Stage-specific histone modification profiles reveal global transitions in the Xenopus embryonic epigenome. [PDF]
, 2011 Vertebrate embryos are derived from a transitory pool of pluripotent cells. By the process of embryonic induction, these precursor cells are assigned to specific fates and differentiation programs.

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

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.

Studies on Fertilization in Xenopus laevis [PDF]
Biology of Reproduction, 1974 In Xenopus laevis, the fertilization rate increases gradually between the fallopian tube and the ovisac without any marked local rise correlated with a special jelly layer. This suggests that the diameter of the jelly coat, rather than a factor restricted to one or another jelly layer, is important in sperm capacitation in vivo.

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.
