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

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

STUDIES ON THE OVULATION IN XENOPUS LAEVIS

open access: bronzeThe KITAKANTO Medical Journal, 1968
The quantjtative bioasaay test for human chorionic gonadotropin, employing the femaleXnnosps laevis toad, has proven its clinical usefulness in a series of 372 patients. Other biological and immunological pregnancy tests are also investigated simultaeneously for comparative purposes.1) 249 cases of normal pregnancy, using Xenopus pregnancy test, were ...

Genome evolution in the allotetraploid frog Xenopus laevis

open access: yesNature, 2016
To explore the origins and consequences of tetraploidy in the African clawed frog, we sequenced the Xenopus laevis genome and compared it to the related diploid X. tropicalis genome. We characterize the allotetraploid origin of X.

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

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

Xenopus laevis neural stem progenitor cells exhibit a transient metabolic shift toward glycolysis during spinal cord regeneration [PDF]

open access: yesFrontiers in Cell and Developmental Biology
Spinal cord injury (SCI) results in severe disruption of communication between the brain and body, causing motor, sensory, and autonomic dysfunctions. While SCI in mammals leads to permanent impairment due to limited regenerative capacity, certain non ...

A maternal dorsoventral prepattern revealed by an asymmetric distribution of ventralizing molecules before fertilization in Xenopus laevis [PDF]

open access: yesFrontiers in Cell and Developmental Biology
The establishment of the embryonic dorsoventral axis in Xenopus occurs when the radial symmetry around the egg’s animal-vegetal axis is broken to give rise to the typical symmetry of Bilaterians.

Early Head Specification in Xenopus laevis [PDF]

open access: yesThe Scientific World Journal, 2003
The head represents the most dorsal and anterior extent of the body axis. In Xenopus, the progressive determination of the head is an extremely complex process involving the activation and localized antagonism of a number of interdependent intracellular ...

Establishment of the body condition score for adult female Xenopus laevis.

open access: yesPLoS ONE, 2023
The assessment of animals' health and nutritional status using a Body Condition Score (BCS) has become a common and reliable tool in lab-animal science. It enables a simple, semi-objective, and non-invasive assessment (palpation of osteal prominences and

Morphological, acoustic and genetic identification of a reproducing population of the invasive African clawed frog Xenopus laevis (Anura, Pipidae) recently discovered in Belgium [PDF]

open access: yesZooKeys, 2023
Using external morphology of adults and tadpoles, osteology from high-resolution microcomputed tomography, vocalization analysis, and DNA sequence data, the identity of a reproducing Belgian population of invasive Xenopus at the current northernmost edge
