Heart regeneration in adult Xenopus tropicalis after apical resection

open access: yesCell & Bioscience, 2017
Background Myocardium regeneration in adult mammals is very limited, but has enormous therapeutic potentials. However, we are far from complete understanding the cellular and molecular mechanisms by which heart tissue can regenerate.

Decreased cold‐sensing function of the transient receptor potential channel TRPM8 from tailed amphibians

open access: yesFEBS Open Bio, Volume 16, Issue 8, Page 1477-1490, August 2026.
Despite frogs avoiding low temperatures, examination of four salamander species revealed that none avoided cold and all possessed cold tolerance. Functional analysis of TRPM8, a cold sensor, showed that all salamander TRPM8s had lost their cold sensitivity.

Two Routes to Land: Genomic Underpinnings of Parallel Aerial Egg Deposition in Aquatic Old‐World Pila and New‐World Pomacea (Ampullariidae)

open access: yesAdvanced Science, Volume 13, Issue 48, 28 August 2026.
Comparative genomics of Gondwana‐diverged Pila and Pomacea reveals parallel evolution of aerial oviposition. Convergent chromosomal rearrangements reshape regulatory landscapes within topologically associating domains. Lineage‐specific gene family expansions and viral‐derived perivitelline proteins (PV1) underpin desiccation resistance.

Effects of Timing of Microbial Exposure on Microbiome Assembly and Amphibian Immune Development

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
We used a novel amphibian gnotobiotic system to investigate how disruptions to the microbiome during critical developmental periods influence microbial assembly and the development of immunity. We found that antimicrobial treatments of embryos and subsequent introduction to microbes at different developmental stages altered microbiome assembly ...

Xenopus tropicalis Agote

open access: yes
Xenopus tropicalis (Gray, 1864) (Fig. 12C) MATERIAL EXAMINED. — Togo • 4 ♀; Agoté; MNHN-RA-2006.2172-2175. DESCRIPTION. — Medium to large frog (SVL 40-56 mm ♀), with flattened body. Snout rounded. Head very small, wider than long (HW 26-29% SVL; HL 21-26% SVL). Very small eyes and eyelids (EL 1.4-1.6 mm diameter); a very small subocular tentacle, about

Ontogeny and Homology of the Shoulder Joint and Forelimb Muscles in Frogs and Toads (Lissamphibia: Anura)

open access: yesJournal of Morphology, Volume 287, Issue 8, August 2026.
The ontogenetic development, innervation, and morphology of the shoulder joint and forelimb muscles were investigated in 11 anuran species. The results reveal largely conserved splitting patterns of the dorsal and ventral pre‐muscle masses, alongside interspecific variation in muscle subdivision and morphology.

Characterization of histone genes isolated from Xenopus laevis and Xenopus tropicalis genomic libraries.

open access: yes, 1982
Using a cDNA clone for the histone H3 we have isolated, from two genomic libraries of Xenopus laevis and Xenopus tropicalis, clones containing four different histone gene clusters. The structural organization of X.

Exploring nervous system transcriptomes during embryogenesis and metamorphosis in Xenopus tropicalis using EST analysis

open access: yesBMC Genomics, 2007
Background The western African clawed frog Xenopus tropicalis is an anuran amphibian species now used as model in vertebrate comparative genomics. It provides the same advantages as Xenopus laevis but is diploid and has a smaller genome of 1.7 Gbp ...

Maternal Wnt/β-catenin signaling coactivates transcription through NF-κB binding sites during Xenopus axis formation. [PDF]

open access: yes, 2012
Maternal Wnt/β-Catenin signaling establishes a program of dorsal-specific gene expression required for axial patterning in Xenopus. We previously reported that a subset of dorsally expressed genes depends not only on Wnt/β-Catenin stimulation, but also ...
