Dawson NJ, Hernandez-Gonzalez M, Monaghan P et al. · FASEB journal : official publication of the Federation of American Societies for Experimental Biology · 2025-09 · open access
Most animals experience abrupt developmental transitions involving major tissue remodeling, but the links with metabolic changes remain poorly understood. We examined ontogenetic changes in mitochondrial volume, oxidative capacity, oxygen consumption capacity, and anaerobic capacity across four…
- The emergence of chordin-like1 in gnathostomes may have contributed to the evolution of paired appendages.
Ermakova GV, Meyntser IV, Mugue NS et al. · Frontiers in cell and developmental biology · 2025-08 · open access
Genomic transformations during early vertebrate evolution, including two rounds of whole-genome duplication, laid the groundwork for the emergence of novel morphological features in jawed vertebrates. Among these innovations, paired appendages represent a major evolutionary milestone, whose…

Bonaccorsi di Patti MC, Meoni M, Toni M · Biomolecules · 2025-08 · open access
This study explores the structural transitions and aggregation behaviour of recombinant β- and γ-synucleins from five vertebrate species- Cyprinus carpio , Danio rerio , Xenopus laevis , Anolis carolinensis, and Homo sapiens -using thioflavin T fluorescence and circular dichroism spectroscopy, with…
- Evolutionary adaptations of TRPA1 thermosensitivity and skin thermoregulation in vertebrates.
Bertolesi GE, Heshami N, McFarlane S · iScience · 2025-08 · open access
Skin pigmentation contributes to thermoregulation in ectothermic vertebrates, while homeotherms rely on insulation such as feathers, fur, or blubber. Heat-sensing in vertebrates largely depends on transient receptor potential (TRP) channels, with TRPA1 showing evolutionary shifts in sensitivity.…

- Fertilization in the African clawed frog , Xenopus laevis , requires an egg-derived PLC to signal the fast block to polyspermy.
Komondor KM, Sharp KG, Carlson AE · microPublication biology · 2025-07 · open access
Fertilization in Xenopus laevis triggers calcium release and membrane depolarization to activate the fast block to polyspermy. This depolarization requires phospholipase C (PLC) activity, but the identity and origin of the PLC remained unclear. We previously reported that PLCZ1 , which encodes the…
- Differential bioconcentration and depuration of diphenhydramine in Xenopus laevis tadpoles and frogs.
Kocour Kroupová H, Steinbach C, Pech M et al. · Environmental pollution (Barking, Essex : 1987) · 2025-07
- Identification and Characterization of Static Craniofacial Defects in Pre-Metamorphic Xenopus laevis Tadpoles.
Jones E, Fonticella JM, McLaughlin KA · Journal of developmental biology · 2025-07 · open access
Craniofacial development is a complex, highly conserved process involving multiple tissue types and molecular pathways, with perturbations resulting in congenital defects that often require invasive surgical interventions to correct. Remarkably, some species, such as Xenopus laevis , can correct…
- Neurotoxic effects of Cis-bifenthrin on microbe-gut-brain axis: Disruption of neurolipid balance in Xenopus laevis.
Li M, Li C, He M et al. · Ecotoxicology and environmental safety · 2025-07 · open access
The neurotoxic effects of cis-bifenthrin (cis-BF) on amphibians and its molecular mechanisms are unclear despite its common presence in aquatic environments. In present study, female Xenopus laevis were subjected to a three-month treatment with environmentally relevant concentrations of 60 and 300…
- Could Horizontal Gene Transfer Explain 5S rDNA Similarities Between Frogs and Worm Parasites?
Gatto KP, Targueta CP, Vittorazzi SE et al. · Biomolecules · 2025-07 · open access
Horizontal gene transfer (HGT), the non-Mendelian transfer of genetic material between organisms, is relatively frequent in prokaryotes, whereas its extent among eukaryotes remains unclear. Here, we raise the hypothesis of a possible cross-phylum HGT event involving 5S ribosomal DNA (rDNA). A…
- Fluoxetine exposure alters behavior and morphology of Xenopus laevis tadpoles.
Cordero LJ, Smithwick Z, Cederlund B et al. · microPublication biology · 2025-07 · open access
This study exposed developing Xenopus tadpoles to the common antidepressant fluoxetine (FLU). Behaviorally, stage 46 control (0 nM) tadpoles significantly preferred white over black backgrounds, a potential anti-predation behavior, while tadpoles reared in 0.3 or 300 nM FLU did not display this…
- Insights into the evolution and regulation of hybrid internal-terminal exons from tropomyosin exon 9A in Xenopus laevis.
Méreau A, Lerivray H, Viet J et al. · Biochimie · 2025-07 · open access
Hybrid internal-terminal exons function as either internal or terminal exons. Their evolutionary origins remain unclear. Here, we investigate the phylogenetic origin and regulation of a hybrid exon, 9A9', in the TPM1 gene encoding tropomyosin alpha-1. We demonstrate that exon 9A9' was originally…

Sutton PJ, Mosqueda N, Brownlee CW · EMBO reports · 2025-05 · open access
Regulation of cell division orientation is a fundamental process critical to differentiation and tissue homeostasis. Microtubules emanating from the mitotic spindle pole bind a conserved complex of proteins at the cell cortex which orients the spindle and ultimately the cell division plane. Control…
