Heart regeneration in adult Xenopus tropicalis after apical resection

Cell & 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.

Molecular Characterization of Thyroid Hormone Receptors (TRs) and their Responsiveness to T3 in Microhyla fissipes [PDF]

, 2018
To explore and enrich the molecular mechanisms of thyroid hormone receptors (TRs) in the metamorphosis of amphibians, the cDNA sequences of TR alpha and TR beta in Microhyla fissipes were cloned and characterized.

QuickProt: A Fast and Accurate Homology‐Based Protein Annotation Tool for Non‐Model Organisms to Advance Comparative Genomics

Molecular Ecology Resources, Volume 26, Issue 2, February 2026.
ABSTRACT The rapid growth of genome sequencing has outpaced the development of efficient annotation tools, especially for species lacking transcriptome data. To address this challenge, we present QuickProt, a fast, accurate and user‐friendly homology‐based protein annotation tool.

The behaviour–performance continuum: how does individual variation in locomotor abilities relate to behaviour?

Biological Reviews, Volume 101, Issue 1, Page 486-518, February 2026.
ABSTRACT A series of terminological, technical, conceptual, and statistical challenges present themselves when trying to study correlations between measures of performance abilities (what an animal can do) and behavioural traits (what an animal chooses to do).

Identification of a novel conserved mixed-isoform B56 regulatory subunit and spatiotemporal regulation of protein phosphatase 2A during Xenopus laevis development [PDF]

, 2007
Background Wnt signaling is a key regulator of development and tumorigenesis. Protein phosphatase 2A (PP2A), which consists of a catalytic C, a structural A, and a regulatory B subunit, plays diverse roles in Wnt signaling through its B56 subunits.

The NLS3 Motif in TPX2 Regulates Spindle Architecture in Xenopus Egg Extracts

Cytoskeleton, Volume 83, Issue 1, Page 29-39, January 2026.
ABSTRACT A bipolar spindle composed of microtubules and many associated proteins functions to segregate chromosomes during cell division in all eukaryotes, yet both spindle size and architecture vary dramatically across different species and cell types.

Frog origins: inferences based on ancestral reconstructions of locomotor performance and anatomy [PDF]

, 2016
Frogs are the most species-rich and ecologically diverse group of amphibians and are characterized by a unique body plan including long legs, elongated ilia, and fused caudal vertebrae.

Comparative analysis of Xenopus tropicalis and Xenopus laevis vitellogenin gene sequences

Nucleic Acids Research, 1982
Analysis of cDNA clones synthesized from vitellogenin mRNA of X. tropicalis revealed three different types of cDNA clones, i.e. A, A* and B. A and A* clones have a sequence divergence of about 6% and are both related to X. laevis vitellogenin cDNAs of subgroup A1 as well as A2 with a sequence divergence of 6-9%.

Functional Screening of NDUFAF6 Variants in Knockout Cells and Complementary Computational Analysis

Journal of Clinical Laboratory Analysis, Volume 40, Issue 1, January 2026.
We established an ATP‐based functional screening system in NDUFAF6 knockout cells to evaluate the pathogenicity of gene variants associated with mitochondrial dysfunction. Our results highlight the limitations of in silico predictions and underscore the necessity of experimental validation for accurate variant interpretation.

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

BMC 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 ...
