Geographical Variation in Thermal Adaptation of the Asiatic Toad (Bufo gargarizans)

Integrative Zoology, EarlyView.
Northern and southern populations of Bufo gargarizans exhibit coordinated divergence in thermal preference, resting metabolic rate, and TRPM4 temperature sensitivity along a climatic gradient. ABSTRACT Thermal adaptation in animals can manifest in multiple dimensions, yet few studies have integrated behavioral, physiological, and molecular perspectives

Metabolomic approach for identifying and visualizing molecular tissue markers in tadpoles of Xenopus tropicalis by mass spectrometry imaging

Biology Open, 2016
In developmental and cell biology it is crucial to evaluate the dynamic profiles of metabolites. An emerging frog model system using Xenopus tropicalis, whose genome sequence and inbred strains are available, is now ready for metabolomics investigation ...

Retinoic acid-activated Ndrg1a represses Wnt/β-catenin signaling to allow Xenopus pancreas, oesophagus, stomach, and duodenum specification. [PDF]

PLoS ONE, 2013
How cells integrate multiple patterning signals to achieve early endoderm regionalization remains largely unknown. Between gastrulation and neurulation, retinoic acid (RA) signaling is required, while Wnt/β-catenin signaling has to be repressed for the ...

Chromosome‐Level Genome Assembly of Strauchbufo raddei and Multi‐Omic Insights Into Drought Adaptation

Integrative Zoology, EarlyView.
ABSTRACT Understanding how amphibians adapt to terrestrial and arid environments is important for elucidating vertebrate terrestrialization. In this study, we present the first chromosome‐level, high‐quality genome assembly of Strauchbufo raddei, constructed using PacBio HiFi long‐read sequencing and Hi‐C scaffolding. The assembled genome is 4.47 Gb in

Sox9 and Vasa Gene Expression During Gonadal Differentiation in Larvae of the Urodele Amphibian Ambystoma mexicanum

Acta Zoologica, EarlyView.
ABSTRACT The study of genes involved in sexual differentiation, as Vasa and Sox9, is of great importance, as they serve as specific markers for the germline and the male differentiation pathway, respectively. This study characterized using immunofluorescence the expression of the Vasa and Sox9 genes and laminin during gonadal differentiation in larvae ...

Cerebral Ventriculomegaly With Abnormality of the Aqueduct of Sylvius: A Case Series

Clinical Genetics, EarlyView.
Genetic testing leads to a diagnostic rate of ~30% in a fetal cohort with cerebral ventriculomegaly where the neuropathological examination revealed a stenosis or atresia of the aqueduct of Sylvius. ABSTRACT Fetal cerebral ventriculomegalies are brain anomalies with potentially poor neurodevelopmental prognosis.

Modeling of Genome-Wide Polyadenylation Signals in Xenopus tropicalis

Frontiers in Genetics, 2019
Alternative polyadenylation (APA) is an important post-transcriptional modification event to process messenger RNA (mRNA) for transcriptional termination, transport, and translation.

Ploidy‐dependent modulation of DNA replication kinetics in Xenopus

The FEBS Journal, EarlyView.
Using an interspecies replication system with Xenopus frog species of different ploidy levels, we investigated how DNA replication adapts to polyploidization. While replication was slower in tetraploid than in diploid nuclei, dodecaploid nuclei unexpectedly replicated faster than tetraploid nuclei. Our findings show that increasing genome size does not

Thyroid hormone receptor subtype-specific function in controlling organ-specific developmental timing and rate during Xenopus development

Frontiers in Endocrinology
Thyroid hormone (T3) is essential for vertebrate development as animals fail to develop into adults in the absence of T3. T3 is particularly critical for postembryonic development.
