Developmental Dynamics, EarlyView.Abstract Background Environmental influence is critical for embryogenesis but is significantly under‐appreciated under lab conditions, which are not typically designed to robustly test environmental variability. Here, we report environmental effects on the developmental phenotype of zebrafish lacking the transcription factor Grainyhead‐like 3 (grhl3 ...

Identification of a Candidate CD5 Homologue in the Amphibian Xenopus laevis [PDF]
, 1995 We identified a novel T cell Ag in the South African clawed toad (Xenopus laevis) by a mAb designated 2B1. This Ag is present in relatively high levels on most thymocytes, approximately 65% of splenocytes, 55% of PBL, and 65% of intestinal lymphocytes ...

Biomonitoring of the genotoxic potential (micronucleus assay) and detoxifying activity (EROD induction) in the River Dadou (France), using the amphibian Xenopus laevis [PDF]
, 2004 Within the framework of a general survey of the water quality of the river Dadou (Tarn, France), different physicochemical parameters were measured and an inventory of the fish population was made along the water course, around the Rassisse dam.With the ...

Relating cell shape and mechanical stress in a spatially disordered epithelium using a vertex-based model [PDF]
Mathematical Medicine and Biology: A Journal of the IMA, dqx008
(2017), 2016 Using a popular vertex-based model to describe a spatially disordered planar epithelial monolayer, we examine the relationship between cell shape and mechanical stress at the cell and tissue level. Deriving expressions for stress tensors starting from an energetic formulation of the model, we show that the principal axes of stress for an individual ...

A GC-MS/Single-Cell Method to Evaluate Membrane Transporter Substrate Specificity and Signaling
Frontiers in Molecular Biosciences, 2021 Amino acid transporters play a vital role in metabolism and nutrient signaling pathways. Typically, transport activity is investigated using single substrates and competing amounts of other amino acids.

Developmental Dynamics, EarlyView.Abstract Background Freshwater salinization is an emerging stressor in amphibian populations, and embryonic stages are most vulnerable. To better understand the variation in embryonic osmoregulation, we challenged embryos of two phylogenetically diverse anuran species, Xenopus laevis and Lithobates (Rana) sylvaticus, along a gradient of non‐lethal ...

Transcriptionally inactive oocyte-type 5S RNA genes of Xenopus laevis are complexed with TFIIIA in vitro [PDF]
, 1987 An extract from whole oocytes of Xenopus laevis was shown to transcribe somatic-type 5S RNA genes approximately 100-fold more efficiently than oocyte-type 5S RNA genes.

Developmental Dynamics, EarlyView.Abstract Homology in vertebrate body plans is traditionally ascribed to the high‐level conservation of regulatory components within the genetic programs governing them, particularly during the “phylotypic stage.” However, advancements in embryology and molecular phylogeny have unveiled the dynamic nature of gene repertoires responsible for early ...
