The emergence of Pax7-expressing muscle stem cells during vertebrate head muscle development [PDF]

open access: yes, 2015
Pax7 expressing muscle stem cells accompany all skeletal muscles in the body and in healthy individuals, efficiently repair muscle after injury. Currently, the in vitro manipulation and culture of these cells is still in its infancy, yet muscle stem ...

NPF2 is involved in intracellular pH regulation and ion balance in the diatom Phaeodactylum tricornutum

open access: yesNew Phytologist, EarlyView.
Summary Cellular ion and pH homeostasis are crucial factors affecting and regulating metabolic reactions, protein stability, signalling and transport mechanisms. To balance intracellular ion concentrations, organisms need to constantly sense and respond to both the extracellular environment and cell compartments' requests.

Association of TCTP with Centrosome and Microtubules

open access: yesBiochemistry Research International, 2012
Translationally Controlled Tumour Protein (TCTP) associates with microtubules (MT), however, the details of this association are unknown. Here we analyze the relationship of TCTP with MTs and centrosomes in Xenopus laevis and mammalian cells using ...

Xenopus laevis as a Model Organism for the Study of Spinal Cord Formation, Development, Function and Regeneration

open access: yesFrontiers in Neural Circuits, 2017
The spinal cord is the first central nervous system structure to develop during vertebrate embryogenesis, underscoring its importance to the organism. Because of its early formation, accessibility to the developing spinal cord in amniotes is challenging,

Modulation by cAMP of a Slowly Activating Potassium Channel Expressed in \u3cem\u3eXenopus\u3c/em\u3e Oocytes [PDF]

open access: yes, 1992
When expressed in the Xenopus oocyte, the minK protein induces a slowly activating voltage-dependent potassium current (Isk). We studied the modulation of this current by altering intracellular cAMP levels and found that the amplitude of Isk is ...

Biocompatible polymer-assisted dispersion of multi walled carbon nanotubes in water, application to the investigation of their ecotoxicity using Xenopus laevis amphibian larvae [PDF]

open access: yes, 2013
Carbon nanotubes (CNTs) tend to readily agglomerate and settle down in water, while the adsorption of compounds present in natural aquatic media could enhance their dispersion and stabilization in the water column.

Spatial Regulation of Silicon Accumulation in Peduncle Confers Sheathed Spike in Barley

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Peduncle, the uppermost internode in cereals, connects the stem to the inflorescence and is critical for the transport of water, nutrients and photosynthetic assimilates. While peduncle length associates with plant height and its elongation is primarily regulated by phytohormones, we report a previously unrecognized mechanism involving the ...

Development of Antimicrobial Peptides from Amphibians

open access: yesAntibiotics, 2020
Since the discovery of magainins from the skin secretions of the African toad Xenopus laevis by Michael Zasloff in 1987, an increasing number of antimicrobial peptides (AMPs) has been identified in different anuran species and studied in detail [...]

MCT1‐mediated bidirectional propionate transport across human placental syncytiotrophoblast layer: insights from a trophoblast stem cell‐derived barrier model

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Propionate in the fetal circulation is thought to originate from fermentation of dietary fibre by the maternal gut microbiota. However, the mechanism of transplacental transport has remained unclear. Here, we measured propionate permeability using a placental barrier model generated by differentiating human placental trophoblast ...

Early Head Specification in Xenopus laevis

open access: yesThe Scientific World Journal, 2003
The head represents the most dorsal and anterior extent of the body axis. In Xenopus, the progressive determination of the head is an extremely complex process involving the activation and localized antagonism of a number of interdependent intracellular ...
