Environmental changes in oxygen tension reveal ROS-dependent neurogenesis and regeneration in the adult newt brain

open access: yeseLife, 2015
Organisms need to adapt to the ecological constraints in their habitat. How specific processes reflect such adaptations are difficult to model experimentally. We tested whether environmental shifts in oxygen tension lead to events in the adult newt brain

Post-fire species composition and abundance of a lentic-breeding amphibian assemblage: case study of Ledson Marsh

open access: yesCalifornia Fish and Wildlife Journal, 2020
Amphibians frequently inhabit wildfire-prone environments, but little is known how amphibians respond to fire. This study assessed the post-wildfire species composition and abundance of an amphibian assemblage in an 11.8-ha seasonal marsh. Pre-fire, four

Developmental alterations in centrosome integrity contribute to the post-mitotic state of mammalian cardiomyocytes

open access: yeseLife, 2015
Mammalian cardiomyocytes become post-mitotic shortly after birth. Understanding how this occurs is highly relevant to cardiac regenerative therapy. Yet, how cardiomyocytes achieve and maintain a post-mitotic state is unknown.

Comparative transcriptomic analysis and structure prediction of novel Newt proteins.

open access: yesPLoS ONE, 2019
Notophthalmus viridescens (Red-spotted Newt) possess amazing capabilities to regenerate their organs and other tissues. Previously, using a de novo assembly of the newt transcriptome combined with proteomic validation, our group identified a novel family

Superparamagnetic nanoadsorbents for the removal of trace As(III) in drinking water

open access: yesEnvironmental Advances, 2021
A series of novel zeolitic imidazolate framework (ZIF) decorated superparamagnetic graphene oxide hybrid nanoadsorbents were synthesized, characterized, and tested for their As(III) adsorbed amount in simulated drinking water.

Sex pheromones in amphibians: a review

open access: yesVeterinární Medicína, 2005
Amphibians are interesting animals, very often kept by aquarists and vivarists. Their ability of intraspecific chemical signalization belongs to very interesting biological features.

Newt cells secrete extracellular vesicles with therapeutic bioactivity in mammalian cardiomyocytes

open access: yesJournal of Extracellular Vesicles, 2018
Newts can regenerate amputated limbs and cardiac tissue, unlike mammals which lack broad regenerative capacity. Several signaling pathways involved in cell proliferation, differentiation and survival during newt tissue regeneration have been elucidated ...
