Replicated anthropogenic hybridisations reveal parallel patterns of admixture in marine mussels. [PDF]

Evol Appl, 2020
Human‐mediated transport creates secondary contacts between genetically differentiated lineages, bringing new opportunities for gene exchange. When similar introductions occur in different places, they provide informally replicated experiments for ...

Characterization of a New Toti-like Virus in Sea Bass, Dicentrarchus labrax. [PDF]

Viruses, 2023
The European sea bass Dicentrarchus labrax is the main species reared in Mediterranean aquaculture. Its larval stage, which is very sensitive and highly affected by sanitary and environmental conditions, is particularly scrutinized in hatcheries ...

Assessing the Acute and Chronic Effects of Palladium on Daphnia magna and the Influence of Natural Organic Matter. [PDF]

J Appl Toxicol
ABSTRACT In recent decades, rising industrial demand for palladium (Pd), driven by its unique properties and affordability compared to other noble metals, has increased its environmental release into aquatic systems. This highlights the need to assess its effects on organisms, given the lack of standardized toxicity studies and regulations for this ...

Metabolic disrupting chemicals in the intestine: the need for biologically relevant models: Zebrafish: what can we learn from this small environment-sensitive fish? [PDF]

FEBS Open Bio
In this review, we aimed to study how the intestine may be disrupted by metabolic endocrine disruptors (MDCs) both in its own metabolism and in its relationships with other organs. Zebrafish shares numerous similarities with human gastrointestinal tract, representing an opportunity to study the complex interactions of MDCs at the intestinal level and ...

Mutation of Brain Aromatase Impairs Behavior and Neuroplasticity in Adult Zebrafish. [PDF]

J Neurochem
This study investigates the functional role of brain aromatase, encoded by the cyp19a1b gene, in zebrafish neurodevelopment and adult behavior. Using TALENs technology, we introduced a 10‐nucleotide deletion in exon 2, generating a zebrafish line that expresses a truncated aromatase protein.

Biofilm vs. Planktonic Lifestyle: Consequences for Pesticide 2,4-D Metabolism by Cupriavidus necator JMP134. [PDF]

Front Microbiol, 2017
The development of bacterial biofilms in natural environments may alter important functions, such as pollutant bioremediation by modifying both the degraders' physiology and/or interactions within the matrix. The present study focuses on the influence of

Molecular Characterization of Voltage-Gated Sodium Channels and Their Relations with Paralytic Shellfish Toxin Bioaccumulation in the Pacific Oyster Crassostrea gigas. [PDF]

Mar Drugs, 2017
Paralytic shellfish toxins (PST) bind to voltage-gated sodium channels (Nav) and block conduction of action potential in excitable cells. This study aimed to (i) characterize Nav sequences in Crassostrea gigas and (ii) investigate a putative relation ...

Human and zebrafish mineralocorticoid receptors reporter cell assays to assess the activity of chemicals. [PDF]

iScience
Summary: The action of environmental chemicals (ECs) on the mineralocorticoid receptor (MR) has been suggested to impair physiological processes regulated by this nuclear receptor. However, it remains understudied both as a target of ECs and with respect
