Characterisation and expression analysis of cathepsins and ubiquitin-proteasome genes in gilthead sea bream (Sparus aurata) skeletal muscle [PDF]

, 2015
The proteolytic enzymes involved in normal protein turnover in fish muscle are also responsible for post-mortem softening of the flesh and are therefore potential determinants of product quality. The main enzyme systems involved are calpains, cathepsins,

The Chemistry and Biology of the Tetrodotoxin Natural Product Family

Angewandte Chemie International Edition, Volume 64, Issue 35, August 25, 2025.
Tetrodotoxin is best known as the poison of the pufferfish, which is a delicacy in Japanese cuisine. Its toxicity arises from the selective blockage of NaV channels, which is depicted for the NaV1.7 pore, highlighting the DEKA motif, which permeates sodium ions.

Biased amino acid composition in warm-blooded animals [PDF]

, 2009
Among eubacteria and archeabacteria, amino acid composition is correlated with habitat temperatures. In particular, species living at high temperatures have proteins enriched in the amino acids E-R-K and depleted in D-N-Q-T-S-H-A. Here, we show that this

Evolution of gene function and regulatory control after whole-genome duplication: Comparative analyses in vertebrates [PDF]

, 2009
The significance of whole-genome duplications (WGD) for vertebrate evolution remains controversial, in part because the mechanisms by which WGD contributed to functional evolution or speciation are still incompletely characterized.

Genomic Signals of Local Adaptation Associated With Environmental Variables in Eleginops maclovinus From Northern Chilean Patagonia

Ecology and Evolution, Volume 15, Issue 6, June 2025.
Studying evolutionary processes in the unique and understudied Patagonian fjord ecosystem is a challenging task for evolutionary ecologists. Genomic signals of local adaptation are present in a species from northern Chilean Patagonia. Polygenic selection drives local adaptation in Eleginops maclovinus. ABSTRACT Understanding the evolutionary mechanisms

Megalocytivirus: A Review of Epidemiology, Pathogenicity, Immune Evasion, and Prevention Strategies

Reviews in Aquaculture, Volume 17, Issue 3, June 2025.
ABSTRACT Megalocytivirus, a large double‐stranded DNA virus belonging to the Iridoviridae family, has infected over 100 species of fish, leading to significant economic losses in the aquaculture, food, and ornamental fish industries. These viruses exhibit icosahedral symmetry and have diameters ranging from 120 to 200 nm.

Genetic Diversity of Chinese Giant Salamanders Under the Context of Translocation Using Novel Development of Genomic SSR Markers

Ecology and Evolution, Volume 15, Issue 5, May 2025.
This study developed 19 novel genomic SSR markers for the critically endangered Chinese giant salamander (Andrias spp.) using next‐generation sequencing, revealing 316,313 SSR loci. Analysis of 60 wild individuals across six sites in Hunan Zhangjiajie Giant Salamander National Nature Reserve identified the highest genetic diversity in the long‐term ...

Comparative analysis of vertebrate () genes and assignment of the equine gene to ECA15q24–q25 and the bovine gene to BTA11q12–q15 [PDF]

, 2006
The structures of the canine, rabbit, bovine and equine EIF2AK2 genes were determined. Each of these genes has a 5' non-coding exon as well as 15 coding exons.

Transcriptomic Divergence and Associated Markers Between Genomic Lineages of Silver Catfish (Rhamdia quelen)

Ecology and Evolution, Volume 15, Issue 3, March 2025.
We present transcriptomic divergence between two latitudinally distributed lineages of Rhamdia quelen, which could explain local adaptations and the speciation processes proposed in previous studies. Moreover, the differentiation of transposable elements between lineages could also be associated with this speciation process.

Molecular characterization of apolipoprotein A-I from the skin mucosa of Cyprinus carpio [PDF]

, 2017
Apolipoprotein A-I is the most abundant protein in Cyprinus carpio plasma that plays an important role in lipid transport and protection of the skin by means of its antimicrobial activity.
