Life in the freezer: protein metabolism in Antarctic fish [PDF]
Royal Society Open Science, 2022 Whole-animal, in vivo protein metabolism rates have been reported in temperate and tropical, but not Antarctic fish. Growth in Antarctic species is generally slower than lower latitude species. Protein metabolism data for Antarctic invertebrates show low

A symbiotic bacterium of Antarctic fish reveals environmental adaptability mechanisms and biosynthetic potential towards antibacterial and cytotoxic activities [PDF]
Frontiers in Microbiology, 2023 Antarctic microbes are important agents for evolutionary adaptation and natural resource of bioactive compounds, harboring the particular metabolic pathways to biosynthesize natural products. However, not much is known on symbiotic microbiomes of fish in

Antarctic Fish as a Global Pollution Sensor: Metals Biomonitoring in a Twelve-Year Period [PDF]
Frontiers in Molecular Biosciences, 2021 Antarctica represents a unique natural laboratory for ecotoxicological studies as it is characterized by low internal pollutants emissions but high external contamination levels.

Structural and functional properties of Antarctic fish cytoglobins-1: Cold-reactivity in multi-ligand reactions [PDF]
Computational and Structural Biotechnology Journal, 2020 While the functions of the recently discovered cytoglobin, ubiquitously expressed in vertebrate tissues, remain uncertain, Antarctic fish provide unparalleled models to study novel protein traits that may arise from cold adaptation.

Comparison of Fatty Acid Contents and MMP-1 Inhibitory Effects of the Two Antarctic Fish, Notothenia rossii and Champsocephalus gunnari [PDF]
Molecules, 2022 Total fatty-acid (FA) contents of different organs (stomach, liver, brain, and skin) of two Antarctic fish, marbled rockcod (Notothenia rossii) and mackerel icefish (Champsocephalus gunnari), were examined using gas chromatography–mass spectrometry (GC ...

A structural peculiarity of Antarctic fish IgM drives the generation of an engineered mAb by CRISPR/Cas9 [PDF]
Frontiers in Bioengineering and BiotechnologyIgM is the major circulating Ig isotype in teleost fish, showing in Antarctic fish unique features such as an extraordinary long hinge region, which plays a crucial role in antibody structure and function. In this work, we describe the replacement of the

Are Sponges Good Natural Sentinels for Monitoring Fish Diversity in Antarctic Coastal Waters? [PDF]
Ecology and EvolutionMonitoring biodiversity in Antarctic ecosystems poses significant challenges, particularly due to the harsh environment. Traditional methods, such as beach seines, are time‐consuming, resource‐intensive, and difficult to carry out in Antarctica.

First data on the daily food consumption by Antarctic fish Trematomus hansoni (Actinopterygii: Perciformes: Nototheniidae) in captivity [PDF]
Acta Ichthyologica et Piscatoria, 2020 In this study, we present first observations on the feeding behaviour of an Antarctic notothenioid fish, the striped rockcod, Trematomus hansoni Boulenger, 1902.

Effect of elevated temperature on membrane lipid saturation in Antarctic notothenioid fish [PDF]
PeerJ, 2018 Homeoviscous adaptation (HVA) is a key cellular response by which fish protect their membranes against thermal stress. We investigated evolutionary HVA (long time scale) in Antarctic and non-Antarctic fish.
