Summary: The widespread use of silver in nanomaterials leads to increased environmental contamination, posing a threat to aquatic animals. This study examines how silver affects the osmoregulatory abilities of euryhaline fish, using medaka embryos as a model. The results show that silver has higher toxicity in freshwater, impairing ionocytes and elevating heart rates.

Summary: In this study, the osmoregulatory response of large yellow croaker to low water salinity was investigated. The survival rate of large yellow croaker was stable within a specific salinity range, and the NKA activity in the kidney and gill was regulated by salinity variations. Furthermore, the expression of PRLR, NHE beta, and NCC genes were also associated with salinity changes.

Summary: This study revealed that the abundance of flotillin-2 in branchial LR of tilapia changed with environmental salinities. Flotillin-2 and NKA were exclusively located in LR in both tilapia and milkfish gills, while VHA A was predominantly present in non-LR. The differential distribution and salinity-dependent expression of NKA and VHA A in gill tissues of euryhaline teleosts with different salinity preferences were illustrated in this study.

Summary: Inspired by euryhaline fish, researchers have constructed sandwich-structured nanochannel systems that can adapt to changing salinities. These systems have been used to develop high-performance salinity-gradient power generators. The adaptive membrane solves the surface charge-shielding problem caused by high salinity and improves the overlapping degree of the electric double layer.

Summary: Acute low-salinity stress leads to stress responses in black seabream, but with time, the fish show signs of adaptation to the environmental change. Low salinity stress increases the synthesis of long-chain polyunsaturated fatty acids in the gills, enhancing the fish's osmoregulation ability.

Summary: Alternative splicing (AS) is a key post-transcriptional regulatory mechanism that plays important roles in organisms' response to environmental stimuli. This study utilized 18 RNA-Seq datasets to investigate the potential roles of AS in salinity adaptation in three euryhaline teleosts. The results showed that different salinity environments altered the splicing patterns of RNA splicing regulators, potentially affecting downstream target genes. The study provides new insights into the molecular mechanisms of salinity adaptation in teleosts.

Summary: Ecologists have observed declines in the biodiversity of sensitive freshwater organisms in response to increasing salinization, but the physiological challenges faced by aquatic organisms, such as mayflies, are not well studied. This study used proteomics to identify specific proteins associated with ion transport in mayfly gills and investigate how their abundance changes in response to chronic salinity exposure. The research found differential protein expression in gills under different salinity conditions, and also explored non-transport related pathways in the gills. The study highlights the importance of understanding the impacts of salinization on non-model species.

Summary: Salinization of freshwater affects freshwater insects' osmoregulatory physiology, causing stress and impaired development even though they can tolerate it to a certain extent. Further research is needed to understand the physiological mechanisms for controlling salt and water balance in freshwater insects in order to predict the consequences of salinization for freshwater ecosystems.

Summary: This study investigates the adaptive evolutionary characteristics in euryhaline bivalves through comparative genomics analyses. The results reveal positive selection in genes related to solute transport, antioxidant response, energy metabolism, and membrane lipids adjustments. These findings enhance our understanding of the molecular mechanisms underlying the remarkable salinity adaption of euryhaline bivalves.

Summary: This study assessed the effects of salinity and dietary cholesterol levels on the physiological regulation, cholesterol metabolism, fatty acid composition, and stress responses of black seabream. The results showed that feeding black seabream with 1.0% cholesterol diet in low salinity improved osmoregulation, increased cholesterol synthesis, and reduced degradation. It also promoted the biosynthesis of long-chain polyunsaturated fatty acids and attenuated oxidative stress and endoplasmic reticulum stress.

Summary: Adaptation to a hypertonic marine environment is crucial for animal survival, with marine teleosts being able to compensate for water loss by absorbing water from the surrounding seawater. Eels, known for their euryhalinity, are commonly used in laboratories for osmoregulation research, providing insights into molecular mechanisms of ion and water transport in the digestive tract. Recent advancements in genome databases have enabled a better understanding of these mechanisms at the molecular level.

Summary: Cultivation of Larimichthys crocea in low salinity water is considered effective in treating diseases caused by seawater pathogens. The renal metabolomic analysis on L. crocea showed changes in metabolites related to osmoregulation and energy allocation. These findings provide insights into the adaptation mechanisms of L. crocea to low salinity water and potential guidelines for cultivation.

Summary: The study investigates the regulation and potential role of sulfate transporters in Atlantic salmon during the transition from sulfate uptake to secretion. The findings suggest a kidney-specific increase in slc26a6a1 and slc26a1a, which play a vital role in sulfate excretion and maintaining normal plasma sulfate levels in seawater.
