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 investigated the effects of dietary cholesterol on various aspects of Pacific white shrimp. The results showed that a moderate level of cholesterol can improve the growth performance, antioxidant defense, immune response, osmoregulation, and salinity stress resistance of the shrimp.

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: Life in freshwater poses osmotic and energetic challenges for organisms, particularly arthropods. The mechanisms of ion uptake from freshwater environments are still poorly understood, but the proton pump V-type H+ ATPase (VHA) and the Na+/H+ antiporter (NHA) have been proposed as potential models. This study explores the evidence for these models in crustaceans, insects, and teleost fish and emphasizes the need for further research on ion uptake mechanisms in freshwater habitats.

Summary: This study demonstrates how changes in skin mucus production and composition can be used as an indicator of physiological responses and energy expenditure in fish living in different environmental salinities, with European sea bass showing increased energy demand in hyperosmotic conditions.

Summary: The study found that marine medaka's growth and tissue responses in different salinity environments are affected by salinity changes. The gills are more sensitive to extreme hypotonic environments, while the liver is more susceptible to hypertonic environments. Functional analysis of differentially expressed genes showed that gills mainly regulate ion balance and signal transduction, while the liver is involved in protein synthesis and processing.

Summary: Prolonged drought and freshwater diversion are leading to more common periods of hypersalinity in coastal ecosystems, affecting the tolerance of endemic species such as the red drum. This study found significant impacts on plasma osmolality and muscle water in red drum exposed to hypersalinity, but adaptation led to changes in gill and intestinal plasticity to cope with the challenging conditions.

Summary: This study investigated changes in the expression levels of OSTF1, cortisol levels, and their correlation in the marine inhabitant milkfish. The results showed that ostf1b was the primary gene responding to hypertonic stress, and cortisol concentration increased after transferring milkfish from freshwater to seawater. Additionally, cortisol injection increased the expression of ostf1a and ostf1b.

Summary: The study showed that NHE activity was higher in warm-acclimated fish compared to cold-acclimated fish when measured at acclimation temperatures, and the temperature dependence of NHE activity was similar in both groups. The mechanisms regulating Na+/K+ ATPase and NHE activities are complex and essential for maintaining sodium homeostasis.

Summary: In this study, a comparative transcriptome analysis was performed on economically cultured Penaeus monodon in different salinity environments. The results suggest that low salinity stress may affect regulatory mechanisms such as metabolism, immunity, and signal transduction in P. monodon. The greater the difference in salinity, the more significant the difference in genes. This study provides some guidance for understanding the low-salt domestication culture of P. monodon.

Summary: The study found that the specific ion effects of Na+ and K+ were different on the growth of Ulva lactuca. Ulva lactuca showed better growth with high concentrations of NaCl, while KCl might have adverse effects on photosynthesis and cell wall. Transcription of PM H+-ATPase was induced specifically by high concentrations of Na+, while the induction of PM-Na+/K+-ATPase-like alone could not improve the growth of KCl-treated Ulva lactuca.

Summary: This study investigated the osmolality and osmoregulatory mechanisms of Solenaia oleivora under high salinity stress. The results showed that S. oleivora is an osmoconformer, and changes in inorganic ions, FAA, NKA, and gill structure play an important role in its osmoregulation.

Summary: This study analyzed the function of Na+/K+-ATPase in the response of Neoporphyra haitanensis to salt stress and found that it played a crucial role in maintaining the K+/Na+ homeostasis in the algae. The inhibitor ouabain caused Na+ accumulation and K+ leakage in the cells, disrupting the K+/Na+ balance and leading to decreased photosynthesis and oxidative damage in the algae.

Summary: In this study, the crystal structure and functional properties of the E2-BeFx complex of pig kidney Na+,K+-ATPase are investigated. The complex resembles the E2P intermediate and is able to bind ADP/ATP and Na+. The results suggest a relation between E2-BeFx and the E*P intermediate in the functional cycle of Na+, K+-ATPase.
