Magnesium is important for enzymatic reactions and physiological functions, and its intracellular concentration is tightly regulated. Atlantic salmon has the ability to handle large changes in environmental Mg concentration when migrating between freshwater and seawater habitats, making it a relevant model to investigate Mg homeostasis. Parr-smolt transformation (PST) is a life history transition which prepares the freshwater juvenile for the marine environment.

Recently, against the background of increasing land salinization and global warming, many studies have examined the mechanisms of freshwater fish adaptation to elevated salinity. However, the mechanisms underlying salinity tolerance in the kidney of Micropterus salmoides, a popular saline aquaculture species, remain poorly understood. We used RNA-seq to explore the differentially expressed genes (DEGs) in the kidney of M.

Background: Enuresis refers to urinary incontinence during sleep in children over 5 years of age. The pathogenesis of enuresis is complex. It is related to low functional bladder capacity, nocturnal bladder overactivity, and high arousal threshold, and it is also related to the immaturity of the central nervous system.

One of the hallmarks of Shiga toxin-producing Escherichia coli-associated hemolytic uremic syndrome (STEC-HUS) is kidney damage. Our previous research demonstrated that Shiga toxin type 2 (Stx2a) decreases cell viability and induces swelling of human glomerular endothelial cells (HGEC). However, Stx2a can disrupt net water transport across HGEC monolayers without affecting cell viability.

Marine teleosts experience ion gain and water loss in their natural habitats. Among other tissues, the urinary bladder epithelium of marine fishes has been shown to actively transport ions to facilitate water absorption. However, transport properties of the urinary bladder epithelium of marine fishes and its plasticity in altered ambient salinities is relatively under-investigated.
