ionoregulation
- Zonation of Ca2+ transport and enzyme activity in the caeca of rainbow trout – a simple structure with complex functions
Summary: A novel technique revealed region-specific ion transport properties within the caeca of rainbow trout. Feeding and environmental manipulation altered ion transport characteristics, which changes in enzyme activity supported.
- Functional plasticity of the gut and the Malpighian tubules underlies cold acclimation and mitigates cold-induced hyperkalemia in Drosophila melanogaster
Summary: Previous exposure of insects to low temperatures can mitigate cold-induced ion imbalances and improve chill tolerance. Plasticity of ion and fluid transport across the Malpighian tubule and rectal epithelia probably drive this response.
- Effects of rearing salinity on expression and function of ion-motive ATPases and ion transport across the gastric caecum of Aedes aegypti larvae
Summary: Vacuolar H+-ATPase-rich and Na+/K+-ATPase-rich cells along the gastric caecum may play an important role in osmoregulation and uptake of nutrients.
- The role of acid-sensing ion channels in epithelial Na+ uptake in adult zebrafish (Danio rerio)
Summary: Acid-sensing ion channels in zebrafish gill epithelium are involved in Na+ uptake.
