Aquaporin 3 Water Channel Protein Gene Expression in Squalis Acanthias Dogfish Shark
… that provide channels for the rapid movement of water molecules and some small solutes across the cellular membrane. Since the discovery of the first water channel protein, hundreds of homologous proteins have been found in all forms of life and much has been learned about their complex role in …

Genetic factors associated with performance and exercise-associated weight loss in Ironman triathletes
… in the neuro-endocrine control of total body water homeostasis were also investigated in this thesis.

Molecular Mechanisms of Gating, Selectivity, and Transport in Membrane Channels and Carriers
… their transport across biological membranes. The water channel aquaporin (AQP) and the nucleotide transporter ADP/ATP carrier (AAC) are the focus of the research presented in this thesis. By facilitating water conduction across cellular membranes, AQPs play a significant role in water homeostasis …

Role of the renal nerves in hypertension
… necessary to maintain cardiovascular or sodium/water homeostasis in normotensive rats subjected to dietary sodium loading. We also showed that renal-CAP treatment and complete RDNX caused the same attenuation of deoxycorticosterone-salt HTN, suggesting that the antihypertensive effect of RDNX in …

Modulation of the aquaporin-2 localization in renal principal cells
… protein kinase (protein kinase A, PKA), the water channel aquaporin-2 (AQP2) is redistributed from intracellular vesicles into the plasma membrane of renal collecting duct principal cells. Its insertion into the plasma membrane induces the water reabsorption from primary urine and fine-tunes …

Characterisation of Guanylin and Uroguanylin in the Digestive System
… mucosa with established roles in salt and water homeostasis and the regulation of gut physiology. These hormones are secreted as the propeptides, ProGuanylin and ProUroguanylin, and post- translationally processed into active peptides in the intestinal lumen. Those active peptides activate …

Regulation of sodium channel densities in A6 renal epithelial cells by hormonally-dependent mechanisms
… in the kidney, which is essential for salt and water homeostasis, is therefore governed by the cellular control of ENaC activity. It is well established that the neurohypophysial hormone vasopressin (antidiuretic hormone) is responsible for both water and sodium regulation and, in renal cells, …

Molecular analysis of the responses of Caenorhabditis elegans (Bristol N2), Panagrolaimus rigidus (AF36) and Panagrolaimus sp. (PS 1579) (Nematoda) to water stress
… and genetic analysis of the responses to water stress in desiccation-tolerant and desiccation-sensitive nematodes. Caenorhabditis elegans, a model organism for the study of development, aging, and cell biology was shown to be a desiccation-sensitive organism that survives relative …

Mechanism and energetics of membrane transporters and channels
… of substrate-bound systems also captured a water-conducting ""channel-like"" state. These states were also observed in several other transporters, sug- gesting that alternating-access mechanism tolerates transient states that are partially open to both sides of the membrane. We, later, …

MORPHOLOGICAL FEATURES OF THE REPRODUCTIVE ORGANS IN DOMESTIC SPECIES IN RELATION TO WATER MOVEMENT CONTROL, HYPONUTRITION AND ENVIRONMENTAL INFLUENCES IN FETAL AND PREPUBERTAL LIFE, AND METABOLISM REGULATOR FACTORS.
… 2 hemi-pores, which fold together to form a water channel. Different aqps have different patterns of glycosylation. In the case of AQP1 the peptide backbone is roughly 28 kDa and the glycosylated forms range from 40 to 60 kDa in mass. Water transport activity of AQP1 is inhibited by mercurial …
