Aquaporins (AQPs) are membrane channel proteins which facilitate the rapid transport of water across cellular membrane and are of fundamental importance to the control of cell volume and transcellular water traffic. In the present study using bioinformatic tools an in silico modeling and analysis of aquaporin protein sequences of catfish Heteropneustes fossilis was conducted. Primary structure ...
Semiquantitative immunoblotting was used to investigate the expression levels of the four major renal aquaporins, the Na-K-2Cl cotransporter of the thick ascending limb, the type 3 Na-H exchanger, and the Na-K-ATPase in kidneys from rats with cirrhosis secondary to common bile duct ligation (CBDL). These rats had significant water retention and hyponatremia. In contrast to models of cirrhosis i...
In the renal collecting duct, vasopressin increases osmotic water permeability (P(f)) by triggering trafficking of aquaporin-2 vesicles to the apical plasma membrane. We investigated the role of vasopressin-induced intracellular Ca(2+) mobilization in this process. In isolated inner medullary collecting ducts (IMCDs), vasopressin (0.1 nm) and 8-(4-chlorophenylthio)-cAMP (0.1 mm) elicited marked...
Excessive light causes damage to photoreceptor and pigment epithelial cells, and a local edema in the outer retina. Since Müller glial cells normally mediate the osmohomeostasis in the inner retina (mainly via channel-mediated transport of potassium and water), we determined whether retinal light injury causes an alteration in the retinal localization of glial water (aquaporin-4) and potassium ...
