title: Phenotypes of aquaporin mutants in genetically altered mice.
abstract: The ability to move water across lipid membranes is crucial for nutrient intake, energy generation, waste excretion, and a myriad of other functions associated with life. Aquaporins, a family of integral membrane proteins, are now recognized as the channels responsible for transporting hydrophilic molecules, including water, across relatively impervious, hydrophobic cell membranes. A tremendous amount of work has been published on characterizing these proteins, which have been found in all bacteria, yeast, plants, and animals examined to date. In addition, an increasing number of mouse models with genetically altered aquaporin expression are being reported. This article will briefly review the basic biochemistry of aquaporins and then evaluate the use (and misuse) of mice in the quest for understanding the comparative pathophysiology of aquaporins in humans.
