By Dale J. Benos (Eds.)

Sodium reabsorbing epithelia play a tremendous position in whole-body sodium homeostasis. a few examples of sodium regulating tissues contain kidney, colon, lung, and sweat ducts. Sodium shipping throughout those membranes is a two-step approach: access via an amiloride-sensitive sodium channel and go out through the ouabain-sensitive sodium/potassium ATPase. The sodium access channels are the rate-limiting determinant for delivery and are regulated through numerous various hormones. The sodium channels additionally play an important function in a couple of illness states, like high blood pressure, edema, drug-induced hyperkalemia, and cystic fibrosis. Amiloride-Sensitive Sodium Channels: body structure and useful variety presents the 1st in-depth trade of principles referring to those sodium channels, their law and involvement in general and pathophysiological events. Key beneficial properties * Summarizes present nation of amiloride-sensitive sodium channel box * Analyzes structure-function of epithelial sodium channels * Discusses immunolocalization of epithelial sodium channels * Examines hormonal rules of sodium channels * Discusses sodium channels in lymphocytes, kidney, and lung * Considers mechanosensitivity of sodium channels * presents principles on sodium channels and sickness

Electrophysiologid Analysis The finding that coexpression of a,p, and yENaC is required for maximal Na+ current suggests that ENaC is a heteromultimeric channel. Genetic evidence from C. elegans suggests that the degenerins also function as heteromultimers (Tavernarakis and Driscoll, 1997). , 1998). , 1997) previously found that a residue within the second transmembrane lines the channel pore. Wild-type hENaC is segment of yhENaC insensitive to the cysteine-reactive compound MTSET (Fig. 4A). However, when Gly536was replaced by cysteine (yG536C), MTSET irreversibly inhibited hENaC (87%, Fig.
