Liddle syndrome (pseudohyperaldosteronism), a severe form of salt-sensitive hypertension, is caused by gain-of-function mutations of ENaC, but the precise tubular site of increased ENaC function is unknown. In the cortical collecting duct (CCD), ENaC is known to be regulated by aldosterone. In contrast, we recently reported aldosterone-independent ENaC regulation in the early part of the aldosterone-sensitive distal nephron. Here, we investigated ENaC function in the transition zone of DCT2/CNT or CNT/CCD microdissected from mice homozygous for Liddle syndrome mutation or from wild-type control mice. Whole-cell patch-clamp recordings were used to measure amiloride-sensitive ENaC currents in nephron fragments from mice maintained on different sodium diets to vary plasma aldosterone levels. Our data indicate that in mice with Liddle syndrome, the primary site of increased Na(+) reabsorption is the DCT2/CNT. In addition, increased aldosterone responsiveness of ENaC in CNT/CCD may contribute to salt-sensitive hypertension in Liddle syndrome. Single channel properties of ENaC were similar in Liddle syndrome mutation and wild-type mice, but ENaC expression at the apical membrane was increased in Liddle syndrome mutation when compared with wild-type mice, in particular, in animals maintained on a high salt diet. Our findings highlight the importance of ENaC function and regulation in the early part of the aldosterone-sensitive distal nephron for the maintenance of sodium balance and blood pressure control."}],"user_id":"49428","department":[{"_id":"35"},{"_id":"22"}],"type":"journal_article","language":[{"iso":"eng"}],"publisher":"Ovid Technologies (Wolters Kluwer Health)","author":[{"full_name":"Nesterov, Viatcheslav","last_name":"Nesterov","first_name":"Viatcheslav"},{"first_name":"Bettina","orcid":"0000-0001-5351-1785","id":"49428","full_name":"Krueger, Bettina","last_name":"Krueger"},{"full_name":"Bertog, Marko","last_name":"Bertog","first_name":"Marko"},{"first_name":"Anke","last_name":"Dahlmann","full_name":"Dahlmann, Anke"},{"first_name":"Ralf","full_name":"Palmisano, Ralf","last_name":"Palmisano"},{"last_name":"Korbmacher","full_name":"Korbmacher, Christoph","first_name":"Christoph"}],"issue":"6","volume":67,"title":"In Liddle Syndrome, Epithelial Sodium Channel Is Hyperactive Mainly in the Early Part of the Aldosterone-Sensitive Distal Nephron","year":"2016"}
