Orphanet: ORPHA275777


Role:  Doxicyclin-induced suppression of KCa2.3 expression in transgenic mice overexpressing KCa2.3 leads to an elevation in blood pressure. In mice KCa2.3 overexpression in the absence of KCa3.1 reduces blood pressure compared with double knockout of these two genes.
Therapeutic use:  KCa2.3 activators have been proposed for the treatment of hypertension.
Comments:  KCa2.3 mutation (V450L) associated with autosomal dominant idiopathic non-cirrhotic portal hypertension.
