Deletion of the KV1.1 Potassium Channel Causes Epilepsy in Mice
Mice lacking the voltage-gated potassium channel alpha subunit, K(V)1.1, display frequent spontaneous seizures throughout adult life. In hippocampal slices from homozygous K(V)1.1 null animals, intrinsic passive properties of CA3 pyramidal cells are normal. However, antidromic action potentials are recruited at lower thresholds in K(V)1.1 null slices. Furthermore, in a subset of slices, mossy f...
متن کاملElevated blood pressure linked to primary hyperaldosteronism and impaired vasodilation in BK channel-deficient mice.
BACKGROUND Abnormally elevated blood pressure is the most prevalent risk factor for cardiovascular disease. The large-conductance, voltage- and Ca2+-dependent K+ (BK) channel has been proposed as an important effector in the control of vascular tone by linking membrane depolarization and local increases in cytosolic Ca2+ to hyperpolarizing K+ outward currents. However, the BK channel may also a...
متن کاملGenetics of primary hyperaldosteronism.
Hypertension is a common medical condition and affects approximately 20% of the population in developed countries. Primary aldosteronism is the most common form of secondary hypertension and affects 8-13% of patients with hypertension. The two most common causes of primary aldosteronism are aldosterone-producing adenoma and bilateral adrenal hyperplasia. Familial hyperaldosteronism types I, II ...
متن کاملRenal calculi in primary hyperaldosteronism.
Increased urinary calcium (Ca++) excretion and the presence of negative Ca++ balance is well documented in primary hyperaldosteronism. However, renal calculi as a major manifestation of this disorder is not previously described. This report describes probably the first patient who presented with renal calculi in association with primary hyperaldosteronism. We believe that primary hyperaldostero...
متن کاملHyperaldosteronism in Klotho-deficient mice.
Klotho is a membrane protein participating in the inhibitory effect of FGF23 on the formation of 1,25-dihydroxyvitamin-D(3) [1,25(OH)(2)D(3)]. It participates in the regulation of renal tubular phosphate reabsorption and stimulates renal tubular Ca(2+) reabsorption. Klotho hypomorphic mice (klotho(hm)) suffer from severe growth deficit, rapid aging, and early death, events largely reversed by a...
