Caveolin 1 Promotes Renal Water and Salt Reabsorption.


ABSTRACT: Caveolin-1 (Cav1) is essential for the formation of caveolae. Little is known about their functional role in the kidney. We tested the hypothesis that caveolae modulate renal salt and water reabsorption. Wild-type (WT) and Cav1-deficient (Cav1-/-) mice were studied. Cav1 expression and caveolae formation were present in vascular cells, late distal convoluted tubule and principal connecting tubule and collecting duct cells of WT but not Cav1-/- kidneys. Urinary sodium excretion was increased by 94% and urine flow by 126% in Cav1-/- mice (p?
