The calcineurin homologous protein (CHP) belongs to an evolutionarily conserved Ca(2+)-binding protein subfamily. The CHP subfamily is composed of CHP1, CHP2, and CHP3, which in vertebrates share… (More)
We have demonstrated that Na(+)/H(+) exchanger regulatory factor 1 (NHERF1) overexpression in CFBE41o- cells induces a significant redistribution of F508del cystic fibrosis transmembrane conductance… (More)
Regulation of renal apical Na+/H+ exchanger 3 (NHE3) activity by adenosine has been suggested to contribute to acute control of mammalian Na(+) homeostasis. The mechanism by which adenosine controls… (More)
The Na(+)/H(+)-exchanger 3 (NHE3) is essential for regulation of Na(+) transport in the renal and intestinal epithelium. Although changes in cell surface abundance control NHE3 function, the… (More)
Na+/H+ exchangers (NHEs) extrude protons from, and take up sodium ions into cells. Six isoforms, NHE-1 - NHE-6, have been cloned. NHE proteins are composed of an N-terminal domain, which most likely… (More)
BACKGROUND
Dopamine (DA) is a principal natriuretic hormone that defends extracellular fluid volume from a Na load. Natriuresis is effected partly through inhibiting the proximal tubule Na/H… (More)
The opioid receptor antagonist, naloxone, has been shown to have beneficial effects in the kidney and to be implicated in renal salt and water balance. In the present study the signal transduction… (More)
PURPOSE OF REVIEW
Na/H exchangers (NHEs) are ubiquitous proteins with a very wide array of physiological functions, and they are summarized in this paper in view of the most recent advances.… (More)
Adenosine is an autacoid that regulates renal Na(+) transport. Activation of adenosine A(1) receptor (A(1)R) by N(6)-cyclopentidyladenosine (CPA) inhibits the Na(+)/H(+) exchanger 3 (NHE3) via… (More)
Nephrogenic dopamine is a potent natriuretic paracrine/autocrine hormone that is central for mammalian sodium homeostasis. In the renal proximal tubule, dopamine induces natriuresis partly via… (More)
