Re: The Role of Calbindin-D28k on Renal Calcium and Magnesium Handling during Treatment with Loop and Thiazide Diuretics.

Calbindin-D28k (CBD-28k) is a calcium binding protein located in the distal convoluted tubule (DCT) and plays an important role in active calcium transport in the kidney. Loop and thiazide diuretics affect renal Ca and Mg handling: both cause Mg wasting, but have opposite effects on Ca excretion as loop diuretics increase, but thiazides decrease, Ca excretion. To understand the role of CBD-28k ...

Increased expression of renal TRPM6 compensates for Mg2+ wasting during furosemide treatment

BACKGROUND Furosemide is a loop diuretic, which blocks the Na(+), K(+), 2Cl(-) cotransporter (NKCC2) in the thick ascending limb of Henle (TAL). By diminishing sodium (Na(+)) reabsorption, loop diuretics reduce the lumen-positive transepithelial voltage and consequently diminish paracellular transport of magnesium (Mg(2+)) and calcium (Ca(2+)) in TAL. Indeed, furosemide promotes urinary Mg(2+) ...

Effects of furosemide on renal calcium handling.

Furosemide is a loop diuretic agent that has been used to treat hypercalcemia because it increases renal calcium excretion. The effect of furosemide on calcium transport molecules in distal tubules has yet to be investigated. We conducted studies to examine the effects of furosemide on renal calcium excretion and expression of calcium transport molecules in mice. Mice were administered with a s...

Effect of thiazide on renal gene expression of apical calcium channels and calbindins.

Thiazide diuretics are specific inhibitors of the Na-Cl cotransporter in the distal convoluted tubule (DCT). In addition to producing diuresis and natriuresis, they have a hypocalciuric effect. Recently, two apical calcium channels have been identified, transient receptor potential vanilloid 5 (TRPV5) and TRPV6; both are expressed in the DCT. We studied the effects of thiazides on mouse renal c...

Familial hypomagnesaemia with hypercalciuria and nephrocalcinosis: clinical and molecular characteristics

Familial hypomagnesaemia with hypercalciuria and nephrocalcinosis (FHHNC) is an autosomal-recessive renal tubular disorder characterized by excessive urinary losses of magnesium and calcium, bilateral nephrocalcinosis and progressive chronic renal failure. Presentation with FHHNC symptoms generally occurs early in childhood or before adolescence. At present, the only therapeutic option is suppo...
