Epithelial Mg2+ channel TRPM6: insight into the molecular regulation.
Our understanding of the molecular mechanisms of renal magnesium (Mg2+) handling has greatly enhanced over recent years. This review highlights the regulatory factors controlling Mg2+ homeostasis through its effects on the epithelial Mg2+ channel TRPM6 (Transient Receptor Potential Melastatin subtype 6), the gatekeeper of the body's Mg2+ balance. Drug treatment, acid-base status, and several ho...
متن کاملMg2+ homeostasis: the balancing act of TRPM6.
PURPOSE OF REVIEW The tight control of blood magnesium (Mg) levels is of central importance for numerous physiological processes. A persistent low Mg status (hypomagnesemia) is associated with severe health risks and is involved in the pathogenesis of type 2 diabetes mellitus, osteoporosis, asthma, and heart and vascular diseases. The current view has expanded significantly as a result of the i...
متن کاملMrs2p Forms a High Conductance Mg2+ Selective Channel in Mitochondria
Members of the CorA-Mrs2-Alr1 superfamily of Mg(2+) transporters are ubiquitous among pro- and eukaryotes. The crystal structure of a bacterial CorA protein has recently been solved, but the mode of ion transport of this protein family remained obscure. Using single channel patch clamping we unequivocally show here that the mitochondrial Mrs2 protein forms a Mg(2+)-selective channel of high con...
متن کاملIncreased 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+) ...
متن کاملDietary inulin in mice stimulates Mg2+ absorption and modulates TRPM6 and TRPM7 expression in large intestine and kidney.
Complex fermentable carbohydrates, such as inulin-type fructans have been shown to improve Mg2+ absorption in the hindgut and body stores. The mechanisms for this are not well understood. The newly identified transient receptor potential melastatin 6 and 7 (TRPM6 and TRPM7) channels have been shown to function in active epithelial Mg2+ transport in the apical membrane of epithelial cells, the k...
