Calcium-regulated renal calcium handling in healthy men: relationship to sodium handling.
Several studies have shown an increase in urinary calcium excretion in response to a calcium load. However, because of the inverse changes in PTH levels with a calcium load, the effect of changes in serum calcium per se on its own excretion is unclear in humans. In this study we used a PTH clamp protocol to further characterize calcium-regulated renal calcium and magnesium handling and the rela...

15 صفحه اولRedox regulation of calcium ion channels: chemical and physiological aspects.
Reactive oxygen species (ROS) are increasingly recognized as second messengers in many cellular processes. While high concentrations of oxidants damage proteins, lipids and DNA, ultimately resulting in cell death, selective and reversible oxidation of key residues in proteins is a physiological mechanism that can transiently alter their activity and function. Defects in ROS producing enzymes ca...
متن کاملRedox regulation of cardiac calcium channels and transporters.
Intracellular concentrations of redox-active molecules can significantly increase in the heart as a result of activation of specific signal transduction pathways or the development of certain pathophysiological conditions. Changes in the intracellular redox environment can affect many cellular processes, including the gating properties of ion channels and the activity of ion transporters. Becau...
متن کاملCalcium regulation of sodium hypersensitivities of sos3 and athkt1 mutants.
T-DNA disruption mutations in the AtHKT1 gene have previously been shown to suppress the salt sensitivity of the sos3 mutant. However, both sos3 and athkt1 single mutants show sodium (Na+) hypersensitivity. In the present study we further analyzed the underlying mechanisms for these non-additive and counteracting Na+ sensitivities by characterizing athkt1-1 sos3 and athkt1-2 sos3 double mutant ...
