Minireview on Regulation of Intestinal Calcium Absorption
An overview of current information on the mechanisms by which intestinal calcium absorption occurs is described in this article. Both paracellular and transcellular pathways are analyzed. Special emphasis focuses on molecules participating in the latter pathway, such as TRPV5 and TRPV6 channels, located in the apical region of the enterocytes, CB 9k and CB 28k , presumably involved in the catio...
متن کاملEffect of oral citrate on calcium absorption after an oral load of calcium phosphate.
To assess interferences of carboxylester hydrolase (EC 3.1.1.1), which can cleave some pancreatic lipase substrates (4), we added 12 200 U of porcine liver carboxylesterase cat. no. E 3128) per liter to the reaction mixture and found no increase in lipase activity. negative values with the triolein assay, were also determined with the UV kinetic assay. In 28 samples, a value <5 U/L was observed...
متن کاملAluminum citrate prevents renal injury from calcium oxalate crystal deposition.
Calcium oxalate monohydrate crystals are responsible for the kidney injury associated with exposure to ethylene glycol or severe hyperoxaluria. Current treatment strategies target the formation of calcium oxalate but not its interaction with kidney tissue. Because aluminum citrate blocks calcium oxalate binding and toxicity in human kidney cells, it may provide a different therapeutic approach ...
متن کاملIntestinal Calcium Absorption among Hypercalciuric Patients with or without Calcium Kidney Stones.
BACKGROUND AND OBJECTIVES Idiopathic hypercalciuria is a frequent defect in calcium kidney stone formers that is associated with high intestinal calcium absorption and osteopenia. Characteristics distinguishing hypercalciuric stone formers from hypercalciuric patients without kidney stone history (HNSFs) are unknown and were explored in our study. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS...
متن کاملRecent developments in intestinal calcium absorption.
Calcium absorption proceeds by transcellular and paracellular flux, with the latter accounting for most absorbed calcium when calcium intake is adequate. Vitamin D helps regulate transcellular calcium transport by increasing calcium uptake via a luminal calcium channel and by inducing the cytosolic calcium transporting protein, calbindinD(9k). Recent studies utilizing knockout mice have challen...
