In vitro cellular muscle calcium metabolism. Characterization of effects of 1,25-dihydroxy-vitamin D3 and 25-hydroxy-vitamin D3.
Cultures of vitamin D-deficient chick soleus muscle and 12 day-old chick embryo myoblasts were used to characterize the effects of 1,25-dihydroxy-vitamin D3 and 25-hydroxy-vitamin D3 on muscle cell Ca metabolism. Physiological amounts of both sterols increased the rate and extent of 45Ca uptake by cultures. However, 1,25(OH)2D3 was significantly more effective than 25 OHD3. The greater potency ...
متن کاملEffect of 1,25-dihydroxy-vitamin D3 in experimental sepsis
BACKGROUND In addition to the regulation of calcium homeostasis, vitamin D affects the cellular immune system, targets the TNF-alpha pathway and increases vasoconstrictor response to angiotensin II. We therefore examined the effect of 1,25-dihydroxy-vitamin D(3) on coagulation and organ failure in experimental sepsis in the rat. METHODS Three series of placebo-controlled studies were conducte...
متن کاملIsolation and chemical characterization of two new vitamin D metabolites produced by the intestine. 1,25-Dihydroxy-23-oxo-vitamin D3 and 1,25,26-trihydroxy-23-oxo-vitamin D3.
Two new vitamin D metabolites were isolated in pure form from incubations of 53 nM 1,25-dihydroxyvitamin D3 with homogenates of small intestinal mucosa of vitamin D-replete chicks. The birds were injected intravenously with 8 to 9 nmol of 1,25-dihydroxyvitamin D3/100 g body weight 5 to 8 h before death. The isolation involved methanol-chloroform extraction and four successive chromatographic pr...
متن کاملAssay of 1,25-dihydroxy vitamin D3 by isotope dilution--mass fragmentography.
We describe a specific assay of 1,25-dihydroxy vitamin D3 in human serum, based on isotope dilution-mass fragmentography. We added [26-2H3]-1,25-dihydroxy vitamin D3 to a fixed amount of serum. The steroids were extracted with chloroform/methanol and purified by liquid chromatography. The purified materal was converted into the trimethylsilyl ether and analyzed. Unlabeled 1,25-dihydroxy vitamin...
متن کاملStimulation of calmodulin binding to skeletal muscle membrane proteins by 1,25-dihydroxy-vitamin D3.
Previous work has shown that 1,25-dihydroxy-vitamin D3 rapidly increases calmodulin levels of skeletal muscle membranes without altering the muscle cell calmodulin content. Therefore, the effects of the sterol on the binding of calmodulin to specific muscle membrane proteins were investigated. Soleus muscles from vitamin D-deficient chicks were treated in vitro for short intervals (5-15 min) wi...
