TL;DR: The genetic heterogeneity of the human and rat vitamin D-binding protein did not affect its affinity or capacity for both vitamin D metabolites.

TL;DR: The present findings indicate that the frequency of the amphibian bladder to water and enhance of such membrane continuities is greatly increased the transport of sodium across the mucosal in cells stimulated by oxytocin or the dibutyryl epithelium.
Abstract: It is well established that neurohypophyseal observations (40) of çontinuity between the hormones and cyclic 3',5'-adenosine monogranule membrane and the plasma membrane . phosphate (cAMP) increase the permeability The present findings indicate that the frequency of the amphibian bladder to water and enhance of such membrane continuities is greatly increased the transport of sodium across the mucosal in cells stimulated by oxytocin or the dibutyryl epithelium (16, 17, 27) . Recently, we reported derivative of cAMP as compared to unstimulated that in the toad bladder mucosal epithelium, the controls . altered permeability is paralleled by a marked increase in the endocytic uptake of horseradish MATERIALS AND METHODS peroxidase from the lumen (31-33) . One of the The following compounds were used in this study : possible explanations was that the observed oxytocin, prepared by Miss P. L. Hoffman at Mt . endocytosis might be a secondary effect .

TL;DR: These experiments provide the first demonstration that cellular swelling increases [Ca]i, which is likely to play a critical role in cellular volume regulation.
Abstract: We investigated the role of intracellular calcium in epithelial cell volume regulation using cells isolated from the toad urinary bladder. A suspension of cells was prepared by treatment of the bla...
