Characterization of the Na+-dependent Mg2+ transport in sheep ruminal epithelial cells.
This study examines the routes by which Mg2+ leaves cultured ovine ruminal epithelial cells (REC). Mg2+-loaded (6 mM) REC were incubated in completely Mg2+-free solutions with varying Na+ concentrations, and the Mg2+ extrusion rate was calculated from the increase of the Mg2+ concentration in the incubation medium determined with the aid of the fluorescent probe mag-fura 2 (Na+ salt). In other ...

متن کاملAnion-dependent Mg2+ influx and a role for a vacuolar H+-ATPase in sheep ruminal epithelial cells.
The K+-insensitive component of Mg2+ influx in primary culture of ruminal epithelial cells (REC) was examined by means of fluorescence techniques. The effects of extracellular anions, ruminal fermentation products, and transport inhibitors on the intracellular free Mg2+ concentration ([Mg2+]i), Mg2+ uptake, and intracellular pH were determined. Under control conditions (HEPES-buffered high-NaCl...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.

Schweigel, Monika, Jürgen Vormann, and Holger Martens. Mechanisms of Mg21 transport in cultured ruminal epithelial cells. Am. J. Physiol. Gastrointest. Liver Physiol. 278: G400–G408, 2000.—Net Mg21 absorption from the rumen is mainly mediated by a transcellular pathway, with the greater part (62%) being electrically silent. To investigate this component of Mg21 transport, experiments were perfo...
