Aggregating Dictyostelium cells release protons when stimulated with cAMP. To find out whether the protons are generated by acidic vesicles or in the cytosol, we permeabilized the cells and found that this did not alter the cAMP-response. Proton effl

Changes in cytosolic Ca2+ play an important role in a wide array of cell types and the control of its concentration depends upon the interplay of many cellular constituents. Resting cells maintain cytosolic calcium ([Ca2+]i) at a low level in the fac

The second beef quality audit was conducted in Canada in 1998-99 to determine the prevalence of quality defects in slaughtered cattle and to monitor changes since the first audit in 1995. Approximately 0.6% of the number of cattle processed annually

Publisher Summary This chapter focuses on the interaction of magnetic fields with coherent (bio)chemical reactions. There is a worldwide interest in the biological effects of extreme-low-frequency (ELF) electromagnetic fields (1 to 1000 Hz). Surprisi

Transient cytosolic calcium elevations are required for chemotaxis and differentiation of Dictyostelium discoideum since Ca2+ chelating buffers introduced into the cells by scrape loading inhibited motility as well as orientation in a Ca2+ specific m

During stimulation of Dictyostelium discoideum amoebae with the chemoattractant cAMP, extracellular calcium is taken up by the cells. The aim of this study was to determine the cytosolic free calcium concentration ([Ca++]i) during chemotaxis of Dicty

Migration of differentiated cells to a capillary containing cyclic AMP was enhanced in the presence of 1 mM CaCl2 and was virtually absent in the presence of 1 mM EGTA. Furthermore, the cells contracted and extended pseudopods to a capillary filled w

Within about 10 seconds after stimulation of Dictyostelium discoideum cells with cyclic AMP an increased rate of 45Ca influx was observed. Part of the cellular calcium reappeared in the extracellular medium between 1 and 3 minutes after stimulation.

Evidence for cell surface protein kinases as possible regulatory factors of cell interaction in Dictyostelium discoideum was examined by incubating intact cells with γ 32P-ATP in the presence and absence of histone. No significant incorporation of 3

Transient binding of cyclic AMP to aggregating cells of Dictyostelium discoideum was measured under cyclic GMP excess in order to inhibit cyclic AMP hydrolysis by cell-bound phosphodiesterase. Cyclic GMP extended the period of half-maximal cyclic AMP
