.... The direct effects on β-adrenenoceptor number, G-protein levels and stimulation of the adenylate cyclase (AC) complex were assessed. In terms of AC activation, ischemia led to a marked increase (4-fold) in sensitivity to terbutaline (β 2 -agonist) and phorbol ester (tetradecanoyl phorbal acetate = TPA...

...) in GTP-binding protein (G-protein)-mediated signal transduction mechanisms in retina, we quantitated NDP kinase activity in subcellular fraction-derived from normal rat retina. A greater than 85% of the total specific activity was present in the soluble fraction, which was stimulated (up to 7 fold) by 2...

.... However, 1,25(OH) 2 D 3 exposure significantly reduced PTH- and Gpp(NH)p-elicited AC as well as Gpp(NH)p-stimulated PLC activities in the UMR 106 cells. These changes were accompanied by an increase and decrease in the membrane contents of the G-protein subunits G 36 β and G q/11 α, respectively...

... and production of diacylglycerol (DAG), while EGF itself neither stimulated DAG nor augmented the DAG response to GTPγS. These findings suggest the intermediacy of a G-protein in PLC-independent stimulation of PLA 2 by a growth factor, and provide a model system for determining the relationship between G-protein...

... phosphodiesterase (PPI-pde) through the mediation of a G-protein (Gp), all the early events can be ascribed to the plasma membrane. Investigation of the exocytotic stage of secretion has been simplified by the use of permeabilised cells in which the composition of the cytosol can be precisely controlled. We have...
