whereas previous studies have suggested that d-glucose and/or camp may inhibit atpase activities in islets , these results indicate that the agents , i.e. , d-glucose and camp , which stimulate and/or potentiate insulin secretion from the islet cell , do not modify ca2+ fluxes by directly regulating the islet-cell plasma membrane ( ca2+ + mg2+ ) -atpase .
