Abstract:
:The putative ionophoretic action of phosphatidic acid or arachidonic acid metabolites for Ca2+ has offered an attractive explanation for stimulation-coupled mobilization of cytoplasmic Ca2+. We have examined the effects of Ca2+ ionophore and long-chain unsaturated fatty acids on the translocation of Ca2+ across the liposomal membrane by using Quin II-entrapped liposomes, a sensitive assay system for ionophoresis of Ca2+. A23187 increased Quin II fluorescence intensity corresponding to the translocation of Ca2+ into liposomes. Similar translocation was observed with unsaturated long-chain fatty acids but not with saturated fatty acids. Thus, when phospholipases of cell membrane are activated by certain stimuli, unsaturated long-chain fatty acids are liberated and might mediate the mobilization of cytoplasmic Ca2+.
