Mouse spermatozoa stimulated with epidermal growth factor (EGF) or zona pellucida (ZP) experienced phosphatidylinositol 4,5-bisphosphate hydrolysis, diacylglycerol (DAG) generation and acrosomal exocytosis. The agonists showed additive effects but the action of EGF is likely to be mediated by a distinct receptor because maximal stimulation achieved with EGF was enhanced further by ZP. Generation of...
We investigated whether GABA activates phospholipase A 2 (PLA 2 ) during acrosomal exocytosis, and if the MEK-ERK1/2 pathway modulates PLA 2 activation initiated by GABA, progesterone or zona pellucida (ZP). In guinea pig spermatozoa prelabelled with [ 14 C]arachidonic acid or [ 14 C]choline chloride, GABA stimulated a decrease in phosphatidylcholine (PC), and...
