“ Carbachol , a muscarinic receptor agonist, stimulated the release of arachidonic acid and inositol phosphates with similar potencies.”
“Long-term preincubation with PMA or carbachol inhibited PKC activity and prevented carbachol-stimulated release of arachidonic acid , but not inositol phosphates, suggesting that release of arachidonic acid, but not release of inositol phosphates, required activation of PKC.”
