Chronic palmitate exposure inhibits insulin secretion by dissociation of Ca(2+) channels from secretory granules.
Long-term (72 hr) exposure of pancreatic islets to palmitate inhibited glucose-induced insulin secretion by >50% with first- and second-phase secretion being equally suppressed. This inhibition correlated with the selective impairment of exocytosis evoked by brief (action potential-like) depo...
