A key role for beta-cell cytosolic phospholipase A(2) in the maintenance of insulin stores but not in the initiation of insulin secretion

Cytosolic phospholipase A(2) (cPLA(2)) is a Ca(2+)-sensitive enzyme that has been implicated in insulin secretion in response to agents that elevate beta-cell intracellular Ca(2+) ([Ca(2+)](i)). We generated clones of the MIN6 beta-cell line that stably underexpress cPLA(2) by transfection with a ve...
