Starvation stimulates pancreatic PGE content.
Recent evidence suggests that prostaglandins may exert a tonic inhibitory tone in the pancreatic beta cell during starvation. The effects of starvation on rat pancreatic prostaglandin E (PGE) content were studied. After 72 hrs of starvation, pancreatic PGE increased 250% above that of fed controls. Administration of streptozotocin, a selective beta-cell toxin, decreased pancreatic PGE significantly (p less than 0.005), but starvation partially reversed this trend. Thus, PGE may have a physiological role in modulating insulin secretion during starvation. It appears that both beta-cell and nonbeta-cell sources of PGE are involved in this phenomenon.
