endocrine/exocrine glands
• in the presence of 16.6 mmol/l glucose, DHA (an n-3 fatty acid, 50 or 100 umol/l) fails to increase insulin secretion from mutant islets in a dose-dependent manner, unlike in similarly treated wild-type islets
• although mice respond normally to glucose with a 2- to 3-fold increase in somatostatin secretion when the glucose concentration is raised from 3 to 16.6 mmol/l, the GPR120 agonist Metabolex 36 (10 or 30 umol/l) fails to inhibit glucose-induced somatostatin secretion from mutant islets in the presence of 16.6 mmol/l glucose, unlike in similarly treated wild-type islets
• in contrast to Metabolex 36, docosahexaenoic acid (DHA, 50 or 100 umol/l)) fails to attenuate glucose-induced somatostatin secretion from both wild-type and mutant islets in the presence of 16.6 mmol/l glucose

homeostasis/metabolism
• in the presence of 16.6 mmol/l glucose, DHA (an n-3 fatty acid, 50 or 100 umol/l) fails to increase insulin secretion from mutant islets in a dose-dependent manner, unlike in similarly treated wild-type islets
