39. Metabotropic glutamate and GABAB receptors contribute to the modulation of glucose-stimulated insulin secretion in pancreatic beta cells.

Abstract

Aims/hypothesis: The neurotransmitters glutamate and γ-aminobutyric acid (GABA) could participate in the regulation of the endocrine functions of islets of Langerhans. We investigated the role of the metabotropic glutamate (mGluRs) and GABAB (GABABRs) receptors in this process. Methods: We studied the expression of mGluRs and GABABRs in rat and human islets of Langerhans and in pancreatic α-cell and beta-cell lines using RT-PCR and immunoblot analysis. Effects of mGluR and GABABR agonists on insulin secretion were determined by radioimmunoassays and enzyme-linked immunoadsorbent assays (ELISAs). Results: We detected mGluR3 and mGluR5 (but not mGluR1, 6 and 7) mRNAs in all of the samples examined. Trace amount of mGluR2 was found in MIN6 beta cells; mGluR4 was identified in rat islets; and mGluR8 expression was detected in rat islets, RINm5F and MIN6 cells. GABABR1 a/b and 2 mRNAs were identified in islets of Langerhans and MIN6 cells. The expression of mGluR3, mGluR5, GABABR1 a/b and GABABR2 proteins was confirmed using specific antibodies. Group I (mGluR1/5) and group II (mGluR2/3) specific mGluR agonists increased the release of insulin in the presence of 3 to 10 mmol/l or 3 to 25 mmol/l glucose, respectively, whereas a group III (mGluR4/6–8) specific agonist inhibited insulin release at high (10–25 mmol/l) glucose concentrations. Baclofen, a GABABR agonist, also inhibited the release of insulin but only in the presence of 25 mmol/l glucose. Conclusion/interpretation: These data suggest that mGluRs and GABABRs play a role in the regulation of the endocrine pancreas with mechanisms probably involving direct activation or inhibition of voltage dependent Ca2+-channels, cAMP generation and G-protein-mediated modulation of KATP channels.

40. Nesidioblastosis of the pancreas: definition of the syndrome and the management of the severe neonatal hyperinsulinaemic hypoglycaemia.

Abstract

Three newborn infants are reported who developed severe non-ketotic hypoglycaemia (blood glucose less than 1.1 mmol/l; 19.8 mg/100 ml) within 6 hours of birth. All had inappropriately raised plasma insulin concentrations for the level of glycaemia, and required high rates of glucose infusion (less than 15 mg glucose/kg per minute) to prevent symptoms of hypoglycaemia. Medical treatment (hydrocortisone, diazoxide, chlorothiazide, phenytoin, propranolol, and depot glucagon) was ineffective in preventing hypoglycaemia and all 3 infants were subjected to partial and then total pancreatectomy. The pathological features of nesidioblastosis are reported from quantitative immunohistochemical studies on the pancreata. These results together with those from metabolic and endocrine studies performed on the 3 infants during the investigation of the cause of the hypoglycaemia and during the preoperative and postoperative period are presented in detail in order to define a practical approach to the management of this difficult clinical problem in the neonate.

Abstract

We report on the stimulatory effect of creatine on insulin secretion and ATP concentration in MIN-6 beta-cells. The addition of creatine (5 mM) to MIN-6 cells in the presence of glucose (1-10 mM) elicited a significant (p<0.001) increase in insulin secretion, but no effect was demonstrated in the absence of glucose. The lack of effect of creatine in the absence of glucose suggests that creatine may act as a potentiator of insulin secretion rather than as an initiator. The potentiatory effect of creatine is specific for glucose since no effect was found in the presence of other known initiators of insulin secretion (K(+), 2-ketoisocaproic acid and tolbutamide). Cellular ATP content was markedly increased by glucose (1-15 mM). Creatine (5 and 10 mM) further increased the ATP level at all glucose concentrations, and the effect was observed even in the absence of glucose. The results from this study demonstrate the ability of creatine to increase insulin secretion only in the presence of glucose, while its effect on increased cellular ATP was independent of the presence of glucose. The mechanism whereby creatine potentiates insulin release is yet to be investigated. However, our data suggest possible unique interactions between creatine and the glucose-dependent insulin secretory pathway.
