1. Islet hormonal hypersecretion and metformin’s effect on islet hormonal secretion studied in vitro and in vivo
Abstract : Childhood obesity has surged globally. Elevated levels of free fatty acids contribute to hyperinsulinemia, hyperproinsulinemia, and hyperglucagonemia connected with both obesity and type 2 diabetes mellitus (T2DM). Metformin has beneficial effects on islets by influencing metabolism and reducing stress-induced cell death. READ MORE

2. Pancreatic extracellular communication. Applications to beta cell cultures and islet amyloid polypeptide aggregation
Abstract : Diabetes mellitus (DM) is a disease with epidemic proportions due to increased incidences worldwide, persistence of undiagnosed cases, uncontrolled forms of the disease, association with cardiovascular complications, and lack of definitive treatment options. In particular, type 2 DM (T2DM) is placing an enormous financial burden on worldwide healthcare systems that will increase in the futureThere is a need to develop physiological assay platforms that provide functionally relevant models of diabetes in order to accelerate the discovery of new treatments.

3. Ion channel control of phasic insulin secretion
Abstract : Glucose-stimulated insulin secretion exhibits a biphasic pattern. The mechanism underling biphasic insulin secretion is not fully understood, but consensus exists that an elevation in [Ca2+]i is required for both first- and second-phase insulin secretion. READ MORE

4. Oscillatory Signaling and Insulin Secretion from Single ß-cells
Abstract : cAMP and Ca2+ are key regulators of exocytosis in many cells, including insulin-secreting pancreatic β-cells. Glucose-stimulated insulin secretion from β-cells is pulsatile and driven by oscillations of the cytoplasmic Ca2+ concentration ([Ca2+]i), but little is known about the kinetics of cAMP signaling and the mechanisms of cAMP action.

5. On Cholecystokinin and Phospholipase A2 in Insulin Secretion - an Experimental Study With Reference to the Development of Diabetes
Abstract : In view of unsolved issues regarding cellular events underlying the adaptation of insulin secretion to insulin resistance, together with the observation that insulin secretion induced by the gastrointestinal hormone and neuropeptide cholecystokinin (CCK) is not solely explained by phospholipase C-protein kinase C (PLC-PKC) pathway activation, this study aimed at delineate mechanisms responsible for the hyperinsulinemia in insulin resistance, with particular attention paid to the action of glucose vs. non-glucose secretagogues, such as CCK.
