1. Roles of voltage-gated Ca2+ channel subunits in pancreatic β cells
Abstract : Hallmarks of type 2 diabetes (T2D) include elevated blood glucose and free fatty acids (FFAs) as a result of impaired β cell insulin secretion and decreased β cell mass. The glucose-stimulated insulin secretion (GSIS) in β cells is triggered by depolarization-evoked Ca2+ entry through voltage-gated Ca2+ (CaV) channels. READ MORE

2. 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

3. Effects of Ca2+, microRNAs, and rosuvastatin on insulin-secreting beta cell function
Abstract : Type 2 diabetes (T2D) is a condition of high blood glucose levels due to insulin resistance and defective insulin secretion. Impaired insulin secretion plays a major role in the pathophysiology of T2D, it is mainly attributed to beta cell function i.e. failure to secrete insulin or reduced beta cell mass. READ MORE

4. Regulation of exocytosis by Ca2+ and cAMP - A study on pancreatic beta- and alpha-cells
Abstract : Type-2 diabetes is characterized by impaired insulin secretion associated with excess glucagon release. Exocytosis of insulin- or glucagon-containing granules is initiated by Ca2+-influx through voltage-dependent Ca2+-channels and is modulated by the second messengers such as cAMP. READ MORE

5. Regulation of glucagon secretion from pancreatic alpha cells
Abstract : Glucagon secreted by pancreatic α-cells plays an important role in the regulation of blood glucose. In this thesis, different techniques such as electrophysiology, immunohistochemistry and hormone secretion assay were combined to explore the mechanisms by which glucagon secretion is regulated.
