Energy Homeostasis During Fasting and Fed States: Foxa2 Regulates Hepatic Amino Acid Uptake
… -/- mouse, there is a defect in arginine-induced insulin secretion. In this thesis, we examined the role of arginine transporters in the insulin secreting cells in arginine-induced insulin secretion. We first characterized arginine uptake by MIN6 cells as having a Km of 102.6 μM and being …

Exocytosis in Type 2 Diabetes- Functional and genetic studies of hormone secretion
… essential for cAMP-dependent rapid exocytosis in insulin-secreting cells, and that the effect may be mediated by binding to cAMP-GEFII (paper I). In mouse alpha-cells, SNAP25 and Stx1A display a glucose-dependent localization where immunoneutralization of SNAP25 and Stx1A strongly reduce the …

Somatic cell gene therapy for diabetes mellitus: engineering a surrogate B-cell
Improved methods of insulin delivery are required for the treatment of insulin-dependent diabetes mellitus (IDDM) to achieve a more physiological profile of glucose homeostasis. Somatic cell gene therapy offers the prospect that insulin could be delivered by an autologous cell implant, engineered …

Baicalein, a novel anti-diabetic compound
… inadequate mass and progressive dysfunction of ?-cells, leading to the impaired insulin secretion. Thus, the search for agents to protect b-cell and enhance its function is important for diabetes treatment. Studies have reported that baicalein, a flavone originally isolated from the roots of …

Regulation of Insulin and CHOP Gene Expression in Pancreatic Beta Cells
Insulin is a major hormone in maintaining glucose homeostasis. It is essential to understand the mechanisms by which insulin gene expression is regulated in pancreatic beta cells. In addition to examining histone modifications on the insulin gene promoter, I focused on the effect of MafA …

Novel Roles of Gastrin and Cholecystokinin in Islet Beta Cell Proliferation
… arises from autoimmune destruction of the beta cells. In the latter stages of Type 2 diabetes, there is a precipitous drop in beta cell mass, resulting from the combination of several factors. In the last decade, islet transplantation has re-emerged as a viable option for the treatment of Type 1 …

Search for Insulin Secretion Modulators, Novel Functions of WNK Signaling and Intramolecular Signal Transduction in ERK2
In this dissertation, the regulation of insulin secretion from pancreatic beta cells, WNK1 pathway involvement in cell migration, angiogenesis, breast cancer, and other processes, as well as ERK2 intradomain communication are discussed. Each chapter is dedicated to a separate project, but the …
