2. 11. ADP regulation of insulin secretion and beta-cell apoptosis

   Author : Chanyuan Tan; Kardiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; P2Y; β-cell; ADP; insulin; apoptosis; autocrine; ectonucleotidase;

   Abstract : The aims of this dissertation were to investigate the effects of extracellular purines on insulin secretion, and apoptosis in mouse pancreatic islets and β-cells; to examine if high glucose and free fatty acids induces β-cell apoptosis via autocrine effects of ADP acting on the P2Y13 receptor; and to investigate the modulation of extracellular purines in vascular smooth muscle cells (VSMCs) through ectonucleotidase or ATP release under the effect of high glucose. The expression of the ADP receptors P2Y1 and P2Y13 were shown in both mouse pancreatic islets and isolated β-cells using real-time PCR quantification. READ MORE

4. 12. Exploring Positional and Functional Candidate Genes for Type 2 Diabetes

   Author : Johan Holmkvist; diabetes och endokrinologi Genomik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi; MODY; type 2 diabetes; Endocrinology; calcium channel; insulin secretion; insulin; single nucleotide polymorphism SNP glucose; linkage disequilibrium; genetic association; genetics;

   Abstract : Type 2 diabetes (T2D) is a complex, metabolic disorder characterized by hyperglycaemia because of defects in insulin secretion and sensitivity. The rapid increase in T2D is likely to reflect the influence of both genetic and environmental factors in disease development. However, the genetic aetiology of T2D remains largely unknown.

5. 13. THE ROLE OF PHOSPHODIESTERASE 3B IN CAMP-MEDIATED REGULATION OF INSULIN SECRETION

   Author : Helena Jones; Signaltransduktionsforskning; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cAMP; PDE3B; exocytosis; insulin; diabetes; Medicine human and vertebrates ; Medicin människa och djur ; diabetologi; sekretion; Endokrinologi; diabetology; Endocrinology; secreting systems;

   Abstract : Type 2 diabetes mellitus (T2DM) is characterized by various combinations of ?-cell failure and insulin resistance leading to hyperglycemia and glucose intolerance. In order to maintain glucose tolerance in the insulin resistance state, increased insulin secretion is a requirement and it is because of inadequate islet adaptation that glucose intolerance develops in T2DM.

6. 14. Protein kinases in hormonal regulation of adipocyte metabolism

   Author : Christine Berggreen; Proteinfosforylering; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adipocyte; PKB; AMPK; SIK3; insulin; catecholamines; lipolysis; lipogenesis; glucose uptake; de novo fatty acid synthesis; A769662; Akti; cAMP;

   Abstract : Abstract Along with liver and muscle tissue, adipose tissue helps maintain normal levels of glucose and lipids in the blood and has a very important role when it comes to storing lipids that can provide whole-body energy. After a meal is ingested, adipocytes take up glucose from the circulation and use it as a substrate for synthesis of new fatty acids (FAs) in a process known as de novo fatty acid synthesis, as well as for synthesis of glycerol.

7. 15. Metabolic impact of certain dietary proteins and/or amino acids - Glycaemic and hormonal responses to carbohydrate meals in healthy subject

   Author : Ulrika Gunnerud; Avdelningen för livsmedel och läkemedel; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amino acids; dietary protein; glycaemic regulation; insulin; incretins;

   Abstract : Re-occurring hyperglycaemic episodes promote subclinical low-grade inflammation and CVD in type 2 diabetes, emphasising the therapeutic role of tight blood glucose regulation. A tight blood glucose regulation is probably beneficial also in healthy subjects and mild elevations in postprandial glycaemia and triglycerides are associated with impaired flow-mediated dilation and increased markers of oxidative stress in young healthy subjects.
