Study of DNA methylation in human pancreatic islets Today type 2 diabetes is a common disease with a worldwide prevalence of 8.3%. The disease is characterised by hyperglycaemia which is a result of insufficient insulin secretion from the beta-cells in the pancreatic islets as well as an insulin resistance seen in the target tissues. Type 2 diabetes is a multifactorial disease with genetic, epigen

The human pancreatic islet methylome and its role in type 2 diabetes Islet dysfunction is central to the development and progression of type 2 diabetes (T2D). Epigenetic modifications are essential for establishing and maintaining cell identity and function in normal circumstances. Exposure to adverse environmental factors may alter the epigenome, and result in changes of gene expression and the r

Novel insights into the role of serotonin in control of beta-cell function Inadequate insulin secretion is a central component in the development of Diabetes Mellitus, resulting from reduced pancreatic β-cell mass, as well as diminished β-cell function. Islet produced 5-hydroxy tryptamine (5-HT) is suggested to regulate insulin secretion and β-cell mass in rodents during pregnancy and in metabolic

Genetic Determinants of obesity in relation to diet, weight gain and mortality Obesity is one of the major health concerns that has reached epidemic proportions globally. It is generally believed to be a result of interactions between genetic and environmental factors. In this thesis we investigated the role of dietary factors in modifying the genetic susceptibility to obesity (papers I to III), s

Coupling mechanisms of insulin secretion - roles of mitochondrial metabolism and cAMP Type 2 diabetes is a disease that increases tremendously in the western world. It is characterized by insulin resistance and defects in insulin secretion. Insulin resistance is tightly linked to obesity, and usually precedes the onset of type 2 diabetes. When insulin resistance develops, the pancreatic beta-cells

Lipid metabolism in the pancreatic beta-cell. Implications for insulin secretion. We have investigated the role of lipid metabolism with regard to beta-cell function and insulin secretion. Lipids are known to play a crucial functional role in the pancreatic beta-cell, where they are essential for adequate hormone release, but may also exert a long-term toxic effect, leading to beta-cell dysfunctio

Genetics of diabetic subtypes There are two major types of diabetes mellitus, Type 1 Diabetes (T1D) and Type 2 Diabetes (T2D), however a number of subtypes have been defined and classified. Maternally Inherited Diabetes and Deafness (MIDD) and Maturity Onset Diabetes of the Young (MODY) are monogenic forms, whereas Latent Autoimmune Diabetes in Adults (LADA) is thought to be a polygenic subtype si

Exploring Positional and Functional Candidate Genes for Type 2 Diabetes 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 unk

Pathophysiology and treatment of defective insulin secretion Defective insulin secretion is a central feature in diabetes mellitus and results from reduced pancreatic beta-cell mass as well as aberrant beta-cell function. The pathophysiology of diabetes is incompletely known, but a strong hereditary component is suggested. This thesis investigates the genetic and cellular basis for impaired insuli

Candidate Genes for Late Diabetic Complications Diabetes mellitus is a group of metabolic diseases characterized by hyperglycemia resulting from defects in insulin secretion, insulin action, or both. The new WHO criteria for classification of diabetes takes into account also clinical stages dividing the diabetic patients into noninsulin requiring (NIR), insulin requiring for control (IRC) and insu

Heritability of blood pressure monogenes and polygenes High blood pressure (BP) is associated with cardiovascular morbidity and mortality. Both genetic and environmental factors are implicated in BP homeostatsis and hypertension development. The aims of the present theisis were: (a) to test if ambulatory BP (ABP) is better than office BP (OBP) to capture the heritable part of BP and if BP variabil

Assessment and Treatment of Impaired Insulin-Secretion and Action in Type 2 Diabetes Type 2 diabetes (T2D) is a disease characterised by varying degrees of defect in insulin secretion and insulin sensitivity and associated with increased morbidity and mortality. Optimal glycaemic control reduces the progression of diabetic complications. Over time, there is a steady deterioration of glycaemic cont

Beta-Cell Dysfunction in Huntington´s Disease Huntington's disease (HD), a fatal neurodegenerative disorder, is associated with an increased risk of diabetes mellitus. The reason for this is unknown, but considering the functional similarities of neurons and the insulin secreting pancreatic β-cell, pathological mechanisms may be shared by both cell types and account for neuronal as well as endocri

The Impact of Ethnicity on type 2 Diabetes Type 2 diabetes mellitus is among the fastest growing diseases in the world. The reported prevalence of T2D appears to differ among various ethnic groups. Although ethnic-related differences in lifestyle factors may account for some of the predisposition to diabetes in various ethnic groups, genetic factors may play a more determinant role.High prevalence

Beta Cell Function: from Human Genetics to Animal Models Beta cell function is an important factor in the development of both Type 1 (T1D) and Type 2 (T2D) diabetes mellitus. T1D is characterized by a primary defect in insulin secretion due to the immune-mediated beta cell destruction, however, the more common T2D beside insulin resistance also include impaired beta cell function as a consequence
