2. 1. Fat cell insulin resistance : an experimental study focusing on molecular mechanisms in type 2 diabetes

   Author : Frida Renström; Jan Eriksson; Anna Krook; Umeå universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; adipocyte; insulin signaling; insulin; glucose; IRS-1; glucose uptake; insulin resistance; typ 2 diabetes; serum; Medicine; Medicin;

   Abstract : The aim of the present thesis was to further increase our understanding of mechanisms contributing to and maintaining cellular insulin resistance in type 2 diabetes (T2D). For this reason, the effects of high glucose and insulin levels on glucose transport capacity and insulin signaling, with emphasis on insulin receptor substrate 1 (IRS-1) were assessed in fat cells.

4. 2. Evolutionary Analysis of the Insulin-Relaxin Gene Family from the Perspective of Gene and Genome Duplication Events

   Author : Robert Piotr Olinski; Finn Hallböök; Mike Thorndyke; Pierre Pontarotti; Uppsala universitet; []
   Keywords : Neurosciences; insulin; relaxin; insulin-like protein; gene duplication; paralogous region; Ciona intestinalis; conserved synteny; ortholog; Drosophila melanogaster; Neurovetenskap;

   Abstract : Paralogs arise by duplications and belong to families. Ten paralogs (insulin; IGF-1 and -2; INSL3-6 and 3-relaxins) constitute the human insulin-relaxin family. The aim of this study was to outline the duplications that gave rise to the vertebrate insulin-relaxin genes and the chromosomal regions in which they reside. READ MORE

5. 3. Regulation of intracellular signaling events that modulate insulin action

   Author : Silvia Gogg; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; insulin; insulin resistance; EGF; Gab 1; insulin receptor substrate; PI3-kinase; ; Thiazolidinediones; PPARã; insulin signaling; glucose transport; adipose tissue; â-cell.;

   Abstract : Insulin regulates several mechanisms of fundamental importance to the body involving glucose, fat andprotein metabolism. Insulin resistance in skeletal muscle, liver and adipose tissue promotes an increaseddemand for insulin secretion. READ MORE

6. 4. Glucose- and hypoxia-regulated insulin gene expression

   Author : Linda Tillmar; Jens Höiriis Nielsen; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; islet; beta-cell; insulin; mRNA stability; PTB; glucose; hypoxia; mTOR; p70s6k; ceramide; redox; ROS; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

   Abstract : Although extensively studied, there are still many unanswered questions regarding the exact regulation of insulin gene expression. This is important to further investigate since it will hopefully help us understand the pathophysiology of some types of diabetes. READ MORE

7. 5. Membrane rafts and its GPI anchored complement inhibitors regulate insulin secretion

   Author : Vini Nagaraj; Diabetes - öpatofysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Membrane rafts; basal insulin secretion; regulated insulin secretion; CD59; CD55; SNARE proteins; insulin; pancreatic beta cells.;

   Abstract : Type 2 diabetic patients usually exhibit an abnormal lipid profile. One such lipid that is constantly elevated in T2D is cholesterol. At the cellular level, cholesterol aids in tight packing of sphingolipids in certain regions of the plasma membrane and these specialized regions are termed ‘membrane rafts’, which act as signalling hubs.
