  2. 1. The impact of glucotoxicity on pancreatic β-cell function

    Author : Sarheed Jabar Muhammed; Islet cell physiology; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cAMP PKA system; iNOS; Type 2 diabetes; GSIS; PDE; GK rat; ZDF fa fa rat; GPR40; VDAC1; VDAC2; GSK-3β; ChREBP; TXNIP; resveratrol.;

    Abstract : Type 2 diabetes mellitus is connected with elevated plasma glucose levels which negatively influence β-cells and cause impaired glucose-stimulated insulin secretion (GSIS). The aim of present thesis was to investigate the impact of long-term hyperglycemia on the pancreatic islet β-cell function. READ MORE

  4. 2. FGFs and Wnts in pancreatic growth and β-cell function

    Author : Stella Papadopoulou; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Wnt; FGF; pancreas; Notch; signal transduction; development; proliferation; progenitors; β-cells; feedback; GSIS; diabetes; Molekylärbiologi; Molecular biology; Molekylärbiologi;

    Abstract : Mesenchymal-epithelial interactions are pivotal for proper pancreatic growth and development. The pancreatic progenitor cells present in the early pancreatic anlagen proliferate and eventually give rise to all pancreatic cell types. READ MORE

  5. 3. Glucotoxicity in Insulin-Producing β-Cells

    Author : Hanna K Nyblom; Peter Bergsten; Michael Welsh; Miriam Cnop; Uppsala universitet; []
    Keywords : Cell biology; type 2 diabetes; SELDI-TOF MS; glucotoxicity; proteomics; insulin secretion; mitochondria; lipids; INS-1E cells; GC-MS; HR-MAS NMR; metabolomics; human islet; AMPK; AICAR; ER stress; apoptosis; Cellbiologi;

    Abstract : Background and aims: Type 2 diabetes mellitus is connected with elevated glucose levels, which cause impaired glucose-stimulated insulin secretion (GSIS) and degeneration of β-cells. Mechanisms for such glucotoxic effects were explored in the present study.Materials and methods: INS-1E cells were cultured for 5 days in 5. READ MORE

  6. 4. Nitric Oxide Synthase in Pancreatic Islets During Trauma and Parenteral Feeding

    Author : Saleem Qader; Islet cell physiology; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi; Gastroenterologi; Gastro-enterology; Pancreatitis; Ghrelin; TPN; cNOS; iNOS; PACAP; VIP; cAMP; Pancreatic islets; Insulin secretion;

    Abstract : The influence of trauma (acute pancreatitis) or total parenteral nutrition (TPN) on pancreatic islet hormone secretion in relation to islet expression of inducible nitric oxide synthase (iNOS) was investigated. Acute pancreatitis resulted in an impaired glucose-stimulated insulin secretion (GSIS) which was found to be parallelled by a marked expression of iNOS and an exaggerated NO production in the pancreatic islets.

  7. 5. Non-coding RNAs in beta cell insulin secretion - emerging players in Type 2 Diabetes pathogenesis

    Author : Jones Ofori; Diabetes - öcellsexocytos; []
    Keywords : T2D; insulin secretion; exocytosis; ncRNAs; GAS5; miR-152; miR-335; miR-130a b; miR-375; STXBP1; SNAP25; SYT13; PDHA1; PDX1; glucocortiocoid; beta cell function; glucose metabolism;

    Abstract : Type 2 diabetes (T2D) is a complex polygenic disease influenced by both environmental and genetic factors resulting in impaired insulin release from pancreatic beta cells and insulin resistance in target tissues. The incidence of T2D is escalating and it is projected that over 640 million people will be affected by 2040. READ MORE
