  2. 1. Protein tyrosine kinases in insulin producing cells : Expression and putative importance for beta-cell function

    Author : Charlotte Öberg-Welsh; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Protein tyrosine kinase; insulin producing cells; fetal development; VEGF; Src-family; Bsk; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : Protein tyrosine kinases are of importance for cell replication and differentiation in manysystems. The mechanisms controlling the replication and differentiation of insulin producingcells are unknown. READ MORE

  4. 2. 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

  5. 3. Insulin-Producing Cells, Iron, Oxidative Stress, and Lysosomal Pathology

    Author : Beata Teresa Olejnicka; Enrique Cadenas; Linköpings universitet; []
    Keywords : Insulin-producing cells; redox-active iron; oxidative stress; lysosomes; desfenioxamine; MEDICINE; MEDICIN;

    Abstract : Accumulating evidence suggests that injnries caused by oxygen-derived radicals contribute to the destruction of pancreatic islet ß-cells in autoinnnune diabetes mellitus (diabetes type I, or IDDM). Oxidative stress may be caused by an enhanced production of oxygen-derived radicals, or by a decreased scavenging of such molecules. READ MORE

    Author : Eva Pålsgård; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : .... READ MORE

  7. 5. Regulation of cytokine-induced nitric oxide production in insulin-producing cells

    Author : Malin Flodström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Diabetes; pancreatic islets; insulin-producing cells; cytokines; nitric oxide; inducible nitric oxide synthase; nuclear factor-kappaB; interferon regulatory factor-1; arginine; citrulline; argininosuccinate synthetase; insulin release; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : Cytokine-induced expression of the inducible form of nitric oxide synthase (iNOS) and production of nitric oxide (NO) may contribute to pancreatic β-cell damage during the development of type 1 diabetes. iNOS catalyses the conversion of arginine into citrulline and NO, a reaction regulated by the amount of expressed iNOS enzyme and by the cellular availability of arginine.
