  2. 1. Studies of cAMP and Ca2+ signaling in pancreatic islet cells

    Author : Hongyan Shuai; Anders Tengholm; Erik Gylfe; Sebastian Barg; Albert Salehi; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pancreatic islet; insulin; glucagon; somatostatin; pancreatic polypeptide; exendin- 9-39 ; GLP-1; GIP; ATP; adenosine; cAMP; Ca2 ; β-cell; α-cell; δ-cell; PP-cell;

    Abstract : The blood glucose-lowering and -elevating hormones insulin and glucagon are released from the pancreatic islet β- and α-cells, respectively. The intracellular messengers Ca2+ and cAMP have central roles in controlling the secretion of both hormones, but the underlying mechanisms are incompletely understood. READ MORE

  4. 2. Cell fate specification by Ras-mediated cell signalling in C. elegans

    Author : Teresa Tiensuu; Simon Tuck; Benjamin Podbilewicz; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; cell signalling; Ras; vulva precursor cell; lin-25; sur-2; lin-1; cell fate specification; Mediator; vulva induction; transcriptional regulation; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

    Abstract : Induction of vulval fates in the C. elegans hermaphrodite is mediated by a conserved RTK/Ras/MAP kinase signalling pathway, in which the core components can be placed into a linear genetic and biochemical pathway. However, the events that occur downstream of this pathway are not yet well understood. READ MORE

  5. 3. The diverse functions of the ADAR enzymes : Editing and editing-independent effects on gene expression

    Author : Victor Karlström; Neus Visa; Ayelet Lamm; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; RNA editing; ADAR; Alternative splicing; miRNA processing; neuronal differentiaton; molekylär biovetenskap; Molecular Bioscience;

    Abstract : The adenosine deaminase acting on RNA (ADAR) family of enzymes consists of three members (ADAR1-3). These enzymes are responsible for the deamination of adenosine into inosine in double-stranded RNA, one of the most common RNA modifications in mammals. READ MORE

  6. 4. Physiological roles of amyloid precursor protein in vivo - zebrafish as a model

    Author : Jasmine Chebli; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amyloid-beta precursor protein; amyloid precursor protein-b; zebrafish; physiological functions; development; trigeminal ganglia; ependyma; cilia; proteomics; translational adaptation;

    Abstract : Amyloid-beta precursor protein (APP) is an evolutionarily conserved transmembrane protein expressed in many different tissues. APP belongs to a gene family consisting of two other APP-like proteins (APLP1 and APLP2). READ MORE

  7. 5. To be or not to be, unraveling molecular mechanisms for lineage decisions in developing blood cells

    Author : Robert Månsson; Stamcellscentrum (SCC); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematologi; extracellular fluids; Haematology; common lymphoid precursor CLP ; early B-cell factor 1 EBF1 ; B-cell; Stemcell; hematopoiesis; extracellulära vätskor; Immunology; serology; transplantation; Immunologi; serologi;

    Abstract : All hematopoietic cells originate from hematopoietic stem cells (HSC) residing in the BM. The process of differentiation, through which HSCs generate progenitors and subsequently mature blood cells has been extensively studied but many of the regulatory mechanisms involved remains elusive.
