  1. 1. On Nogo signaling regulation

    Författare :Alexandra Trifunovski; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Nogo; Nogo receptor; regulation; neurotrophin; Lingo-1; p75NTR; Troy; synaptic plasticity;

    Sammanfattning : As neuronal development enters its final stages, axon growth becomes restricted. This lack of regenerative capacity is partly due to the non-permissive environment of growth inhibitory proteins. Three such proteins, Nogo, OMgp and MAG bind to the same receptor, the Nogo receptor (NgR) and induce growth cone collapse and axon growth inhibition. LÄS MER

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

    Författare :Silvia Gogg; Göteborgs universitet; []
    Nyckelord :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.;

    Sammanfattning : 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. LÄS MER

  4. 3. Towards a comprehensive modeling framework for studying glucose repression in yeast

    Författare :Linnea Österberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; budding yeast; glucose repression; metabolism; mathematical modelling; signaling;

    Sammanfattning : The yeast Saccharomyces cerevisiae is an important model organism for human health and for industry applications as a cell factory. For both purposes, it has been an important organism for studying glucose repression. LÄS MER

  5. 4. TRAF6, a key regulator of TGFβ-induced oncogenesis in prostate cancer

    Författare :Reshma Sundar; Marene Landström; Carl-Henrik Heldin; Petra Knaus; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TβRI; TGFβ; TACE; TRAF6; PS1; PKCζ; TβRI-ICD; NICD; Smad; non-Smad; prostate cancer; Snail1; MMP; p300; p21; PAI1; ubiquitination; cleavage; ICD; invasion; HES1; signaling; patologi; Pathology;

    Sammanfattning : Prostate cancer is the most common cancer in men, with the incidence rapidly increasing in Europe over the past two decades. Reliable biomarkers for prostate cancer are currently unavailable. Thus, there is an urgent need for improved biomarkers to diagnose prostate cancer at an early stage and to determine the best treatment options. LÄS MER

  7. 5. Studies on molecular mechanisms in calcium signaling and cellular energy consumption

    Författare :Kalaiselvan Krishnan; Hjalmar Brismar; Anders Tengholm; KTH; []
    Nyckelord :ca2 signaling; ATP; PercevalHR; NKA; diabetes; Angiotensin; Biological Physics; Biologisk fysik;

    Sammanfattning : Ion signaling plays fundamental role in cell survival. Na+ and Ca2+ are critical players in ion signaling. Cells spend the major amount of energy to maintain and regulate Na+ and Ca2+ gradients across the cell membrane. Any disruption in cellular energy consumption by plasma membrane ATPases affects ion signaling and vice versa. LÄS MER
