1. 21. Visualization and mesoscopic simulation in systems biology

   Författare :Martin Falk; Thomas Ertl; Germany University of Stuttgart Visualization Research Center; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scientific Visualization; GPGPU; Simulation; Systems Biology; Model Development; Signal Transduction;

   Sammanfattning : Biological cells appear everywhere on earth. They might live on their own as unicellular organism, like bacteria, or might form complex organisms consisting of several thousands or millions of cells. Despite their small size of only a few micrometers, they are complex little miracles. LÄS MER

3. 22. Studies of New Signal Transduction Modulators in Acute Myeloid Leukemia

   Författare :Anna Eriksson; Martin Höglund; Rolf Larsson; Bjørn Tore Gjertsen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute myeloid leukemia; Targeted therapies; Drug development; Tyrosine kinase inhibition; AKN-032; AKN-028; Internmedicin; Internal Medicine;

   Sammanfattning : Acute myeloid leukemia (AML) is a life-threatening malignant disorder with dismal prognosis. AML is characterized by frequent genetic changes involving tyrosine kinases, normally acting as important mediators in many basic cellular processes. LÄS MER

4. 23. Mechanisms of Regulation of the Cell Cycle Inhibitor p21Waf1/Cip1 in TGF-β-Mediated Cell Growth Inhibition

   Författare :Katerina Pardali; Aristidis Moustakas; Carl-Hernrik Heldin; Marikki Laiho; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; TGF-β; cell cycle; p21; Smad; signal transduction; transcription; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

   Sammanfattning : TGF-β is the founding member of a multifunctional family of cytokines that regulate many aspects of cell physiology, including cell growth, differentiation, motility and death and play important roles in many developmental and pathological processes. TGF-β signals by binding to a heterotetrameric complex of type I and type II serine/threonine kinase receptors. LÄS MER

5. 24. Regulation of TGF-β Signaling by Post-Translational Modifications

   Författare :Peter Lönn; Aristidis Moustakas; Carl-Henrik Heldin; Petra Knaus; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TGF-β; Smad; PARP-1; PARG; ALK5; SIK; signal transduction; transcription; post-translational modification; phosphorylation; ubiquitin; ADP-ribosylation; DNA-binding; receptor degradation; Cell and molecular biology; Cell- och molekylärbiologi; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

   Sammanfattning : Transforming growth factor-β (TGF-β) signaling is initiated when the ligand binds to type II and type I serine/threonine kinase receptors at the cell surface. Activated TGF-β type I receptors phosphorylate R-Smads which relocate, together with co-Smads, to the cell nucleus and regulate transcription. LÄS MER

7. 25. Lysophosphatidic acid : Physiological effects and structure-activity relationships

   Författare :Ulrika K. Nilsson; Samuel Svensson; Karin E. Bornfeldt; Linköpings universitet; []
   Nyckelord :Lysophospholipids pharmacology; physiology; structure-activity relationship; muscle; smooth; drug effects; myometrium; norepinephrine; epinephrine; signal transduction; MEDICINE; MEDICIN;

   Sammanfattning : Lipids havepreviously been considered primarily as building blocks of the cell membrane, but are now also recognized as important cell signaling molecules. Lysophosphatidic acid (LPA) is a glycerophospholipid consisting of a phosphate head group, a linker region, and a lipophilic tail. LÄS MER
