1. 1. Aperiodic Array Synthesis for Telecommunications

   Författare :Carlo Bencivenni; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PtP; mutual coupling; SATCOM; compressive sensing; aperiodic array; density taper; MU-MIMO; maximally sparse array; LoS-MIMO;

   Sammanfattning : Arrays of antennas offer important advantages over single-element antennas and are thus a key part of most advanced communication systems. The majority of current arrays are based on a classical regular layout, which offer simple design criteria despite some limitations. LÄS MER

3. 2. Molecular Regulation of Angiogenesis

   Författare :Sofie Mellberg; Lena Claesson-Welsh; Frank Böhmer; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; endothelial morphogenesis; VEGFR-2; protein tyrosine phosphatase; VE-PTP; PTPRB; endocan; ESM-1; angiogenesis; Molecular medicine; Molekylär medicin;

   Sammanfattning : Angiogenesis, de novo formation of blood vessels from the pre-existing vasculature, is crucial in embryo development, and in processes in the adult such as wound healing and ovulation. Angiogenesis is also involved in pathological conditions such as cancer and chronic inflammatory diseases, which are propagated by dysregulated, excess angiogenesis. LÄS MER

4. 3. T-Cell Protein Tyrosine Phosphatase, a Regulator of the PDGF Signaling Pathway

   Författare :Susann Karlsson; Carina Hellberg; Carl-Henrik Heldin; Bengt Hallberg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PDGF; TC-PTP; receptor trafficking; PK-M2; Medical cell biology; Medicinsk cellbiologi; molekylär cellbiologi; Molecular Cellbiology;

   Sammanfattning : Platelet-derived growth factor (PDGF) is a potent stimulator of cell growth, survival and motility. PDGF exerts its function by binding to specific tyrosine kinase receptors, initiating receptor auotphosphorylation and initiation of specific signaling pathways that regulates the cellular response.

5. 4. Regulation of PDGFRβ signaling 

   Författare :Piotr Wardęga; Johan Lennartsson; Edvard Smith; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PDGF; HD-PTP; Alix; Cbl; Ub; Fer; Y857; Y771; downregulation; degradation; ubiquitination; activation loop; Cell and molecular biology; Cell- och molekylärbiologi; Medical Cell Biology; Medicinsk cellbiologi;

   Sammanfattning : Platelet-derived growth factor (PDGF) isoforms, which bind to closely related a- and b-tyrosine kinase receptors, induce migration, proliferation, survival and differentiation of mesenchymal cells. They signal by the active receptor attracting Src homology 2 (SH2) domain containing proteins, which subsequently initiate a set of signaling pathways. LÄS MER

7. 5. Regulation of Platelet-Derived Growth Factor Receptor Signaling and its Targeting in Cancer Therapy

   Författare :Haisha Ma; Johan Lennartsson; Håkan Axelson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PDGF; PDGFR; Ras; macropinocytosis; Fer; STAT3; HD-PTP; Cbl; ubiquitination; pericyte; vasculature; tumor; ASKA; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

   Sammanfattning : Overactivity of platelet-derived growth factor receptor (PDGFR) is a frequent event in many types of solid tumors. Therefore, it is of great importance to uncover the mechanisms that regulate PDGF/PDGFR signalling, to develop efficient inhibitors targeting this pathway. LÄS MER
