  1. 1. Calcium regulation and functions of basic Helix-Loop-Helix transcription factors

    University dissertation from Umeå : Molekylärbiologi

    Author : Juha Saarikettu; Umeå universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; calcium; calmodulin; calretinin; transcription; bHLH; E-protein; E2-2; Molekylärbiologi; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The members of the ubiquitously expressed E-protein subfamily of basic Helix-Loop-Helix (bHLH) transcription factors, E12/E47, SEF2-1 and HEB, have important roles as regulators of gene expression in various differentiation processes, including lymphocyte development and myogenesis. In myogenesis, E-proteins are proposed to function as obligate heterodimer partners for members of the MyoD family of muscle-specific bHLH transcription factors. READ MORE

  2. 2. Regulation and functions of basic helix-loop-helix transcription factors in neuroblastoma cells

    University dissertation from Paula Persson, Skvadronsg 27, 217 49 Malmö

    Author : Paula Persson; Lund University.; Lunds universitet.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; Cytology; Id; Olf EBF; ubiquilin-1; HASH-1; bHLH; Neuroblastoma; neuronal differentiation; cancer; onkologi; cancerology; Cytologi;

    Abstract : Neuroblastoma is a childhood tumor derived from primordial neural crest cells. The tumor cells exhibit a phenotype similar to that of developing neuroblasts, which indicates that the tumor arises due to perturbed differentiation of the sympathetic nervous system. READ MORE

  3. 3. Polypeptide-Based Nanoscale Materials

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Daniel Aili; Linköpings universitet.; Linköpings universitet.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gold nanoparticle; polypeptide; helix-loop-helix; four-helix bundle; self-assembly; folding; MEDICINE Chemistry; MEDICIN Kemi;

    Abstract : Self-assembly has emerged as a promising technique for fabrication of novel hybrid materials and nanostructures. The work presented in this thesis has been focused on developing nanoscale materials based on synthetic de novo designed polypeptides. READ MORE

  4. 4. Cell cycle genes in chondrosarcoma. Involvement of the Id1 and p16 pathways

    University dissertation from Göteborg

    Author : Julia Asp; Göteborgs universitet.; Gothenburg University.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chondrosarcoma; articular chondrocytes; cell cycle; p16; Id1; helix-loop-helix;

    Abstract : Chondrosarcoma is a malignant, cartilaginous tumour arising from bone. The wide variationin morphology, behaviour and clinical outcome raise the question whether chondrosarcomasare several different but closely related tumours rather than a single entity. READ MORE

  5. 5. The immunoglobulin heavy chain 3 enhancer : coupling of basic-Helix-Loop-Helix proteins to the regulation of enhancer function

    University dissertation from Stockholm : Karolinska Institutet, false

    Author : Velmurugesan Arulampalam; Karolinska Institutet.; Karolinska Institutet.; [1996]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : During B lymphocyte development, the transcriptional activity of the IgH locus is subject tospatial and temporal changes. One cis-control element, the IgH 3' enhancer, has been impli-cated in regulating functional events in late B cell development. READ MORE
