  1. 1. Notch signalling in carcinogenesis : With special emphasis on T-cell lymphoma and colorectal cancer

    Författare :Jonas Ungerbäck; Peter Söderkvist; Ola Hermanson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Notch signalling; T-cell lymphoma; colorectal cancer; Wnt signalling; transcription; Medical cell biology; Medicinsk cellbiologi;

    Sammanfattning : The Notch signalling pathway is an evolutionary conserved pathway, named after the Notch receptors, Notch1-4 in mammals, which upon cell-cell contact and ligand binding releases the intracellular domain (NICD). NICD translocates into the nucleus where it binds the transcriptional repressor RBP-Jk, which together with co-activators belonging to the Mastermind-like family of proteins form a transcriptional activation complex.

  3. 2. Wnt-5a Signalling in Human Mammary Cells: Implications for the Development of Breast Cancer

    Författare :Marzieh Jönsson; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; Cytology; signalling; breast cancer; Wnt-5a; mammary epithelial cells; cancer; onkologi; Cytologi; cancerology;

    Sammanfattning : The Wnt-5a gene encodes a secreted protein that regulates several normal processes in embryonic and adult tissues by as yet unknown mechanisms. Expression of Wnt-5a protein does not cause cell transformation, but it instead counteracts the effects induced by transforming Wnts. LÄS MER

  4. 3. Molecular characterization of FOX factors and Wnt signalling interplay in human cancers

    Författare :Giulia Pizzolato; Stefan Koch; Åsa Keita; Boudewijn Burgering; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; FOX proteins; Wnt signalling; p53; Tumour biology; Transcription factors; Proteine FOX; Via di segnalazione Wnt; p53; Biologia dei tumori; Fattori di trascrizione;

    Sammanfattning : Wnt/β-catenin signalling, also referred to as canonical Wnt signalling, is a critical regulator of tissue homeostasis and of the differentiation of cells during development. The outcome of canonical Wnt pathway activity is defined by the regulation of target gene transcription, which ultimately determines cell identity and proliferation. LÄS MER

  5. 4. Effects of cytokines on preadipocyte differentiation and Wnt signalling

    Författare :Birgit Gustafson; Göteborgs universitet; []
    Nyckelord :adipocyte differentiation; adiponectin; beta-Catenin; C EBPalpha; IL-6; PPARgamma; TNFalpha; Wnt signalling;

    Sammanfattning : The relationship between amount of adipose tissue, the Metabolic Syndrome and Type 2 diabetes has been recognized for several years. However, the mechanisms for this remain to be clarified. Not all obese individuals develop insulin resistance or Type 2 diabetes and these perturbations are also seen in non-obese individuals.

  7. 5. On the role of signaling pathways in the pathogenesis of osteoarthritis

    Författare :Johan Stenberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osteoarthritis; Signalling pathways; proteomics; genomics; GDF5; Wnt;

    Sammanfattning : The problem with degenerating cartilage tissues is one of the major causes for disability worldwide. The aetiology of the cartilage degenerating disease osteoarthritis is elusive and considered to be multifactorial. The aim of the present thesis was to find new hypotheses regarding the aetiology of osteoarthritis with focus on signalling pathways. LÄS MER
