  2. 6. Gene expression and its physiological control in disease and development : Studies on the human PDGF-B gene and tumour hypoxia

    Author : Erik Ullerås; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Zoologisk utvecklingsbiologi; Animal Development;

    Abstract : Strict control of gene expression is essential during development and in response to physiological stimuli. This thesis describes the functional characterisation of the gene regulatory mechanisms controlling the expression of the potent human growth factor Platelet Derived Growth Factor B gene, in a cell type specific context and in response to low oxygen tension.

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

    Author : Giulia Pizzolato; Stefan Koch; Åsa Keita; Boudewijn Burgering; Linköpings universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 8. Oncolytic Adenovirus Therapy of Neuroendocrine Tumors

    Author : Justyna Leja; Magnus Essand; Valeria Giandomenico; Akseli Hemminki; Uppsala universitet; []

    Abstract : Neuroendocrine tumors (NETs), originally described as carcinoids, represent a rare and heterogeneous group of neoplasms associated with intensive secretion of hormones, bioactive peptides and amines. Most of the patients are diagnosed at a late stage of disease, often with liver metastases. READ MORE

  6. 9. Molecular Genetic Analysis in B-cell Lymphomas : A Focus on the p53 Pathway and p16INK4a

    Abstract : The presence of TP53 mutations has been associated with inferior outcome in diffuse large B-cell lymphoma (DLBCL) and chronic lymphocytic leukemia (CLL). In DLBCL, the impact of the TP53 codon 72 polymorphism and MDM2 SNP309 has not been clearly elucidated, whereas MDM2 SNP309 was suggested as a poor-prognostic marker in CLL. READ MORE

  7. 10. Regulation of apoptosis during treatment and resistance development in tumour cells

    Author : Jeanette Blomberg; Erik Lundgren; John Eriksson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tumörbiologi; Tumour biology; Tumörbiologi;

    Abstract : Induction of apoptosis is the most studied cell death process and it is a tightly regulated physiological event that enables elimination of damaged and unwanted cells. Apoptosis can be induced via activation of either the intrinsic or the extrinsic signalling pathway. READ MORE
