  1. 1. Regulation of DNA damage responses by the Myc oncogene : implications for future anti-cancer therapies

    Författare :Andreas Höglund; Jonas Nilsson; Thomas Helleday; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Myc; DNA damage; Decitabine; Chk1; Chk2; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Myc is a transcription factor frequently found deregulated in human cancer. Cells with deregulated expression of Myc carry a selective advantage against its neighbours due to the fact that Myc-mediated transcription governs crucial cellular events such as proliferation and growth.

  3. 2. Prognostic and Treatment Predictive Markers Associated with Cyclin D1 Gene Amplification and Epithelial-Mesenchymal Transition in Breast Cancer

    Författare :Katja Lundgren; Malmö Patologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; beta-arrestin1; Chk1; Breast Cancer; Tamoxifen; prognostic marker; predictive marker; gene amplification; cyclin D1; EMT; Snail; hypoxia;

    Sammanfattning : Endocrine resistant breast cancer is a major therapeutical challenge and accurate selection of patients susceptible to certain types of anti-hormonal treatment strategies is pivotal. Discovery of novel biomarkers potentially predicting treatment response as well as the clinical course of breast cancer is essential to effectively improve therapies and diagnosis. LÄS MER

  4. 3. The role of RNA-binding motif 3 in epithelial ovarian cancer: A biomarker discovery approach

    Författare :Åsa Ehlén; Malmö Patologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; DNA integrity checkpoint; cisplatin treatment; prognostic predictive marker; RBM3; epithelial ovarian cancer; Chk1; Chk2; MCM3;

    Sammanfattning : Epithelial ovarian cancer (EOC) is the most lethal of all gynaecological malignancies and there is an urgent need to develop new prognostic and treatment predictive biomarkers for a more efficient therapy. The discovery of the RNA-binding motif protein 3 (RBM3) as a putative cancer biomarker was based on its differential expression in various cancer forms in the Human Protein Atlas (HPA). LÄS MER

  5. 4. Replication Fork Stability in Mammalian Cells

    Författare :Ingegerd Elvers; Thomas Helleday; Jan H. J. Hoeijmakers; Stockholms universitet; []
    Nyckelord :replication fork progression; replication fork stability; re-priming; DNA damage signalling; NATURAL SCIENCES; NATURVETENSKAP; molekylärgenetik; Molecular Genetics;

    Sammanfattning : Maintaining replication fork integrity is vital to preserve genomic stability and avoid cancer. Physical DNA damage and altered nucleotide or protein pools represent replication obstacles, generating replicative stress. Numerous cellular responses have evolved to ensure faithful DNA replication despite such challenges. LÄS MER

  7. 5. DNA precursor asymmetries, Mismatch Repair and their effect on mutation specificity

    Författare :Robert Buckland; Andrei Chabes; Juan Méndez; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; DNA Replication Fidelity; Mutations; dNTP pools; Mismatch Repair; Checkpoint; Ribonucleotide Reductase; Msh2; medicinsk biokemi; Medical Biochemistry; molekylärbiologi; Molecular Biology;

    Sammanfattning : In order to build any structure, a good supply of materials, accurate workers and quality control are needed. This is even the case when constructing DNA, the so-called “Code of Life.” For a species to continue to exist, this DNA code must be copied with incredibly high accuracy when each and every cell replicates.
