  1. 1. Genetic and Epigenetic Characterisation of Breast Tumours

    Författare :Karolina Holm; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast cancer; PIK3CA; PTEN; PI3K pathway; CCND1; microarrays; molecular subtypes; DNA methylation; EZH2; H3K27me3; PRC2; histone modification;

    Sammanfattning : Breast tumours harbour a large amount of genetic and epigenetic alterations, which are associated with e.g. tumour aggressiveness, prognosis, and response to therapy. LÄS MER

  3. 2. Molecular Genetic Studies on Prostate and Penile Cancer

    Författare :Patiyan Andersson; Peter Söderkvist; Mattias Höglund; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; IRS1; penile cancer; hTERT; FHIT; PIK3CA; HRAS; KRAS; NRAS; BRAF; Oncology; Onkologi;

    Sammanfattning : This thesis is comprised of two parts. In the first part we study the influence of four frequently disputed genes on the susceptibility for developing prostate cancer, and in the second part we attempt to establish a basic understanding of the molecular genetic events in penile cancer.

  4. 3. Genomic Profiling, Mutations and Deranged Signaling in Esophageal Cancer and Hereditary Colorectal Cancer

    Författare :Anna Isinger Ekstrand; Institutionen för immunteknologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Esophageal cancer; hereditary cancer; HNPCC; copy number analysis; CGH; gene expression; Wnt; PIK3CA; CHEK2; gastric cancer; colorectal cancer;

    Sammanfattning : Esophageal cancer and colorectal cancer represents two major types of gastrointestinal tumors. Though refined surgery and introduction of novel chemotherapeutics have improved outcome, more than 2500 Swedes die from these diseases every year. Novel markers for early diagnosis, prognosis and treatment prediction are therefore needed. LÄS MER

  5. 4. Cell-autonomous and paracrine mechanisms underlying Pik3ca-driven vascular malformations

    Författare :Milena Petkova; Taija Mäkinen; Ebba Bråkenhielm; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PI3K; PI3KCA; lymphatic malformations; H1047R;

    Sammanfattning : Vascular malformation is a benign overgrowth of blood or lymphatic vessels leading to life-threatening consequences for affected patients. Activating mutations in the TIE2 receptor cause the majority of venous malformations (VMs), while somatic activating mutations in PIK3CA, leading to the overactivation of the PI3K-AKT pathway, cause both VMs and lymphatic malformations (LMs).

  7. 5. Alterations in the PI3K/AKT Signaling Pathway and Response to Adjuvant Treatment in Breast Cancer

    Författare :Gizeh Pérez-Tenorio; Olle Stål; Anne Lykkesfeldt; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Onkologi;

    Sammanfattning : (PI3K)/AKT signaling pathway could be a cause of therapeutic resistance in breast cancer. The PI3K/AKT pathway controls cell proliferation, cell growth and survival, and its members include oncogenes and tumor suppressor genes. Alterations in this pathway are frequent in cancer. LÄS MER
