  1. 21. Array-based Genomic and Epigenomic Studies in Healthy Individuals and Endocrine Tumours

    Författare :Johanna Sandgren; Gunnar Westin; Teresita Diaz de Ståhl; Göran Åkerström; Ola Hessman; Winand Dinjens; Uppsala universitet; []
    Nyckelord :genome; copy number variants; cancer; Pheochromocytoma; epigenome; array-CGH; ChIP-chip; gene expression; tumour suppressor genes; oncogenes; MEDICINE; MEDICIN; Kirurgi; Surgery;

    Sammanfattning : The human genome is a dynamic structure, recently recognized to present with significant large-scale structural variation. DNA-copy number changes represent one common type of such variation and is found both between individuals and within the somatic cells of the same individual, especially in disease states like cancer.

  3. 22. Vitamin D Hydroxylating Enzymes and Analogues in Parathyroid Tumors and Breast Cancer

    Författare :Ulrika Segersten; Gunnar Westin; Per Hellman; Göran Åkerström; Martin Bäckdahl; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; hyperparathyroidism; breast cancer; vitamin D; CYP27B1; CYP24A1; vitamin D analogues; ketoconazole; vitamin D receptor; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Sammanfattning : In hyperparathyroidism (HPT) raised serum concentrations of ionized calcium is caused by increased secretion of parathyroid hormone (PTH) by parathyroid tumors. Active vitamin D, 1α,25-dihydroxyvitamin D3, is known to suppress PTH secretion and to reduce proliferation of parathyroid tumor cells. LÄS MER

  4. 23. Green Chemical Synthesis of II-VI Semiconductor Quantum Dots

    Författare :Robina Shahid; Mamoun Muhammed; Gunnar Westin; KTH; []
    Nyckelord :Semiconductor; Quantum Dots; Microwave; Ionic Liquids; Green Chemical Syntheis; Quantum Confinement; Optical Properties;

    Sammanfattning : Nanotechnology is the science and technology of manipulating materials at atomic and molecular scale with properties different from bulk. Semiconductor QDs are important class of nanomaterials with unique physical and chemical properties owing to the quantum confinement effect. LÄS MER

  5. 24. Wnt/β-catenin Signaling and Epigenetic Deregulation in Breast Cancer and Parathyroid Tumours

    Författare :Jessica Svedlund; Gunnar Westin; Göran Åkerström; Peyman Björklund; Ola Nilsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wnt signaling; parathyroid; epigenetic; Medicin; Medicine; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Sammanfattning : The Wnt/β-catenin signaling pathway is often deregulated in cancer. Here we investigate Wnt/β-catenin signaling, aberrant accumulation of β-catenin, and epigenetic deregulation in breast cancer and parathyroid tumours. LÄS MER
