  1. 1. Array-based Characterization of Chronic Lymphocytic Leukemia : - with Focus on Subsets Carrying Stereotyped B-cell Receptors

    Författare :Millaray Marincevic; Richard Rosenquist; Andreas Rosenwald; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chronic lymphocytic leukemia; array-based characterization; stereotyped B-cell receptors; subsets; antigens; SNP array; gene expression array; methylation array; Clinical genetics; Klinisk genetik; Clinical Genetics; Klinisk genetik;

    Sammanfattning : In chronic lymphocytic leukemia (CLL), the presence of multiple subsets expressing ‘stereotyped’ B-cell receptors (BCRs) has implicated antigen(s) in leukemogenesis. These stereotyped subsets display similar immunoglobulin (IG) gene usage, almost identical complementarity determining region 3’s and may share clinical features. LÄS MER

  3. 2. DNA methylation in the placenta and in cancerwith special reference to folate transporting genes

    Författare :Sanja Farkas; Torbjörn Nilsson; Lars Breimer; Warren D. Kruger; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; DNA methylation; CRC; placenta; cervix; leukocytes; T-DMRs; folate; array; expression; Biomedicin; Biomedicine;

    Sammanfattning : DNA methylation is an epigenetic mechanism that regulates the gene transcription. Folate is used in cellular synthesis of methyl groups, nucleic acids and amino acids. In complex diseases like cancer and neural tube defects (NTD), various genetic and epigenetic alterations can be found that disrupt the normal cell function. LÄS MER

  4. 3. Application of Genomic and Expression Arrays for Identification of new Cancer Genes

    Författare :Helena Nord; Teresita Díaz de Ståhl; Jan Dumanski; Susan Pfeifer; Blomquist Erik; Segersten Ulrika; David Gisselsson Nord; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Array-CGH; Expression array; Copy number variation; Glioblastoma; Medulloblastoma; Bladder carcinoma; Oncogenes; Tumor suppressor genes; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; Medical genetics; Medicinsk genetik; Tumour biology; Tumörbiologi; Genetics; Genetik; Medical Genetics; Medicinsk genetik;

    Sammanfattning : Copy number variation (CNV) comprises a recently discovered kind of variation involving deletion and duplication of DNA segments of variable size, ranging from a few hundred basepairs to several million. By altering gene dosage levels or disrupting proximal or distant regulatory elements CNVs create human diversity. LÄS MER

  5. 4. Antenna array mapping for DOA estimation in radio signal reconnaissance

    Författare :Per Hyberg; Björn Ottersten; Alex Gershman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Array mapping; array interpolation; Signalbehandling; Signal processing; Signalbehandling;

    Sammanfattning : To counter radio signal reconnaissance, an efficient way of covert communication is to use subsecond duration burst transmissions in the congested HF band. Against this background, the present thesis treats fast direction finding (DF) using antenna arrays with known response only in a few calibration directions. LÄS MER

  7. 5. 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.
