  1. 11. Weighted Analysis of Microarray Experiments

    Författare :Anders Sjögren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA microarray; differential expression; gene expression; quality control QC ; quality assurance QA ; quality assessment; generalised linear model; empirical Bayes; weighted moderated statistic; invalid p-value; heteroscedasticity; WAME; heteroscedasticity;

    Sammanfattning : DNA microarrays are strikingly efficient tools for analysing gene expression for large sets of genes simultaneously. The aim is often to identify genes which are differentially expressed between some studied conditions, thereby gaining insight into which cellular mechanisms are differently active between the conditions.

  3. 12. Estrogen receptor alpha and beta in breast cancer - gene expression profiles and clinical implications

    Författare :Sofia Gruvberger; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk biologi; oncology; cancerology; Cytologi; onkologi; cancer; Cytology; artificial neural networks; gene expression profiling; microarray; tamoxifen; adjuvant endocrine therapy; ER; estrogen receptor beta; Breast cancer; estrogen receptor alpha; Clinical biology;

    Sammanfattning : Breast cancer is the most common malignancy in women in the Western world with about 10% of women developing breast cancer during their lifetime, of which one third will eventually succumb to the metastatic form of the disease. Breast cancer arises from the epithelial cells of the breast mammary gland, but the mechanisms involved in tumor initiation, progression, and metastasis are still not fully understood. LÄS MER

  4. 13. Molecular Characterization of Genomic Amplifications in Pancreatic Cancer

    Författare :Markus Heidenblad; Avdelningen för klinisk genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; FISH; Clinical genetics; PCR; cDNA microarray; array-based CGH; expression profiling; genomic profiling; Pancreatic cancer; gene amplification; Klinisk genetik;

    Sammanfattning : Pancreatic cancer includes multiple histologic subtypes that show large differences in their clinical and biological characteristics. Despite this diversity, more than 85% of the neoplasms in the organ are malignant ductal adenocarcinomas, which are the focus of the present thesis. LÄS MER

  5. 14. Epigenetic dysregulation in relation to psychiatric traits in adolescence and adulthood

    Författare :Adrian Desai Boström; Helgi B. Schiöth; Daniel Nätt; Uppsala universitet; []

    Sammanfattning : Epigenetics has evolved into a key research focus in the field of psychiatry. DNA methylation is the most researched epigenetic mechanism. In paper I-III, 130 and 93 adolescents were randomly recruited at two separate intervals. LÄS MER

  7. 15. Genetic Aspects of Endocrine Tumorigenesis : A Hunt for the Endocrine Neoplasia Gene

    Författare :Alberto Delgado Verdugo; Peyman Björklund; gunnar westin; Per Hellman; Filip Farnebo; Uppsala universitet; []

    Sammanfattning : Endocrine tumors arise from endocrine glands. Most endocrine tumors are benign but malignant variants exist. Several endocrine neoplasms display loss of parts of chromosome 11 or 18, produce hormones and responds poorly to conventional chemotherapeutics. The multiple endocrine neoplasia syndromes are mainly confined to endocrine tumors. LÄS MER
