  1. 6. In Vitro Studies of Adrenocorticolytic DDT Metabolites, with Special Focus on 3-methylsulfonyl-DDE

    Författare :Vendela Asp; Ingvar Brandt; Ulrika Bergström; Olle Söder; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toxicity; 3-methylsulfonyl-DDE; CYP; adrenal cortex; metabolic activation; steroid hormones; Y-1; H295R; mitotane; adrenocortical carcinoma; Toxicology; Toxikologi; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

    Sammanfattning : The DDT metabolite 3-methylsulfonyl-DDE (3-MeSO2-DDE) is bioactivated by cytochrome P450 11B1 (CYP11B1) in the adrenal cortex of mice and forms irreversibly bound protein adducts, reduces glucocorticoid secretion, and induces cell death selectively in cortisol-producing adrenocortical cells. 3-MeSO2-DDE has therefore been proposed as a lead compound for an improved adrenocortical carcinoma (ACC) therapy.

  3. 7. Genetic factors in childhood cancer. Associations between tumors in childhood and adulthood, and prevalence of germline TP53 mutations

    Författare :Susanne Magnusson; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Childhood cancer; hereditary factors; breast cancer; survival; hereditary breast and ovarian cancer; hereditary non-polyposis colorectal cancer; familial malignant melanoma; BRCA1; BRCA2; mismatch repair; CDKN2A; familial risk; multiple childhood tumors; Li-Fraumeni syndrome; TP53; adrenocortical carcinoma; choroid plexus tumors; rhabdomyosarcoma;

    Sammanfattning : The etiology of childhood cancer is largely unknown. Approximately 1-10% of all childhood tumors are associated with known cancer predisposition syndromes. However, the contribution may be underestimated due to the failure to detect patients with genetic susceptibility for cancer when relying on known family pattern and anomalies. LÄS MER

  4. 8. Centrosome aberrations and tumor development

    Författare :Kaoru Fujioka; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Centrosome; cervical carcinoma; adrenocortical tumor; tetraploidization; p53; griseofulvin; 13-cis-retinoic acid.;

    Sammanfattning : The transformation of a normal cell to a tumor cell is a result of a failure somewhere in a complicated system of coordination, checkpoints and control mechanisms of inhibitors and activators working as triggers and transactivators of genes of importance for cell cycle progression. In the present thesis, the focus is on an important function that controls the segregation of the chromosomes during cell division to the next generation of two daughter cells. LÄS MER

  5. 9. Differential microRNA and metabolic expressions in neuroendocrine and cervical carcinomas

    Författare :Patrick Scicluna; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : MicroRNAs (miRNAs) are important regulators of many biological processes involved in cancer development and progression. However, the functional roles of miRNAs in some cancer types are still poorly understood. LÄS MER

  7. 10. Clinical and functional aspects of microRNA regulation in human cancers

    Författare :Stefano Caramuta; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : miRNAs are short single-stranded non-coding RNAs which regulate gene expression at the post-transcriptional level in many biological processes, including proliferation, apoptosis and differentiation. A number of studies have shown the importance of miRNAs in carcinogenesis and accumulating evidence supports their role as diagnostic and prognostic biomarkers in human cancers. LÄS MER
