  1. 6. Immunofluorescence studies on the cell cycle expression of cyclin A and cyclin E

    Författare :Fredrik Erlandsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cell cycle regulation; cyclin A; cyclin E; immunofluorescence staining;

    Sammanfattning : Cell cycle progression is tightly regulated in normal eucaryotic cells. Cancer is caused by the transformation of cells, and is always associated with defects in the cell cycle regulatory machinery. LÄS MER

    Sammanfattning : ABSTRACTCell cycle regulation in human renal cell carcinomaYlva Hedberg, Departments of Medical Biosciences, Pathology, and Surgical andPerioperative Sciences, Urology Andrology, Umeå University, SwedenDeregulated growth control is a hallmark of neoplasia potentially caused by aberrant expression of cell cycle regulatory proteins. The importance of such aberrations in human renal cell carcinoma (RCC) has not been fully clarified. LÄS MER

  4. 8. The Prognostic and Treatment Predictive Value of Proliferation and TIMP-1 in Breast Cancer

    Författare :Marie Klintman; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast cancer; predictive marker; resistance; prognostic factor; proliferation; prospective; TIMP-1; Ki67; S-phase; MAI; PPH3; cyclin B1; cyclin A; node-negative; validation;

    Sammanfattning : Breast cancer is the most common tumour form and the second leading cause of death in solid tumours in women in the Western world. Despite improvements in the treatment, a considerable number of patients will relapse and die from their breast cancer. LÄS MER

  5. 9. Functional studies in yeast of cyclin C and the RNA polymerase II Mediator complex

    Författare :Darius Balciunas; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Cyclin C; RNA polymerase II; Mediator; glucose repression; RAS cAMP pathway; Saccharomyces cerevisiae; Biokemi; Biochemistry; Biokemi; Medical Biochemistry; medicinsk biokemi;

    Sammanfattning : Cyclin C belongs to a group of cyclins that are not cell cycle-regulated. It was first cloned from Drosophila and rat, but its role was not understood until the yeast cyclin C homologue Srb 11 was identified in several genetic screens for transcriptional repressors and subsequently was shown to be associated with the RNA polymerase II Mediator complex.

  7. 10. G1-phase cyclin expression in neoplastic B cells

    Författare :Richard Scuderi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cell cycle; G1 phase; cyclin D; cyclin E; EBV; Burkitt s; B-ALL; B-CLL; apoptosis;

    Sammanfattning : By virtue of the role of G1-phase cyclin proteins as regulators of differentiation, proliferation, and apoptosis, their improper expression can lead to altered cellular homeostasis and tumor formation. Cyclins provide the regulatory partner for cyclin-cdk complexes whose enzymatic activity drives cell cycle progression. LÄS MER
