  2. 1. Growth control mechanisms in normal and neoplastic mammalian cells

    Author : Mozhgan Afrakhte; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; PDGF-AA; TGF-beta; Inhibitory SMADs; Growth inhibition; CDK; CKI; Cdc25A; Genetik; Clinical genetics; Klinisk genetik; Genetics; genetik;

    Abstract : The main theme of the studies presented in this thesis is, the growth control mechanisms whose loss in normal cells predispose to or cause cancer. The balance between growth inhibitory and stimulatory mechanisms is crucial for the development and maintenance of a normal animal. READ MORE

  4. 2. The cell cycle regulators p18Ink4c and p19Ink4d : in vivo studies of their roles in tumorigenesis and development

    Author : Lisa Nilsson; Olle Heby; Martine Roussel; Klas Wiman; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi;

    Abstract : Progression through the G1, S, G2 and M phases of the cell cycle is controlled by cyclin-dependent kinases (Cdks) and cyclins. These proteins form active Cdk:cyclin complexes that phosphorylate specific substrates. READ MORE

  5. 3. Ras-MAPK signaling in differentiating SH-SY5Y human neuroblastoma cells

    Author : Anna-Karin Olsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Neuroblastoma; SH-SY5Y; differentiation; neurite; Ras; MAPK; PKC; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

    Abstract : Neuroblastoma is a malignant childhood cancer, originating from sympathetic neuroblasts of the peripheral nervous system. Neuroblastoma is a heterogenous group of tumours, while some are highly malignant others can spontaneosly mature into a more benign form or regress. READ MORE

  6. 4. Effects of interferon on cellular proliferation and apoptosis

    Author : Olle Sangfelt; Karolinska Institutet; Karolinska Institutet; []
    Keywords : interferon; malignancy; apoptosis; cell cycle;

    Abstract : Interferon (IFN) therapy is today a well-established treatment in many diseases, including various malignancies. How IFN exerts antitumor activity is not known, but several mechanisms have been suggested. READ MORE

  7. 5. Cyclins on the move : a time and a place for cyclin A2 and cyclin B1 in the human cell cycle

    Author : Helena Silva Cascales; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The ultimate aim of the cell cycle is to create an identical daughter cell. Therefore, correct progression through the different phases of the cell cycle is crucial to ensure faithful cell division. READ MORE
