  2. 16. Gene regulation by chromatin remodelling complexes : SWI/SNF complex in mRNA processing and B-WICH complex in ribosomal gene expression

    Author : Antoni Gañez Zapater; Ann-Kristin Östlund-Farrants; Christopher W.J. Smith; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chromatin remodelling; SWI SNF; Brg1; Brm; alternative splicing; cleavage and polyadenylation; B-WICH; WSTF; ribosomal genes; Cell Biology; cellbiologi;

    Abstract : The aim of this project is to investigate the roles of chromatin remodelling complexes in gene regulation. It is focused on two groups of chromatin complexes: the mammalian BRG1 and BRM SWI/SNF complexes and the ISWI-containing B-WICH complex.Study 1 investigates the role of SWI/SNF complexes in alternative splicing.

  4. 17. Condensation of DNA for Gene Delivery: Studies on Vector-Nucleic Acid Interactions and Transfection Efficiency

    Author : Kristina Fant; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dendrimer; endocytosis; uptake; gene delivery; optical spectroscopy; structure-activity relationship; DNA; cell-penetrating peptide;

    Abstract : This thesis concerns the delivery of nucleic acids into cells and tissues with the aim to change or correct gene expression. The field of gene delivery has the ultimate goal of producing genetic drugs for clinical applications, and the activity in this area is intense although so far the use is limited to research purposes.

  5. 18. Applied bioinformatics for gene characterization

    Author : Raf M Podowski; Karolinska Institutet; Karolinska Institutet; []
    Keywords : bioinformatics; gene characterization; text mining; data visualization;

    Abstract : As the vast majority of human protein-encoding genes are now identified, the new challenge placed before life scientists is the determination of the functions of the proteins. Traditionally, intense, directed efforts are applied to decipher the function of a novel protein using laboratory techniques. READ MORE

  6. 19. GDNF gene delivery in an animal model of Parkinson's disease. Long-term effects on intact, injured and transplanted dopamine neurons using lentiviral gene transfer

    Author : Biljana Georgievska; Neurobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; Neurology; neuropsykologi; neurofysiologi; neurophysiology; transplantation; tyrosine hydroxylase; tetracycline; striatum; substantia nigra; sprouting; regulation; neuroprotection; lentivirus; gene therapy; GDNF; behavior; dopamine; neuropsychology;

    Abstract : Parkinson's disease is characterized by a progressive degeneration of dopaminergic neurons in the substantia nigra, leading to a loss of dopamine in the target structure striatum and development of motor symptoms, such as bradykinesia, rigidity and tremor. New experimental treatment strategies for Parkinson's disease are aimed at either preventing the degeneration of the dopaminergic neurons, or at restoring dopamine in the striatum by fetal dopaminergic transplants.

  7. 20. RhoGTPase Signaling in Cell Polarity and Gene Regulation

    Author : Ann-Sofi Johansson; Pontus Aspenström; Johan Lennartsson; Christer Larsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; RhoGTPase; Par6; cell polarity; aPKC; epithelial cell; PDGF; gene regulation; microarray; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

    Abstract : RhoGTPases are proteins working as molecular switches as they bind and hydrolyze GTP. They are in their active conformation when GTP is bound and are then able to interact with their effector proteins, which relay the downstream signaling. When the GTP is hydrolyzed to GDP, the RhoGTPase is inactivated. READ MORE
