  1. 1. Regulation of adenovirus alternative pre-mRNA splicing : Functional characterization of exonic and intronic splicing enhancer elements

    Author : Bai-Gong Yue; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; adenovirus; pre-mRNA splicing; splicing enhancer; MLTU; L1; SR protein; ASF SF2; E. coli; phosphorylation; dephosphorylation; Biokemi; Biochemistry; Biokemi; mikrobiologi; Microbiology;

    Abstract : Pre-mRNA splicing and alternative pre-mRNA splicing are key regulatory steps controlling geneexpression in higher eukaryotes. The work in this thesis was focused on a characterization of thesignificance of exonic and intronic splicing enhancer elements for pre-mRNA splicing. READ MORE

  2. 2. Control of human papillomavirus type 1 late mRNA stability and translation by an AU-rich RNA element

    Author : Marcus Sokolowski; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; HPV-1; HPV-16; late genes; 3´ UTR; L1; L2; c-fos; AU rich element; HuR; hnRNP C1 C2; mRNA stability; translation; Biokemi; Biochemistry; Biokemi; Medical Virology; medicinsk virologi;

    Abstract : Human Papillomaviruses (HPVs) infect the epithelial tissues in humans and infection with certain high-risk types is associated with cancer. The expressionof the HPV late capsid genes is dependent on cell differentiation. This may be one reason for the lack of HPV replication in vitro. READ MORE

  3. 3. Viral Strategies to Regulate Transcription and Pre-mRNA Splicing

    Author : Shaoan Fan; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Adenovirus E1B-55kDa; E4-ORF4; E4-ORF6 proteins; L1 mRNA; Polyoma virus small T antigen; regulation; transcription; splicing; PP2A; Biokemi; Biochemistry; Biokemi; Medical Virology; medicinsk virologi;

    Abstract : A typical DNA virus encodes for a few key regulatory proteins that modify the host cell biosynthetic machinery to achieve a selective viral gene statement. One such example is illustrated by the adenovirus E4-ORF4 protein, which form an enzymatically active complex with the serine and threonine-specific protein phosphatase 2A (PP2A). READ MORE

  4. 4. Protein-RNA interplay in translation. Structural studies of RRF, SelB and L1

    Author : Maria Selmer; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biophysics; Molekylär biofysik; crystallography; mimicry; translation factor; L1; SelB; protein synthesis; RRF;

    Abstract : Translation is a central biological process, that is catalysed by a machinery consisting of RNA and protein. In this thesis three different protein components of the bacterial protein synthesis system have been structurally studied. READ MORE

  5. 5. Regulation of Human Papillomavirus Type 16 Early and Late Gene Expression

    Author : Haoran Yu; Avdelningen för medicinsk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HPV16; mRNA; Splicing; gene expression;

    Abstract : Human papillomavirus type 16 (HPV16) is a cancer-causing virus that contributes to at least 70% of cervical cancer as well as to other anogenital cancers and head and neck cancer. Understanding HPV16 gene regulation is important to enhance our understanding of HPV16 infections and may contribute to development of antiviral drugs. READ MORE
