  1. 1. Functional characterization of the human adenovirus pVII protein and non-coding VA RNAI

    Författare :Raviteja Inturi; Tanel Punga; Goran Akusjarvi; Thomas Dobner; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adenovirus; VA RNA; protein VII; Ubiquitination; proteasome; anti-viral; Medical Biochemistry; Medicinsk biokemi; Mikrobiologi; Microbiology; Medical Virology; Medicinsk virologi;

    Sammanfattning : Human adenovirus (HAdV) is a common pathogen causing a broad spectrum of diseases. HAdV encodes the pVII protein, which is involved in nuclear delivery, protection and expression of viral DNA. To suppress the cellular interferon (IFN) and RNA interference (RNAi) systems, HAdVs encode non-coding virus-associated (VA) RNAs. LÄS MER

    Sammanfattning : Adenovirus serotype 5 (Ad5) is widely used as an oncolytic agent for cancer therapy. However, its infectivity is highly dependent on the expression level of coxsackievirus-adenovirus receptor (CAR) on the surface of tumor cells. LÄS MER

  3. 3. Posttranscriptional Regulation of Human Papillomavirus Type 16 Late mRNAs

    Författare :Brian Collier; Carl Baker; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; HPV 16; Negative Element; Translation; mRNA stability; Codon Usage; RNA binding proteins; Biokemi; Biochemistry; Biokemi; Medical Virology; medicinsk virologi;

    Sammanfattning : The lifecycle of the human papillomavirus (HPV) is strictly linked to the programmed differentiation of the host cell it infects. Production of late proteins, which are used for the production of the major and minor capsid proteins, is only seen upon terminal differentiation of the epithelium. LÄS MER

  4. 4. Viral Control of SR Protein Activity

    Författare :Camilla Estmer Nilsson; Neus Visa; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; adenovirus; ASF SF2; dephosphorylation; E4-ORF4; L1; MLTU; PP2A; splicing; SR proteins; vaccinia virus; Biokemi; Biochemistry; Biokemi; Medical Virology; medicinsk virologi;

    Sammanfattning : Viruses modulate biosynthetic machineries of the host cell for a rapid and efficient virus replication. One important way of modulating protein activity in eukaryotic cells is by reversible phosphorylation. In this thesis we have studied adenovirus and vaccinia virus, two DNA viruses with different replication stategies. LÄS MER

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

    Författare :Shaoan Fan; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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). LÄS MER
