  1. 1. Regulation of Human Papillomavirus Type 16 mRNA Splicing and Polyadenylation

    University dissertation from Uppsala : Institutionen för medicinsk biokemi och mikrobiologi

    Author : Xiaomin Zhao; Uppsala universitet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical sciences; human papillomavirus type 16; gene regulation; splicing; polyadenylation; 3 UTR; MEDICIN OCH VÅRD; MEDICINE; MEDICIN;

    Abstract : Human papillomavirus type 16 (HPV-16) is the major causative agent of cervical cancer. The life cycle of this oncogenic DNA tumour virus is strictly associated with the differentiation program of the infected epithelial cells. Expression of the viral capsid genes L1 and L2 can only be detected in the terminally differentiated epithelial cells. READ MORE

  2. 2. The Role of Polyadenylation in Human Papillomavirus Type 16 Late Gene Expression

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Daniel Öberg; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; HPV-16; polyadenylation; mRNA stability; codon usage; hnRNP H; DSE; splicing; negative element; RNA processing; Molekylärbiologi; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi;

    Abstract : High-risk type human papillomaviruses (HPVs) are associated with cancer. HPVs are strictly epitheliotropic and infect basal cell layers, establishing a life cycle strongly linked to the differentiation stage of the infected cells. The viral capsid late genes, L2 and L1, are only expressed in terminally differentiated epithelium. READ MORE

  3. 3. Regulation of RNA Processing in Human Papillomavirus Type 16

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Margaret Rush; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; RNA processing; human papillomavirus; HPV-16; alternative splicing; polyadenylation; exonic splicing enhancer; 3 UTR; upstream polyadenylation element; SR proteins; Molekylärbiologi; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi;

    Abstract : Human papillomavirus type 16 (HPV-16) is the major cause of cervical cancer. HPV-16 gene expression is tightly linked to the differentiation programme of the infected epithelium. Expression of the late genes, L1 and L2, encoding the capsid proteins, is delayed until the more terminally differentiated cells. READ MORE

  4. 4. Functional aspects on the Epstein-Barr virus nuclear antigen 5

    University dissertation from Göteborg

    Author : Martin Dufva; Göteborgs universitet.; Gothenburg University.; [2001]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Epstein-Barr Virus; EBV; B-cell; transformation; cDNA array; polyadenylation; transcription; cell cycle; apoptosis; two-hybrid system.;

    Abstract : The Epstein-Barr virus (EBV) infects resting B-cells. This leads to an EBV driven transformation of the resting B-cell into a cell with an activated B-cell phenotype that proliferates indefinitely in vitro. Epstein-Barr Nuclear antigen 5 (EBNA5) is one out of six EBV encoded protein involved in transformation of resting B-cell. READ MORE

  5. 5. Regulation of Mammalian Poly(A) Polymerase Activity

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ann-Charlotte Thuresson; Uppsala universitet.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicine; poly A polymerase; PAP; polyadenylation; isoforms; phosphorylation; alternative splicing; CPSF interaction; aminoglycosides; Biomedicin; MEDICINE Microbiology; immunology; infectious diseases Microbiology; MEDICIN Mikrobiologi; immunologi; infektionssjukdomar Mikrobiologi; Molekylär cellbiologi; Molecular Cellbiology;

    Abstract : Poly(A) polymerase (PAP) is the enzyme catalyzing the synthesis of the adenine tail to the 3’-end of mRNA. This A-tail is present on the majority of the primary RNA transcripts of protein-coding genes, and is important for mRNA stability, export to the cytoplasm and translation. Therefore, PAP is a key regulator of eukaryotic gene expression. READ MORE
