  1. 1. 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

  2. 2. Human Papilloma Virus, Epstein-Barr Virus, and Herpes Simplex Virus Type-1 in Oral Squamous Cell Carcinomas from Three Populations

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jamshid Jalouli; Uppsala universitet.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HPV; EBV; HSV; Oral Squamous Cell Carcinoma; Leukoplakia; Oral Lichen Planus; Oral Submucuos Fibrosis; Toombak; Betel quid; Snuff; MEDICINE Surgery Oncology; MEDICIN Kirurgi Onkologi; Oncology; Onkologi;

    Abstract : Most oral squamous cell carcinoma (OSCC) is believed to develop via a multistep process of cumulative gene damage in epithelial cells. Increasing incidence of OSCC and evidence that traditional risk factors may not be responsible directed us to investigate the prevalence of virus in pre- and malignant samples. READ MORE

  3. 3. Oral cancer with special reference to virus detection and quantitative gene expression

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Miranda Shojaeian Jalouli; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HPV; EBV; HSV-1; Oral Squamous Cell Carcinoma; Leukoplakia; apopto-sis; cell cycle regulation; intermediate filament proteins.; Medicinsk genetik; Medical Genetics;

    Abstract : Background. Head and neck cancers (HNC) are among the most common malignancies worldwide, and about 90–92% of oral neoplasias are oral squamous cell carcinomas (OSCC). Alcohol and tobacco consumption have been recognized as the main risk factors for OSCC development. READ MORE

  4. 4. Epstein-Barr virus and genomic instability - a new look at the mechanisms of viral oncogenesis

    University dissertation from Stockholm : Karolinska Institutet, Dept of Cell and Molecular Biology

    Author : Siamak Akbari Kamranvar; Karolinska Institutet.; Karolinska Institutet.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; EBV;

    Abstract : EBV is associated with a variety of lymphoid and epithelial malignancies but the mechanisms of oncogenesis are still not fully understood. The aim of the work described in this thesis was to assess whether induction of genomic instability, as defined by the accumulation of non-clonal genetic aberrations, could play a role in EBV oncogenesis and identify the viral protein(s) responsible for this phenotype.

  5. 5. Regulation and expression of Epstein-Barr virus nuclear antigen 1 in transplant patients and cell culture

    University dissertation from Stockholm : Karolinska Institutet, Dept of Cell and Molecular Biology

    Author : Malin Berggren; Göteborgs universitet.; Gothenburg University.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; EBV;

    Abstract : Epstein-Barr virus (EBV) is a human herpes virus that infects over 90% of the world population. Once infection has occurred, the virus persists for life in its host, mainly in an asymptomatic, latent stage with only a few active viral genes. READ MORE
