    • HPV16 and HPV18 type-specific APOBEC3 and integration profiles in different diagnostic categories of cervical samples 

      Lagström, Sonja; Løvstad, Alexander H; Umu, Sinan Uğur; Ambur, Ole Herman; Nygård, Mari; Rounge, Trine Ballestad; Christiansen, Irene Kraus (Tumour Virus Research;Volume 12, December 2021, 200221, Peer reviewed; Journal article, 2021-07-14)
      Human papillomavirus (HPV) 16 and 18 are the most predominant types in cervical cancer. Only a small fraction of HPV infections progress to cancer, indicating that additional factors and genomic events contribute to the ...

    • HPV16 whole genome minority variants in persistent infections from young Dutch women 

      Lagström, Sonja; van der Weele, Pascal; Rounge, Trine Ballestad; Christiansen, Irene Kraus; King, Audrey; Ambur, Ole Herman (Journal of Clinical Virology;Volume 119, October 2019, Journal article; Peer reviewed, 2019-08-09)
      Background: Chronic infections by one of the oncogenic human papillomaviruses (HPVs) are responsible for near 5% of the global cancer burden and HPV16 is the type most often found in cancers. HPV genomes displayunexpected ...

    • Intra-host sequence variability in human papillomavirus 

      Mandishora, Racheal Shamiso Dube; Gjøtterud, Kristina Stormo; Lagström, Sonja; Stray-Pedersen, Babill; Duri, Kerina; Chin'ombe, Nyasha; Nygård, Mari; Christiansen, Irene Kraus; Ambur, Ole Herman; Chirenje, Mike Zvavahera; Rounge, Trine Ballestad (Papillomavirus Research. The Journal of HPV and other Small DNA Tumor Viruses;Volume 5, June 2018, Journal article; Peer reviewed, 2018-04-30)
      Human papillomaviruses (HPVs) co-evolve slowly with the human host and each HPV genotype displays epithelial tropisms. We assessed the evolution of intra HPV genotype variants within samples, and their association to ...

    • Self-collected and clinician-collected anal swabs show modest agreement for HPV genotyping 

      Mandishora, Racheal S. Dube; Rounge, Trine Ballestad; Fitzpatrick, Megan; Christiansen, Hanne Irene Kraus; Ambur, Ole Herman; Lagström, Sonja; Stray-Pedersen, Babill; Tommasino, Massimo; Palefsky, Joel; Chirenje, Zvavahera M. (PLOS ONE;16 (4): e0250426, Peer reviewed; Journal article, 2021-04-26)
      Background & aim: Women with HIV/HPV coinfection and cervical lesions are at increased risk of developing HPV related anal cancer. Self-collection of anal swabs may facilitate HPV molecular testing in anal cancer screening, ...

    • TaME-seq: An efficient sequencing approach for characterisation of HPV genomic variability and chromosomal integration 

      Lagström, Sonja; Umu, Sinan Uğur; Lepistö, Maija; Ellonen, Pekka; Meisal, Roger; Christiansen, Irene Kraus; Ambur, Ole Herman; Rounge, Trine Ballestad (Scientific Reports;9, Article number: 524 (2019), Journal article; Peer reviewed, 2018-11-26)
      HPV genomic variability and chromosomal integration are important in the HPV-induced carcinogenic process. To uncover these genomic events in an HPV infection, we have developed an innovative and cost-effective sequencing ...
