Costanzi, Jean-Marc; Stosic, Milan; Løvestad, Alexander; Ambur, Ole Herman; Rounge, Trine Ballestad; Christiansen, Irene Kraus (Peer reviewed; Journal article, 2024)Human papillomavirus type 16 (HPV16) is the most common cause of cervical cancer, but most infections are transient with lesions not progressing to cancer. There is a lack of specific biomarkers for early cancer risk ... -

Here we compare HPV genotyping by Next ... -
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 ... -
