In this study, we show that the lncRNA DINO is a driver of HPV DNA replication. DINO levels increase during keratinocyte differentiation and ectopic expression of DINO promotes both HPV genome replication and the formation of replication foci, and this is independent of keratinocyte differentiation signals. Ectopic DINO expression increases select early viral transcript levels including E1^E4, E1, and E2. Notably, DINO\u2019s subcellular localization is also context-dependent: during DNA damage DINO is predominantly cytoplasmic, but during keratinocyte differentiation nuclear retention is observed. This differential localization suggests that DINO has distinct functional roles in keratinocyte differentiation and HPV biology. Our findings highlight DINO as a lncRNA that promotes HPV genome replication and suggest that lncRNAs may play underappreciated roles in host-virus interactions. This work provides a foundation for further exploration of lncRNAs as potential therapeutic targets in HPV-associated diseases.<\/jats:p>\n                <jats:sec>\n                  <jats:title>Importance<\/jats:title>\n                  <jats:p>Human papillomaviruses (HPVs) are the causative agents of many anogenital tract and oral cancers, yet the host factors that trigger and support viral genome replication during the productive life cycle are incompletely understood. This study identifies the long noncoding RNA DINO as a host regulator that promotes HPV DNA replication, replication focus formation, and early viral gene expression independently of keratinocyte differentiation. We further show that DINO exhibits context-dependent subcellular localization, suggesting distinct functional roles in cellular stress responses and HPV biology. These findings reveal an underappreciated role for host lncRNAs in virus\u2013host interactions and provide new insight into cellular pathways that support HPV genome replication.<\/jats:p>\n                <\/jats:sec>","DOI":"10.64898\/2026.06.19.733329","type":"posted-content","created":{"date-parts":[[2026,6,20]],"date-time":"2026-06-20T05:20:23Z","timestamp":1781932823000},"source":"Crossref","is-referenced-by-count":0,"title":["Differentiation-independent Activation of HPV Genome Replication by the lncRNA DINO"],"prefix":"10.64898","author":[{"given":"Warda","family":"Arman","sequence":"first","affiliation":[{"name":"Molecular Microbiology Program; Graduate School of Biomedical Sciences, Tufts University"},{"name":"Department of Developmental Molecular and Chemical Biology, Tufts University School of Medicine, Boston, MA 02115, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alison A.","family":"McBride","sequence":"additional","affiliation":[{"name":"Laboratory of Viral Diseases, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, Maryland, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3288-9935","authenticated-orcid":false,"given":"Karl","family":"Munger","sequence":"additional","affiliation":[{"name":"Molecular Microbiology Program; Graduate School of Biomedical Sciences, Tufts University"},{"name":"Department of Developmental Molecular and Chemical Biology, Tufts University School of Medicine, Boston, MA 02115, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"54368","reference":[{"key":"2026062217201993000_2026.06.19.733329v1.1","doi-asserted-by":"crossref","unstructured":"Milano G , Guarducci G , Nante N , Montomoli E , Manini I .
