    Abstract Persistent infection with oncogenic human papillomaviruses (HPVs) is necessary for the development of cervical cancer, although the accumulation of somatic mutations in the host genome is also required for the generation of invasive cervical cancer. Recent studies have demonstrated concomitant genetic changes in the HPV genome; however, their relevance to cervical carcinogenesis is poorly understood. Here we review our recent study investigating the within-host genetic diversity of HPV and its relationship with cervical cancer progression through deep sequencing analyses of viral whole-genome sequences in clinical specimens. Intriguingly, HPV genomes within individual clinical samples show an astonishingly high level of nucleotide variation across all histological grades of cervical lesions. Among the various substitution patterns, C-to-T and C-to-A substitutions are the predominant changes observed in the HPV genomes. Analysis of the trinucleotide context for substituted bases reveals that TpCpN (N is any nucleotide), which is a preferred target sequence for the cellular apolipoprotein B mRNA-editing enzyme, catalytic polypeptide-like (APOBEC) proteins, is the major target for C-to-T substitutions in the HPV genomes. These mutational signature analyses strongly imply that within-host HPV variations are mostly generated through APOBEC-mediated mutagenesis. Because the HPV oncogenes E6 and E7 harbor APOBEC-related mutations, we propose a potential role for APOBEC-mediated mutagenesis in cervical carcinogenesis.

    Abstract Approximately 500,000 women are diagnosed with cervical cancer annually, with high-grade cervical intraepithelial neoplasia (CIN) estimated to be 20 times higher. The diathermy ablation is an inexpensive minimally invasive surgeries for CIN. However, little is known about the treatment outcomes. A prospective clinical trial was therefore conducted to evaluate ablation outcomes based on detailed colposcopy findings, cytology, and biopsy results over a two-year period. We enrolled CIN2 (n = 32) and CIN3 (n = 7) patients. Eligibility criteria included: aged between 29 and 49 (median: 36, mean: 36.3), visible transformation zone with high-grade lesions not entirely occupying the cervix, and histologically diagnosed with CIN2 or CIN3. Cytology and HPV genotyping were performed, and colposcopic findings were evaluated. Colposcopy-guided diathermy ablation was conducted by a certified gynecologic oncologist. The incidence of recurrent or residual disease was 5.1% (2/39, 95% confidence interval: - 0.02 to 0.12). The prevalence of HPV infection at 12 months decreased after surgery, as 67.6% (23/34, 0.52-0.83) of patients were HPV-negative. No severe adverse events were reported, while there were five pregnancies with full-term deliveries. The promising outcome was possibly due to selection of rigorous surgical indication and skilled surgical techniques. The study highlights the importance of experienced and skilled colposcopists.TrialRegistry This study was registered in the clinical trial registration system of the University hospital Medical Information Network Clinical Trials Registry (UMIN-CTR ID: UMIN000024483). Open for the trial to the public through the website: 01/11/2016. First registration of the patient: 30/01/2017.

    Abstract Human papillomavirus (HPV) infects epithelial basal cells in the mucosa and either proliferates with the differentiation of the basal cells or persists in them. Multiple host factors are required to support the HPV life cycle; however, the molecular mechanisms involved in cell entry are not yet fully understood. In this study, we performed a genome-wide clustered regularly interspaced short palindromic repeat (CRISPR)-CRISPR-associated protein 9 (Cas9) knockout (KO) screen in HeLa cells and identified folliculin (FLCN), a GTPase-activating protein for Rag GTPases, as an important host factor for HPV infection.

    Abstract Human papillomavirus type 31 (HPV31) is detected less frequently in cervical cancer than two major causative types, HPV16 and HPV18. Here, we report a comprehensive analysis of HPV31 genome sequences in cervical lesions collected from Japanese women. Of 52 HPV31-positive cervical specimens analyzed by deep sequencing, 43 samples yielded complete genome sequences of around 7900 base pairs and 9 samples yielded partially deleted genome sequences. Phylogenetic analysis showed that HPV31 variant distribution was lineage A in 19 samples (36.5%), lineage B in 28 samples (53.8%), and lineage C in 5 samples (9.6%), indicating that lineage B variants are dominant among HPV31 infections in Japan. Deletions in the viral genome were found in the region from the

    Abstract Human papillomavirus (HPV) is a sexually transmitted virus with an approximately 8-kilo base DNA genome, which establishes long-term persistent infection in anogenital tissues. High levels of genetic variations, including viral genotypes and intra-type variants, have been described for HPV genomes, together with geographical differences in the distribution of genotypes and variants. Here, by employing a maximum likelihood method, we performed phylogenetic analyses of the complete genome sequences of HPV16, HPV18 and HPV58 available from GenBank (n = 627, 146 and 157, respectively). We found several characteristic clusters that exclusively contain HPV genomes from Japan: two for HPV16 (sublineages A4 and A5), one for HPV18 (sublineage A1) and two for HPV58 (sublineages A1 and A2). Bayesian phylogenetic analyses of concatenated viral gene sequences showed that divergence of the most recent common ancestor of these Japan-specific clades was estimated to have occurred ~98,000 years before present (YBP) for HPV16 A4, ~39,000 YBP for HPV16 A5, ~38,000 YBP for HPV18 A1, ~26,000 for HPV58 A1 and ~25,000 YBP for HPV58 A2. This estimated timeframe for the divergence of the Japan-specific clades suggests that the introduction of these HPV variants into the Japanese archipelago dates back to at least ~25,000 YBP and provides a scenario of virus co-migration with ancestral Japanese populations from continental Asia during the Upper Paleolithic period.

    Abstract The TEAD family of transcription factors requires associating cofactors to induce gene expression. TEAD1 is known to activate the early promoter of human papillomavirus (HPV), but the precise mechanisms of TEAD1-mediated transactivation of the HPV promoter, including its relevant cofactors, remain unexplored. Here, we reveal that VGLL1, a TEAD-interacting cofactor, contributes to HPV early gene expression. Knockdown of VGLL1 and/or TEAD1 led to a decrease in viral early gene expression in human cervical keratinocytes and cervical cancer cell lines. We identified 11 TEAD1 target sites in the HPV16 long control region (LCR) by

    Abstract Human papillomavirus (HPV) infects the basal cells of epithelia and maintains its genome stably as episomes. However, the mechanisms of viral genome maintenance are not fully understood. Here, using normal human immortalized keratinocytes (NIKS), we identified the homeobox transcription factor HOXC13 as a critical host factor for retaining the copy number of HPV genomes in the cell. HOXC13 knockdown in NIKS significantly decreased mRNA levels of the E1 gene, which encodes a DNA helicase required for HPV genome replication, accompanied by a reduction of the viral genome copy number. Chromatin immunoprecipitation assays revealed HOXC13 binding to the long control region that regulates E1 expression. These results indicate that HOXC13 plays invaluable roles in maintaining HPV persistent infection through E1 gene upregulation.
