Background: Human papillomavirus (HPV) vaccine was recommended in 2006 for routine vaccination of US females aged 11-12 years. Most vaccine used through 2014 was quadrivalent vaccine (4vHPV), which prevents HPV-6, -11, -16, and -18 infection. To evaluate vaccine impact, we measured HPV prevalence in the National Health and Nutrition Examination Survey (NHANES). Methods: We analyzed HPV DNA types detected in self-collected cervicovaginal specimens and demographic, sexual behavior, and self-reported vaccination data from females 14-34 years old...

High-risk human papillomaviruses (HPVs) are oncogenic DNA viruses that promote carcinogenic signaling by their oncoproteins mainly E6 and E7. A well-defined promoter regulates expression and enhancer region on HPV genome containing number of cis elements that essentially require a set of cognate host transcription factors to regulate viral promoter gene activity. Expression of these host factors is tightly regulated at multiple levels such as transcriptional, post-transcriptional and post-translational level...

Cervical cancer is primarily caused by Human papillomavirus (HPV) infection, but other factors such as smoking habits, co-infections and genetic background, can also contribute to its development. Although this cancer is avoidable, it is the fourth most frequent type of cancer in females worldwide and can only be treated with chemotherapy and radical surgery. There is a need for biomarkers that will enable early diagnosis and targeted therapy for this type of cancer. Therefore, a systems biology pipeline was applied in order to identify potential biomarkers for cervical cancer, which show significant reports in three molecular aspects: DNA sequence variants, DNA methylation pattern and alterations in mRNA/protein expression levels...

Squamous cell carcinoma of the head and neck (SCCHN) comprises a large group of cancers in the oral cavity and nasopharyngeal area that typically arise in older males in association with alcohol/tobacco usage. Within the oral cavity, the mobile tongue is the most common site for tumour development. The incidence of tongue squamous cell carcinoma (TSCC) is increasing in younger people, which has been suggested to associate with a viral aetiology. Two common human oncogenic viruses, human papilloma virus (HPV) and Epstein-Barr virus (EBV) are known causes of certain types of SCCHN, namely the oropharynx and nasopharynx, respectively...

Cervical cancer is the second most common cancer in women worldwide. Human papillomavirus (HPV) is considered as the main cause of invasive cervical cancer and cervical intra-epithelial neoplasia. High risk HPV DNA has been shown to be present in 99.7% of cervical cancers. So HPV DNA testing for screening of cervical cancers may play a potential role in early detection and management of cervical cancer. With above background a cross sectional study was undertaken to estimate the prevalence and to identify the associated risk factors of human Papillomavirus infection among Visual Inspection with Acetic acid (VIA) positive women attending at colposcopy clinic of Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from July 2013 to December 2014...

BACKGROUND: Vaccines based on virus-like particles are effective against Human Papilloma Virus (HPV) infection; however, they have not shown a therapeutic effect against HPV-associated diseases. New immunotherapy strategies based on immune responses against tumor antigens can positively affect the clearance of HPV-associated lesions. OBJECTIVE: To generate two therapeutic fusion DNA vaccines (optimizedE7/mouseHSP70 and wildE7/mouseHSP70) to induce antitumor specific responses in mice models...

Since the introduction of Pap smear screening, the incidence and mortality of cervical cancer (CC) have been reduced drastically in USA and in other western states. Nevertheless, CC still remains the main cause of death from gynecological cancer in developing countries where screening programs are scant or inexistent. This evidence highlights the efficacy of screening, and the wide use of Human Papilloma Viruses (HPV) vaccines in developed countries. More and more people are, consequentially, undergoing a screening procedure, usually combined with HPV DNA test, increasing the early diagnosis of intraepithelial HPV-related lesions...

The purpose of this study was to investigate the distribution of Chlamydia trachomatis (CT) genotypes in infective diseases of the female lower genital tract, especially in cervical diseases. This study included 128 CT-positive women. DNA was extracted from cervical swabs. Omp1 gene PCR-RFLP and sequencing were used to confirm the subtypes of CT. The association of subtypes with age, clinical symptoms, cervical cytology, and biopsy results was further analyzed. Omp1 gene PCR-RFLP and sequencing showed that the order of prevalent CT genotypes in the female lower genital tract was D (n=38, 29...

The identification of some types of human papillomavirus (HPV) as necessary, but not sufficient, cause of cervical cancer has suggested the use of HPV testing in cervical cancer prevention. A large number of studies has provided evidence supporting its application (1) as primary screening test, (2) for triaging borderline cytology, (3) for follow-up after positive primary test but no abnormal histology and (4) as a test of cure. They also allowed a reasonably good definition of the appropriate policies and protocols, leading to the delivery of evidence-based guidelines resulting from a systematic review of the literature...

PURPOSE: DNA methylation in human papillomavirus-associated (HPV+) head and neck squamous cell carcinoma (HNSCC) may have importance for continuous expression of HPV oncogenes, tumor cell proliferation and survival. Here, we determined activity of a global DNA demethylating agent, 5-azacytidine (5-aza), against HPV+ HNSCC in pre-clinical models and explored it as a targeted therapy in a window trial enrolling patients with HPV+ HNSCC. EXPERIMENTAL DESIGN: Sensitivity of HNSCC cells to 5-aza treatment was determined, then 5-aza activity was tested in vivo using xenografted tumors in a mouse model...

Aims of the study were to evaluate Human Papillomavirus (HPV) and type-specific prevalence in four anatomical sites in HIV infected men who have sex with men (MSM) compared with HIV uninfected MSM. Participants were recruited among the attendees of Infectious Diseases Clinics in Central Italy. A trained medical practitioner collected by interview sociodemographic data and information on medical history, sexual behavior and drug use. Swabs from anal canal, oral cavity, urethral mucosa and coronal sulcus were tested for HPV DNA and genotyping...

The tumor suppressor gene TP53 is the most frequently mutated gene in human papillomavirus (HPV)-negative head and neck squamous cell carcinoma (HNSCC). It represents a known transcription factor that controls different microRNAs (miRNA) and target genes involved in the regulation of cellular stress, apoptosis and response to DNA damage. We used The Cancer Genome Atlas database to investigate the difference in transcriptome and proteome levels between mutated and wild-type TP53 HPV-negative HNSCC. Using different databases and an extensive literature review, we built the transcriptional and post-transcriptional network regulated by TP53...

We studied DNA methylation patterns of human papillomavirus (HPV) and tumor suppressor gene EPB41L3 in 148 anal and perianal biopsies to determine whether high levels of methylation would be associated with anal intraepithelial neoplasia (AIN). The most prevalent HPV type was HPV16, detected in 54% of the 30 benign biopsies, 33% of the 43 low-grade AIN (lgAIN), 82% of the 59 high grade AIN (hgAIN) and 4 of the 5 anal cancers. A methylation score was developed (0.561*HPV16me+0.439*EPB41L3) which had increasing values with severity of disease: the mean was 8...
