  • Cancer of the cervix is the third most common cancer in women worldwide, more than 85% of the cases occurring in developing countries such as China. In China, since a national cancer registry is already set up but with geographically limited data generated, the burden of cervical cancer is believed to be underestimated. High-risk human papillomavirus (HR-HPV) prevalence among women attending routine cervical cancer screening programs has been shown to correlate well with cervical cancer incidence rates based on independently obtained HPV prevalence data as well as findings for the worldwide cervical cancer burden. Therefore, reviewing data on HR-HPV prevalence in population-based screening studies and hospital-based case studies will be important in the context of better understanding the cervical cancer burden and for the evaluation of the potential impact of HPV vaccination in the country. With the advent of prophylactic vaccines, significant progress is likely to be made in cervical cancer prevention. This article reviews available data on the HPV epidemiology over a 12-year time period (2001-2012) in mainland China under different epidemiological aspects: by age group of study population, by ethnicity, by geographic area, as well as time period. The authors also review the potential acceptability of HPV vaccination among Chinese women.

  • Human papillomavirus (HPV), especially type 16 and 18, has been closely associated with carcinomas and uterine cevical cancer, recently. From in vitro assays, E6 and E7 genes of HPV16 are closely linked with transformation of cell lines of rodent fibroplasts. However, the transforming activity of E6 and E7 genes of HPV type 16 in vivo has not been fully elucidated. For explaining this mechanism, we prepared a expression system with the promoter of mouse mammary tumorvirus long terminal repeat and E6E7's open reading frames. This expression system was introduced in rodent cell lines, No. 7, 3Y1 and shown normal transforming abilities. And, we produced transgenic mice with E6, E7 expression system. These transgenic mice were confirmed from Southern blot analysis. One male of them was observed enlargement of the testis after 5 months postdelivery.

  • Purpose: The purpose of this study was to apply Ajzen's theory of planned behavior to identify factors that affect undergraduate women's decisions to receive human papillomavirus(HPV) vaccination. Method: The research design for this study was a descriptive survey design using convenience sampling. Data collection was done using self-report questionnaires with 254 undergraduate students in G city. Data were analyzed using percentage, mean, standard deviation, t-test, ANOVA, Mann-Whitney U test, Pearson correlation analysis and multiple regression with the SPSS Win 20.0 Program. Results: The mean score of intention to receive HPV vaccine was $3.88{\pm}1.05$ out of a possible 7. Intention to receive HPV vaccine showed a significantly positive correlation with attitudes (r=.26, p<.001), subjective norm (r=.51, p<.001), perceived behavior control (r=.41, p<.001) to receive HPV vaccination. In the multiple regression analysis, subjective norm and perceived behavior control to receive HPV vaccine were significant predictors and explained 33.7% of intention to receive HPV vaccine. Conclusion: Results of this study show that there are significant factors affecting the intention of undergraduate women to receive HPV vaccination. Also, strategies emphasizing subjective norm and perceived behavior control in obtaining HPV vaccination should be taken into account in developing educational programs.

  • To explore the application of DNA chip technology for the detection and typing of Human Papillomavirus (HPV), the HPV6, 11, 16 and 18 gene fragments were isolated and printed onto aminosilane-coated glass slides by a PixSys 5500 microarrayer as probes to prepare the HPV gene chips. HPV samples, after being labeled with fluorescent dye by restriction display PCR (RD-PCR) technology, were hybridized with the microarray, which was followed by scanning and analysis. The experimental condition for preparing the HPV gene chips was investigated, and the possibility of HPV genotyping using gene chips was discussed. The technique that was established in this study for preparing HPV gene chips is practical. The results of the present study demonstrated the versatility and inspiring prospect of using this technology to detect and genotype HPV.

  • Human papillomavirus(HPV) is epitheliotrophic virus invading the anogenital tract and the upper aerodigestive tract HRV produces a diversity of benign and maljgnant tumors. In this study, the author determined the frequency of association of human papillomavirus(HPV) and laryngeal carcinomas and investigated the significance of HRV infection of different subtypes in the tumorigenesis of laryngeal carcinoma. Laryngeal squamous cell cancinomas from 34 patients who did not have preexisting papillomas by clinical history were retrieved from formalin-fixed, paraffin-embedded blocks and analyzed for HPV. Nineteen cases were tumors of the true vocal folds, 11 were supraglottic and 4 were transglottic. HPV detection was dane using polymerase chain reaction amplification with HPV L$_1$consensus primer. HPV type was determined by the same method using HPV-6, 11 and 16,-18 type-specific E6 primers. The results were as follows : 1) HPV DNA was detected in 7 cases among the 34 patients(20.6%). According to the type of HPV DNA HPV-11 was detected in 3 cases, HPV-16 was detected in 2 cases and HPV-6 and HPV-18 were detected in 1 case, respectively. 2) These 7 HPV-positive patients were advanced cancinoma cases. From these results, we concluded that HPV was thought to be the etiological factor of laryngeal squamous cell carcinomas.

  • The leading cause of cancer mortality globally amongst the women is due to human papillomavirus (HPV) infection. There is need to explore anti-cancerous drugs against this life-threatening infection. Traditionally, different natural compounds such as withaferin A, artemisinin, ursolic acid, ferulic acid, (-)-epigallocatechin-3-gallate, berberin, resveratrol, jaceosidin, curcumin, gingerol, indol-3-carbinol, and silymarin have been used as hopeful source of cancer treatment. These natural inhibitors have been shown to block HPV infection by different researchers. In the present study, we explored these natural compounds against E6 oncoprotein of high risk HPV18, which is known to inactivate tumor suppressor p53 protein. E6, a high throughput protein model of HPV18, was predicted to anticipate the interaction mechanism of E6 oncoprotein with these natural inhibitors using structure-based drug designing approach. Docking analysis showed the interaction of these natural inhibitors with p53 binding site of E6 protein residues 108-117 (CQKPLNPAEK) and help reinstatement of normal p53 functioning. Further, docking analysis besides helping in silico validations of natural compounds also helped elucidating the molecular mechanism of inhibition of HPV oncoproteins.

  • Human papillomavirus (HPV) infection is the leading cause of cancer mortality among women worldwide. The molecular understanding of HPV proteins has significant connotation for understanding their intrusion in the host and designing novel protein vaccines and anti-viral agents, etc. Genomic, proteomic, structural, and disease-related information on HPV is available on the web; yet, with trivial annotations and more so, it is not well customized for data analysis, host-pathogen interaction, strain-disease association, drug designing, and sequence analysis, etc. We attempted to design an online reserve with comprehensive information on HPV for the end users desiring the same. The Human Papillomavirus Proteome Database (hpvPDB) domiciles proteomic and genomic information on 150 HPV strains sequenced to date. Simultaneous easy expandability and retrieval of the strain-specific data, with a provision for sequence analysis and exploration potential of predicted structures, and easy access for curation and annotation through a range of search options at one platform are a few of its important features. Affluent information in this reserve could be of help for researchers involved in structural virology, cancer research, drug discovery, and vaccine design.

  • Purpose: The purpose of this study was to identify effects of attitude, subjective norm, and perceived behavior control toward Human Papillomavirus (HPV) on HPV vaccination intention in female high school students. Methods: Subjects of this study were female students aged 16 to 17 years, the optimal age group of HPV vaccination, arbitrarily selected from three high schools in B city. A total of 140 students agreed to participate in this study. Data were analyzed using descriptive statistics, t-test, ANOVA, correlation, and stepwise multiple regression. Results: Attitude, subjective norm, and perceived behavior control toward HPV were factors influencing HPV vaccination intention of subjects. Perceived behavior control toward HPV vaccination was the most influential factor. These factors accounted for 49% of HPV vaccination intention. Conclusion: These results suggest a need to increase perceived behavior control to increase HPV vaccination intention. The government needs to establish a national policy system such as financial support for HPV vaccines and free vaccinations so that students are aware that HPV vaccines can be easily inoculated.

  • One cervical cancer cell line, C9, carrying human papillomavirus type 18 (HPV18) genes that is one of the major etiologic concoviruses for cervical cancer was characterized. This cell line was further characterized for its capacity related to the epithelial cell proliferation, stratification and differentiation in reconstituted artificial epithelial tissue. The in vitro construction of three dimensional artificial cervical opithelial tissue has been engineered using C9 epithelial cancer cells, human foreskin fibroblasts and a matrix made of type I collagen by organotypic culture of epithelial cells. The morphology of paraffin embedded artificial tissue was examined by histochemical staining. The artificial epithelial tissues were well developed having multilayer. However, the tissue morphology was similar to the cervical tissus having displasia induced by HPV infection. The characteristics of the artificial tissues were examined by determinining the expression of specific marker proteins. In the C9 derived artificial tissues, the expression of EGF receptor, as epithelial proliferation marker proteins for stratum basale was observed up to the stratum spinosum. Another epithelial proliferation marker for stratum spinosum, cytokerations 5/6/18, were observed well over the stratum spinosum. For the differentiation markers, the expression of involucrin and filaggrin were observed while the terminal differentiation marker, cytokeratins 10/13 was not detected at all. Therefore the reconstituted artificial epithelial tissues expressed the same types of differentiation marker proteins that are expressed in normal human cervical epithelial tissues but lacked the final differentiation capacity representing characteristics of C9 cell line as a cancer tissue devived cell line. Expression of HPV18 E6 oncoprotein was also observed in this artifical cervical opithelial tissue though the intensity of the staining was weak. Thus this artificial epithelial tissue could be used as a useful model system to examine the relationship between HPV-induced cervical oncogenesis and epithelial cell differentiation.
