Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Lonicera japonica Thunb. has been used as a traditional medicinal herb in China for thousands of years for its heat-clearing and detoxification effects. In recent years, experimental and clinical studies have shown that some Lonicera japonica-containing Chinese medicine prescriptions have been used to treat intraepithelia neoplasia caused by human papilloma virus (HPV) infection. However, its bioactive molecules and mechanism of action have not been fully explored. AIM OF THE STUDY In this study, Lonicera japonica-derived exosomes was extracted and exosomal miR2911 was identified. Bioinformatic analysis indicated that miR2911 potentially binds to the sequence of HPV. The mechanism of miR2911 action on HPV and the effect of exosomal miR2911 on HPV-induced cervical cancer cells were investigated. METHODS The potential targets of miR2911 on the HPV sequence were predicted and confirmed by using RNAhybrid and dual-luciferase reporter assays. Lonicera japonica exosomes were characterized by transmission electronic microscopy and zeta sizer analysis. RT-qPCR was used to measure miR2911 concentration in various tissues and exosomes. Synthetic miR2911 and GFP-E6/E7 plasmids were transfected into HEK293T cells to examine the effect of miR2911 on E6/E7 gene expression. The effects of miR2911 on endogenous E6/E7 mRNA and protein levels were detected in HPV16/18-positive cervical cancer cells by RT-qPCR and Western blotting. The proliferation and apoptosis of CaSki, SiHa and HeLa cells by the treatment of miR2911 or miR2911-containing exosomes were examined by CCK8, colony formation and flow cytometry assays. RESULTS MiR2911 is found to be enriched in various Lonicera japonica tissues, and is stably present in Lonicera japonica-derived exosomes. It is observed that MiR2911 directly binds to E6 and E7 oncogenes of HPV16/18, leading to the suppression of their protein expression. In addition, the endogenous E6/E7 mRNA and protein levels were significantly decreased by using miR2911 treatment in HPV16/18-positive cervical cancer cells. Furthermore, both miR2911 and miR2911-containing exosomes inhibited cell proliferation of SiHa, CaSki and HeLa cells, meanwhile inducing the cell apoptosis through E6/E7-p53/Caspase3 axis. CONCLUSION Our findings indicate that miR2911, an active component present in Lonicera japonica exosomes, inhibits proliferation and induces apoptosis of cervical cancer cells by targeting the E6/E7 genes of HPV16/18. Thus, Lonicera japonica-derived exosomal miR2911 has implications for the development of novel therapeutic strategies for the treatment of HPV-associated cervical cancers.

Abstract
BACKGROUND Human papillomavirus (HPV)-related oropharyngeal cancer (OPC) incidence is increasing among men. Biomarkers that can identify oral HPV16/18 infections likely to persist, the obligate precursor for HPV-OPC, are needed. METHODS We assessed the association between oral Epstein-Barr virus (EBV) and oral HPV16/18 persistence among 63 men in the HPV Infection in Men Study who tested positive for HPV16/18 at the baseline visit. Control of oral coinfections, including EBV, could serve as a biomarker of immune competence and the ability to control oral HPV. RESULTS Detection of oral EBV was significantly associated with oral HPV16/18 ≥12-month persistence. CONCLUSIONS Detection of oral EBV deserves evaluation as a biomarker for oral HPV persistence and HPV-related OPC.

Abstract
Low-grade cervical squamous intraepithelial lesion is a precancerous neoplasia that has appreciable probability to evolve into malignancy. To explore the prognostic value of HPV 16/18 genotyping and geminin mRNA quantification in predicting the progressiveness of LSIL. We recruited 212 participants who were negative for intraepithelial lesion or malignancy (NILM 76), low-grade squamous intraepithelial lesion (LSIL 85), high-grade squamous intraepithelial lesion (HSIL 36) and cervical intraepithelial neoplasia grade cervical cancer grade 3, (CIN3 15) patients. Tissues were obtained during excisional treatment. HPV 16/18 genotyping and geminin mRNA qRT-PCR were performed. HPV 16/18 positivity rate and geminin mRNA level were integrated with the clinical parameters into a multivariate logistic model. Area under curve was yielded based on receiver operation curve derived from this multivariate logistic model. Follow-up visits were performed to LSIL patients with progression. HSIL patients have higher HPV 16/18 positivity rate and geminin mRNA levels than LSIL. Among HSIL, CIN3 have higher HPV 16/18 positivity rate and geminin mRNA levels. Multivariate logistic analysis showed that HPV 16/18 positivity and geminin mRNA expression status are independent factors for differentiating HSIL and LSIL. The baseline HPV 16/18 positivity rate and geminin mRNA levels of 18 LSIL patients who developed HSIL are significantly higher than non-progressive LSIL patients. The values examined at follow-up timepoints were also higher than baseline. These results suggest that geminin is implicated in the progression of LSIL and combining HPV 16/18 genotyping and geminin mRNA qRT-PCR could potentially differentiating the progressive LSIL and improve the efficacy of clinical intervention.

Abstract
Human papillomavirus (HPV) infection-dependent cervical cancer is one of the most common gynecological cancers and often becomes aggressive, with rapid proliferation, invasion/migration, and drug resistance. Here, 135 fresh human cervical squamous cell carcinoma (CSCC) tissue specimens, comprising 21 adjacent normal (AN), 30 cervical intraepithelial neoplasia (CIN1-3 ), 45 CSCC, and 39 drugs (chemo-radiation)-resistant cervical tumor (DRCT) tissues were included. HPV-positive (HeLa, SiHa), HPV-negative (C33A), and cisplatin-resistant (CisR-HeLa/-SiHa/-C33A) cell lines were used for in vitro studies. HPV16/18 oncoproteins E6/E7, pERK1/2, and glycogen synthase kinase-3 (GSK3) and the matrix metalloproteinases (MMPs) MMP-9/-2 were assessed using immunohistochemistry, WB, and gelatin zymography. HPV16/18 infection was observed in 16.7% of the CIN1-3 , 77.8% of the CSCC, and 89.7% of DRCT samples. Total and inactive GSK3β expressions were associated with overall CSCC progression (p = 0.039 and p = 0.024, respectively) and chemoresistance (p = 0.004 and p = 0.014, respectively). Positive correlations were observed, between the expression of E6 and pGSK3β expression (p = 0.013); E6 and CSCC progression (p < 0.0001)/drug resistance (p = 0.0001). CisR-HeLa/-SiHa was more dependent on pGSK3β, and activation of GSK3 by SMIs (iAkt), treatment with nimbolide, or knockdown of E6/E7 reduced cisplatin resistance and promoted apoptosis. Hence, the activation of GSK3β with nimbolide and iAkt can be exploited for therapeutic interventions of cervical cancer.

Abstract
Persistent infections with some types of human papillomavirus (HPV) constitute the major etiological factor for cervical cancer development. Nanog, a stem cell transcription factor has been shown to increase during cancer progression. We wanted to determine whether Nanog could modulate transcription of E6 and E7 oncogenes. We used luciferase reporters under the regulation of the long control region (LCR) of HPV types 16 and 18 (HPV16/18) and performed RT-qPCR. We found that Nanog increases activity of both viral regulatory regions and elevates endogenous E6/E7 mRNA levels in cervical cancer-derived cells. We demonstrated by in vitro mutagenesis that changes at Nanog-binding sites found in the HPV18 LCR significantly inhibit transcriptional activation. Chromatin immunoprecipitation (ChIP) assays showed that Nanog binds in vivo to the HPV18 LCR, and its overexpression increases its binding as well as that of c-Jun. Surprisingly, we observed that mutation of AP1-binding sites also affect Nanog's ability to activate transcription, suggesting cooperation between the two factors. We searched for putative Nanog-binding sites in the LCR of several HPVs and surprisingly found them only in those types associated with cancer development. Our study shows, for the first time, a role for Nanog in the regulation of E6/E7 transcription of HPV16/18.

Abstract
Introduction The aim of this study was to determine whether ZNF582 gene methylation and tissue protein expression can be used as a tool with high sensitivity and specificity for cervical cancer screening. We analyzed the correlation between promoter methylation of ZNF582 gene and cervical cancer and high risk HPV16/18 infection. Methods Tissue samples of normal cervical or chronic cervicitis (n=51), CIN (cervical intraepithelial neoplasia) (n=35), and cervical carcinoma (n=68) were tested for HPV16/18 infection by polymerase chain reaction (PCR). We also detected the methylation status of the ZNF582 gene promoter in the same tissues by methylation-specific PCR (MSP), then analyzed the correlation between ZNF582 promoter methylation and HPV16/18 infection. Immunohistochemistry was used to analyze ZNF582 gene expression in 152 cervical tissues. We detected ZNF582 mRNA expression in cervical tissues (including cancer and non-cancer) by real-time fluorescence quantitative PCR (qPCR). Results Among 93 high-grade cervical lesions (CINII and above) and cervical cancer samples, 57 cases were positive for HPV16/18 infection and 36 cases were negative. ZNF582 gene methylation occurred in 9 out of 51 cases in normal cervical tissues (17.6%), 16 of 35 cases in CIN tissues (45.7%), and 50 of 68 cases in cervical cancer (73.5%). The differences in methylation rate of the three groups were statistically significant (P<0.05). The ZNF582 methylation rate in the positive HPV16/18 infection group was 73.7%, while the negative group was 63.9%. Compared with normal tissues, ZNF582 protein was highly expressed in cervical cancer tissues, but mRNA expression was low. Conclusion While ZNF582 protein is highly expressed in cervical cancer tissues, it was not sufficient for use as a standard for cervical cancer staging. On the other hand, ZNF582 promoter methylation had high specificity and sensitivity in detecting CINII and highly diseased cervical lesions and could be used as a diagnostic marker for cervical cancer of women.

Abstract
PURPOSE This study aimed to conduct a meta-analysis to investigate the distribution of EBV and HPV stratified according to histological NPC type. MATERIALS & METHODS We performed a meta-analysis to produce pooled prevalence estimates in a random-effects model. We also performed calculations for attributable fractions of viral combinations in NPC, stratified according to histological type. RESULTS There was a higher prevalence of HPV DNA in WHO Type I (34.4%) versus WHO Type II/III (18.4%). The attributable fractions of WHO Type I NPC was predominantly double negative EBV(-) HPV(-) NPC (56.4%), and EBV(-) HPV(+) NPC (21.5%), in contrast to the predominant infection in WHO Type II/III which was EBV(+) HPV(-) NPC (87.5%). Co-infection of both EBV and HPV was uncommon, and double-negative infection was more common in WHO Type I NPC. CONCLUSION A significant proportion of WHO Type I NPC was either double-negative EBV(-)HPV(-) or EBV(-)HPV(+).

Abstract
Objectives: To identify the prevalence of high-risk human papillomavirus (HPV) genotypes 16 and 18 among patients with oral squamous cell carcinoma (OSCC) in Thailand and investigate the associations of p16 expression and HPV16/18 with the demographic, clinicopathologic, and risk parameters. Materials and Methods: A total of 403 formalin-fixed paraffin-embedded OSCC specimens from four centers in four regions were obtained. p16 expression was evaluated by immunohistochemistry. The detection of HPV16/18 DNA was performed by polymerase chain reaction. Results: Of all, 172 specimens (42.7%) were presented with amplifiable extracted DNA. Among these, 62.8% were positive for p16, 8.1% were positive for HPV16/18, and 5.8% were positive for both methods. Of all HPV-positive specimens, HPV18 was detected in 57.1%; HPV16 in 14.3%; and HPV16 and 18 (co-infection) in 28.6%. The prevalence of HPV16/18 varied between centers, with the highest rate in the northern center (20.0%). There was no significant correlation between p16 expression and HPV16/18. There were no significant associations of p16 expression and/or HPV16/18 with all variables. Conclusions: The prevalence of HPV16/18 infection in OSCC geographically varied in Thailand, with the highest rate in the northern region. Poor correlation between p16 and HPV16/18 suggests p16 not be used as a surrogate marker for HPV-positive OSCC.

Abstract
Objective: Human papillomavirus (HPV) vaccination was introduced in Japan in
April 2013, as a national immunization program for girls aged 12–16 years, after an
initial introduction in 2010 as a public-aid program for girls aged 13–16 years. The
Yuri-Honjo district had the highest vaccine coverage among women aged 17–51 years in 2017,
due to the original public-aid program. The aim of this study was to evaluate the
differences in the vaccine types of HPV16/18 infections between 2008–2012 (pre-vaccine
era) and 2013–2017 (vaccine era). Materials and Methods: We evaluated whether HPV vaccination was associated
with a decrease in the prevalence of HPV16/18 and high-risk HPV and the incidence of
HPV-associated cervical lesions. A total of 1,342 women aged 18–49 years, covering both
the pre-vaccine and vaccine eras, who visited Yuri Kumiai General Hospital and underwent
HPV genotype tests from June 2008 to December 2017 were compared. Results: Among women aged 18–24 years with higher vaccine coverage (68.2%),
the prevalence of HPV16/18 and high-risk HPV decreased from 36.7% and 69.4%, respectively,
in the pre-vaccine era to 5.8% and 50.0%, respectively, in the vaccine era (p=0.00013 and
p=0.047, respectively). Among those with cervical intraepithelial neoplasia grade 2− and
grade 2+, HPV16/18 prevalence decreased from 30.0% to 2.7% (p=0.0018) and from 81.8% to
36.4% (p=0.030), respectively. In this age group, the rate of HPV16/18 positivity
decreased significantly. Among age groups with lower vaccine coverage, HPV prevalence did
not significantly differ between the two eras. Conclusion: The prevalence of HPV16/18 and high-risk HPV significantly
decreased in women aged 18–24 years, most of whom were vaccinated. HPV vaccination
effectively reduced the prevalence of HPV16/18 infections in the Yuri-Honjo district.

Abstract
OBJECTIVE To quantitatively measure the expression of low-density lipoprotein receptor-related protein 1B gene (LRP1B) in normal and cervical squamous cell carcinoma tissues and explore the correlation between LRP1B gene and age, degree of tumor differentiation, clinical staging, degree of infiltration, lymph node metastasis and the infection of human papilloma virus (HPV) 16/18. METHODS Forty patients diagnosed with cervical squamous cell carcinoma and 20 healthy subjects were recruited. The expression of LRP1B mRNA was quantitatively measured by in situ hybridization using LRP1B oligonucleotide probe. The expression of HPV16/18 in the cervical squamous cell carcinoma specimen was investigated. RESULTS Among 40 cervical carcinoma samples, the expression level of LRP1B mRNA was down-regulated in 22. Among 20 healthy controls, low expression of LRP1B mRNA was observed in 3. The negative rate of LRP1B mRNA expression in the cervical carcinoma group was significantly lower compared with that in the normal tissues (P<0.05). The positive rate of HPV16/18 in patients with negative LRP1B was significantly higher than that in their counterparts positive for LRP1B (P<0.05). In the cervical carcinoma group, the expression of LRP1B mRNA was not correlated with age, degree of tumor differentiation or clinical staging (all P>0.05). The expression level of LRP1B mRNA in patients with serous membrane infiltration and lymph node metastasis was significantly down-regulated (both P<0.05). CONCLUSION LRP1B is lowly expressed in cervical squamous cell carcinoma tissues, suggests LRP1B gene probably acts as a new tumor suppressor gene. LRP1B gene alteration and HPV16/18 infection play a coordinating role in the incidence of cervical cancer. LRP1B expression is intimately correlated with the incidence and metastasis of cervical squamous cell carcinoma.

Abstract
BACKGROUND Cervical cancer remains an important cause of cancer mortality for Mexican women. HPV 16/18 typing may help to improve cervical cancer screening. Here we present the prevalence of high-risk human papillomavirus (hrHPV) including HPV16 and HPV18 from the FRIDA (Forwarding Research for Improved Detection and Access) population. METHODS Beginning in 2013, we recruited 30,829 women aged 30-64 in Tlaxcala, Mexico. Cervical samples were collected and tested for 14 hrHPV genotypes (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68). We used logistic regression to estimate odds ratios with 95 % confidence intervals for hrHPV infections according to putative risk factors. RESULTS Prevalence of infection with any of the 14 hrHPV types was 11.0 %. The age-specific prevalence of all hrHPV formed a U-shaped curve with a higher prevalence for women aged 30-39 and 50-64 than women aged 40-49. Across all age groups, 2.0 % of women were positive for HPV16 and/or HPV18 (HPV16/18), respectively. HPV16/18 prevalence also showed a U-shaped curve with increased prevalence estimates for women aged both 30-39 and 60-64. Both prevalence curves had a significant quadratic age coefficient. Infections with hrHPV were positively associated with an increased number of lifetime sexual partners, a history of sexually transmitted disease, being unmarried, use of hormonal contraception, having a history of smoking and reported condom use in the multivariate model. CONCLUSIONS The FRIDA population has a bimodal distribution of both hrHPV and HPV16/18 positivity with higher prevalences at ages 30-39 and 60-64. These findings will help to evaluate triage algorithms based on HPV genotyping. TRIAL REGISTRATION The trial is registered with ClinicalTrials.gov, number NCT02510027 .

Abstract
Background Opportunistic screening in hospitals is widely used to effectively reduce the incidence rate of cervical cancer in China and other developing countries. This study aimed to identify clinical risk factor algorithms that combine gynecologic examination and molecular testing (paired box gene 1 (PAX1) or zinc finger protein 582 (ZNF582) methylation or HPV16/18) results to improve diagnostic accuracy. Methods The delta Cp of methylated PAX1 and ZNF582 was obtained via quantitative methylation-specific PCR in a training set (57 CIN2− and 43 cervical intraepithelial neoplasia ≥grade 3 (CIN3+) women), and the individual and combination gene sensitivities and specificities were determined. The detection accuracy of three algorithms combining gynecologic findings and genetic test results was then compared in a randomized case-control study comprising 449 women referred for colposcopic examination by gynecologists in the outpatient department of Xiangya Hospital between November 2011 and March 2013. Results Significant association was observed between CIN3+ and methylated PAX1 or ZNF582 in combination with HPV16/18 (OR:15.52, 95 % CI:7.73–31.18). The sensitivities and specificities of methylated PAX1 or ZNF582 combined with HPV16/18 for CIN3+ women were 89.2 and 76.0 %, or 85.4 and 80.1 %, respectively. Of the three algorithms applied to cohort data and validated in the study, two indicated 100 % sensitivity in detecting cervical cancer and a low rate of referrals for colposcopy. Conclusions These algorithms might contribute to precise and objective cervical cancer diagnostics in the outpatient departments of hospitals in countries with high mortality and low screening rates or areas with uneven resource distribution.

Abstract
In the present study, we analyzed (1) the type of HPV infection and (2) the frequency of loss of heterozygosity and microsatellite imbalance (LOH/MSI) in normal cytology and cervical intraepithelial neoplasia (CIN1-3). The cytological material included: low-grade squamous intraepithelial lesions (CIN1, n = 11), high-grade lesions (CIN2 and CIN3, n = 13), and cytologically normal cells from non-neoplastic cervical samples (n = 8). HPV genotyping was done using RealLine HPV 16/18 kit. We used 20 microsatellite markers from: 1p31.2, 3p14.3, 3p21.3, 3p22.2, 3p24.2, 3p25.3, 7q32.2, 9p21.3, 11p15.5, 12q23.2, and 16q22.1. LOH/MSI was correlated with clinicopathological parameters. The presence of HPV DNA was revealed in 78.13 % samples, including normal cytology. LOH/MSI was the most frequent for: 3p25.3 (39 %), 3p22.2 (20.83 %), 3p24.2 (20 %), and 3p14.3 (16.67 %). It was demonstrated that D3S1234 (FHIT; 3p14.3), D3S1611 (MLH1; 3p22.2), D3S1583 (RARB; 3p24.2), D3S1317 and D3S3611 (VHL; 3p25.3) could differentiate patients with CIN2/CIN3 versus CIN1, showing significantly higher frequency in CIN2/CIN3. LOH/MSI frequency for other than 3p markers was lower, 10-22.2 %. The simultaneous occurrence of LOH/MSI for several markers (OFAL) was higher in CIN2/CIN3. Significant differences in OFAL were found between samples with versus without HPV infection. In HPV-positive patients, significant differences in OFAL were found between normal cytology, CIN1 and CIN2/CIN3. HPV infection influences the increase in LOH/MSI frequency, especially in tumor suppressor gene loci. Several studied microsatellite markers seem to be useful for CIN grading. Hopefully, the obtained results, if confirmed on larger patient cohort, would allow creating a panel of markers supporting clinical diagnosis in patients with HPV infection.

Abstract
BACKGROUND Although cervical uterine cancer is a second form of cancer among women, but it occupies fifth form among all cancer types. METHODS In the present study, human papillomavirus (HPV) and herpes simplex virus 2 (HSV-2) in cervical cancer patients by using real time polymerase chain reaction (PCR) technique and the relation between their viral loads were investigated. 156 cervical carcinoma tissues were collected from married women in health centers in Isfahan, Iran. RESULTS The results showed that among 156 specimens, 58.97%, 45.51% and 7.05% were positive for HPV DNA, HPV-16 and HPV-18 respectively. Only in 2.3% specimens, HSV-2 and HPV-16 were positively detected where viral load HSV-2 in conjunction with HSV-16 dramatically increased. CONCLUSION Thus the present study not only confirmed that viral load of HPV-16 is more than other HPV types, but also in possible conjunction with HSV-2, both rates will significantly increase.

Abstract
Objective : To determine the relations between human papilloma viruses type 16 and type 18 infection and the expression of p53 protein in invasive ductal carcinoma. Methods : We detected the expression of HPV 16/18 DNA and p53 protein in invasive ductal carcinoma in 45 cases, breast fibroadenoma in 20 cases and normal breast tissues in 20 cases. HPV detection was performed on paraffin sections using biotin-labeled probes by in situ hybridization and p53 protein expression was evaluated by immunohistochemistry. Results : The expression rate of HPV 16/18 DNA and p53 protein in invasive ductal carcinoma is significantly higher than those in breast fibroadenoma and normal breast tissues (p<0.05); the expression in cases with axillary lymph node metastasis is dramatically higher than those without (p<0.05); the expression of p53 protein increases with TMN staging advance. The expression of HPV16/18 DNA was significantly correlated with the expression of p53 protein (p<0.05). Conclusion : Both HPV16/18 infection and p53 mutation participate the occurrence and progress of invasive ductal carcinoma, and HPV 16/18 infection may be the major factor to cause p53 mutation.
