Study on the Correlation between Human Papillomavirus and Mycoplasma genitalium Combined with TCT Detection

Objective: This study aims to explore the correlation between human papillomavirus (HPV) and Mycoplasma genitalium (CT) combined with TCT detection in cervical cancer screening. Method: A cross-sectional study design was adopted, and a total of 609 women who came to seek medical treatment were recruited as the study subjects. Combination testing was evaluated on cervical cancer screening by testing the women for HPV, CT with TCT detection and analyzing the relationship of cervical lesions with HPV and CT infection. Results: The study results showed that 21.57% of the subjects were infected with both HPV and CT, and 48.42% of the cases had abnormal TCT results at the same time. Further data analysis showed that HPV infection was significantly associated with abnormal TCT outcomes (p < 0.05), suggesting a possible synergistic effect of the two infections in cervical lesions. The combined sensitivity and specificity of HPV, CT and TCT detection were 21.57% and 48.42%, respectively, which were significantly higher than that of single detection. Conclusion: In summary, the results of this study support the importance of combined HPV, CT, and TCT testing in cervical cancer screening, and propose the hypothesis that combined testing may improve screening effectiveness. However, further large sample studies are needed to confirm this conclusion and explore the prospects of combined testing in clinical practice.

Progress in the Research on the Relationship between Infection with Human Papillomavirus and Tumorigenesis

Human papillomavirus(HPV) is a DNA virus that infects the skin and mucous membranes of the human body. Approximately 80% of sexually active women are likely infected with HPV. Cervical cancer is one of the most common malignant tumors and is second in incidence only to breast cancer. Infection with high-risk HPV types is the main risk factor for cervical cancer, which is currently the only malignant tumor with a clearly defined etiology. HPV infection is also closely related to the incidence and development of other malignant tumors. In addition to cervical cancer, HPV can cause other urogenital tumors, as well as tumors in the digestive tract, lungs, eyes, skin, and other organ systems. This paper provides a review of the progress in HPV infection-related research and provides novel ideas for the study of tumor etiology and mechanisms.

Co-infection of Epstein-Barr virus and human papillomavirus in human tumorigenesis

Viral infections contribute to approximately 12%of cancers worldwide,with the vast majority occurring in developing countries and areas.Two DNA viruses,Epstein-Barr virus(EBV) and human papillomavirus(HPV),are associated with38%of all virus-associated cancers.The probability of one patient infected with these two distinct types of viruses is increasing.Here,we summarize the co-infection of EBV and HPV in human malignancies and address the possible mechanisms for the co-infection of EBV and HPV during tumorigenesis.

Evaluating the Association between Human Papillomavirus and Vulvar Cancer:A Comprehensive Analysis Using Bradford Hill Criteria

Background:The role of human papillomavirus(HPV)in the development of vulvar cancer(VC)has been widely studied,but findings have been inconsistent.Despite numerous meta-analyses exploring the potential link between HPV and VC,the association remains controversial due to inherent limitations in meta-analytic methods.Objectives:To address this controversy,the study aims to investigate the potential link between HPV and VC using the Bradford Hill criteria,which offer a more comprehensive framework for establishing causation.Methodology:The study began by extracting all relevant studies on the association between HPV and VC from the PubMed database.The potential links were then assessed by examining the data using the major postulates of the Bradford Hill criteria.To ensure the reliability of the findings,the methodologies of the identified studies were critically evaluated to account for possible false-negative and false-positive results.Results:The assessment of previous studies against the Bradford Hill criteria revealed that the major postulates were not fulfilled.Conclusion:Based on the findings,it can concluded that there is no causal association between HPV and VC.

Malakoplakia of the esophagus caused by human papillomavirus infection

Malakoplakia is a rare granulomatous disease probably caused by infection and characterized histologically by Michaelis-Gutmann bodies.We report a more rarely seen case esophageal malakoplakia in a 54-year-old woman.She presented with coughing while eating and drinking.Gastroscopy showed yellow nodules in the esophagus,and endoscopic ultrasonography showed a space-occupying lesion in the substratum of the esophageal mucosa.All findings highly resembled esophageal cancer.Histopathological examination finally indentified this space-occupying lesion as malakoplakia and not cancer.Immunohistochemistry showed that she had human papillomavirus(HPV) infection in the esophagus,which indicates that infection was responsible for the malakoplakia.This is believed to be the first case of malakoplakia in the esophagus,and more importantly,we established that HPV infection was the initiator of esophageal malakoplakia.

SEARCH FOR HERPES SIMPLEX VIRUS TYPE2（HSV－2）AND HUMAN PAPILLOMAVIRUS（HPV）IN THE NORMAL AND ABNORMAL CERVICAL SAMPLES

The specimens of 111 cervical carcinomas. 68 chronic cervicitis and 43 normal cervical exfoliated epithelial cells were examined for the presence of HSV2 DNA sequences with DNA hybridization using HSV2 BgL Ⅱ N fragment probe labelled by 32PdCTP. The result showed that the infection rates of HSV2 in the samples of cervical cancer.chronic cervicitis and normal epithelial cells were 1 4. 41 %(16/111). 27.94%( 19/68) and 25.58% ( 11/43),respectively. It was implied that early stages carcinogenesis of cervical epithelial cells might be correlated with the HSV2 infection.Sixteen HSV 2 positive samples of cervical carcinomas were also examined for the presence of the sequences homologous to human papillomavirus (HPV) type 6B/11. 16 and 18 DNA using dot blot hybridization (Tm17℃). The result indicated that 13 out of 16 were HPV 16 DNA hybridization positive accounting for 81. 2% of all HSV-2 positive samples and none of them were positive for HPV type 6B/11 and 18. The result indicated that double infection of HSV 2 and HPV16 in the same cervical carcinoma tissues may provide a strong evidence of the viral synergistic interaction in the induction of female cervical

THE DETECTION OF P53 GENE IN HUMAN CERVICAL CARCINOMA WITH AND WITHOUT HUMAN PAPILLOMAVIRUS INFECTION

The special primers Of p53 exon 7 as wed as HPV16 E6 and E7 ORFs (Opening Rending Frame) were used with PCR, PCR-SSCP technique, and 35 specimens of cervical carcinoma were examined. The results were as follows: ① HPV16 E6, E7 DNA was found in 25/35 specimens (71. 4%),which proved again HPV16 Infection an important event in cervical carcinogenesis. However only 11/35 (31.42% ) bad E6 and E7 ORFs simultaneously, 3/35 (8. 57%) and 11/35 (31. 42% ) had only E6 or E7 respectively. ② No mutation and LOH (Loss of Heterozygote) of p53 exon 7 were found in allof 35 specimens. Additionally in the present study, we developed a non-isotopic PCR-SSCP method.

Correlation between HPV sperm infection and male infertility

Human papillomavirus （HPV） is one of the most common sexually transmitted diseases which comprises a group of small DNA viruses that infect both cutaneous and mucous squamous epithelia. Liquid bead microarray technology （LBMA） were used to evaluate 24 HPV genotypes in confirmed fertile and infertile males of North China so that the effects of HPV infection on semen parameters and relationship with male infertility could be discussed. A total of 1138 subjects were recruited in this study; 142 were HPV-positive （12.48%）. Among 523 confirmed fertile males, only 35 were HPV-positive （6.70%）, and two of them had multiple infections. Among 615 infertile males, 107 were HPV-positive （17.4%）, and 29 of them had multiple infections. Infertile males had a relatively high HPV infection rate compared with confirmed fertile males. Sperm progressive motility （PR） and the normal morphology rate were significantly decreased in HPV-positive subjects. HPV-45, HPV-52, HPV-18, HPV-59 and HPV-16 infections were more frequently in infertile males. Hence, HPV infection is closely related to male infertility which will decrease sperm PR and morphology. HPV-45, HPV-52, HPV-18, HPV-59 and HPV-16 infection seems to be major risk factors.

Integration of human papillomavirus 18 DNA in esophageal carcinoma 109 cells

AIM:To detect human papillomavirus(HPV) DNA in esophageal carcinoma(EC) 109 cells and investigate the relationship between HPV and EC.METHODS:Genomic DNA and total RNA from EC109 cells were isolated.HPV DNA was detected by polymerase chain reaction(PCR) with the general primer sets of My09/11 and GP5 +/6 + for the HPV L1 gene and type-specific primer sets for HPV18 E6 and HPV18 E6-E7.Reverse transcription(RT) of mRNA isolated from EC109 cells was performed to produce a cDNA.And then a PCR-based protocol for the amplification of papillomavirus oncogene transcripts was used to analyze HPV18 DNA and integrated transcripts of HPV18 in the chromosomes of EC109 cells.The final nested PCR products were cloned into a pMD-18T vector and sequenced to analyze the chromosomal location of HPV integration.RESULTS:HPV18 DNA was detected in EC109 cells by PCR using the general primer sets of My09/11 and GP5 +/6 + for HPV L1 and the type-specif ic primer sets for HPV18 E6 and E6-E7 to generate products of 450 bp,150 bp,335 bp and 944 bp,respectively.Approximately 600 bp of integrated HPV18-specific transcript was identified.The final nested PCR product of integrated HPV18 DNA was cloned into a pMD-18T vector and sequenced to analyze the chromosomal location of HPV integration.Sequence alignment showed that the HPV18 sequence from EC109 cells was identical to that of the encoded early protein E7-E1 of the standard HPV18 strain X05015,and another partial gene sequence was identical to a partial sequence of human chromosome 8.CONCLUSION:Integration of the HPV genome into the host cell chromosome suggests that persistent HPV infection is vital for malignant cell transformation and carcinogenesis.

Human Papillomavirus as an Independent Predictor in Oral Squamous Cell Cancer

Aim There is an increasing evidence for the role of high risk human papillomavirus （HPV） in the pathogenesis of oral squamous cell carcinoma （OSCC）. The purpose of this study is to evaluate the relevance of HPV infection to the survival and prognosis of OSCC. Methodology Fifty-two patients with OSCC were followed from 4 to 88 months with a median of 50.7 months. HPV DNA was identified in formalin-fixed, paraffin-embedded tumor specimens by nested PCR with MY09/MY11 and GP5^＋/GP6^＋ primer pairs and the HPV genotype was determined by direct DNA sequencing. Association between the HPV status and risk factors for cancer as well as tumor-host characteristics were analyzed.Survival curves were calculated by the Kaplan-Meier method and analyzed using the log-rank test. Results HPV was found in 40.4% of the tumors with HPV16 accounting for 63.5%, HPV18 for 30.8%, HPV6 for 3.9% and HPVll for 1.8%. No infection with more than one HPV genotype was detected. HPV infection was significantly associated with poor histological grade, TNM stage Ⅰ -Ⅱ, alcohol usage and no smoking status. Multivariate analysis showed that HPV had an independent prognostic effect on the overall survival after adjusting other confounding factors such as histological grade, TNM stage and tobacco usage. The presence of HPV was significantly correlated with a better survival in patients with OSCC. Conclusion HPV infection can act as an independent predictor for the survival and prognosis of OSCC.

Safety and immunogenicity of human papillomavirus-16/18 AS04-adjuvanted vaccine in healthy Chinese females aged 15 to 45 years:a phase Ⅰ trial

Globally,about 70% of cervical cancers are associated with human papillomavirus (HPV)-16 or HPV-18 infection.A meta-analysis of epidemiologic studies in China showed that HPV was present in 98% of cervical cancer samples.The HPV-16/18 AS04-adjuvanted vaccine Cervarix has shown a high level of protection against HPV-16/18 infections and associated cervical lesions.This phase Ⅰ trial (NCT00549900) assessed the safety,tolerability,and immunogenicity of the vaccine in Chinese.Thirty healthy Chinese females,aged 15 to 45 years with a median age of 29.5 years,received three doses of Cervarix in Months 0,1,and 6.Safety was assessed via recording solicited local and systemic symptoms within 7 days and unsolicited symptoms within 30 days after each vaccination.Serious adverse events,new onset of chronic diseases,and other medically significant conditions were recorded throughout this trial.As an exploratory objective,HPV-16/18 antibody titers were determined by enzyme-linked immunosorbent assay in serum samples collected in Months 0 and 7.Pain at the injection site was the most frequently reported local symptom.Two subjects reported medically significant adverse events.Both cases were assessed as unrelated to vaccination by the investigator.In Month 7,100% seroconversion was observed for both anti-HPV-16 and anti-HPV-18 with high geometric mean antibody titers.HPV-16/18 AS04-adjuvanted vaccine,evaluated for the first time in Chinese females,was generally well tolerated and immunogenic,as previously shown in global studies.

Apoptosis of HeLa cells inhibited by human papillomavirus type 16 E6 protein interacting with hDaxx

Objective: To study the interaction of human papillomavirus type 16 (HPV16 E6) protein and human death domain associated protein (hDaxx) and its effect on apoptosis of HeLa cells to provide the experimental basis for exploring the oncogenic mechanism of HPV16 E6 protein. Methods: Recombinant vector of pGADT7/E6 or pGBKT7/hDaxx was con- structed. The interaction of E6 protein and hDaxx was detected by yeast two-hybrid system. Their expression in yeast was detected by Western blotting. The eukaryotic plasmids of E6 and hDaxx were co-transfected into HeLa cells. Apoptosis was induced by 5-FU. The apoptotic rate was measured by flow cytometry (FCM). Results: E6 protein had intracellular interaction with hDaxx. The apoptotic rate was rising with the increase in the transfection quantity of pcDNA3.1 (-) / hDaxx in pcDNA3.1 (-) /E6 and pcDNA3.1 (-) / hDaxx co-transfected cells. The difference was significant ( P < 0. 01). Conclusion: There is intracellular interaction between HPV16 E6 protein and hDaxx. The over-expression of hDaxx can increase the sensitivity of E6 protein positive HeLa cells to 5-FU. The effect was in a dose dependent manner. HPV16 E6 protein inhibited the apoptosis of HeLa cells by interacting with hDaxx.
