E7 Oncogene

Introduction. High indices of prostate cancer (PC) incidence and mortality as well as high speed of growth of these figures testify to urgency of research into PC origin as well as means of its prophylaxis. The problem of possible PC association with oncogenic human papillomaviruses (HPV) is still being disputable. Objective: to test whether surgical materials from PC patients in Russia harbour E7 oncogene of HPV type 16 (HPV16), the main HPV type responsible for cervical cancer. Materials and methods. Prostate tissues excised in the course of radical prostatectomy from 17 PC patients were tested by polymerase chain reaction. For better DNA preservation cryopreserved tumor specimens not treated with either formalin or paraffin were used. The PC typical multifocal type of growth was taken into account by microdissecting of cryostate cuts to accumulate homogeneous cells (cancerous, dysplastic or normal). Results. HPV16 E7 was registered in prostate tissues of 7 patients out of 17 examined including all those 5 cases for which DNA had been isolated from homogeneous sites of cancer cells. Conclusion. The result obtained enables one to admit that HPV16 may be harbored in prostates of Russian PC patients not infrequently.

The Given

Introduction . High prostate cancer (PC) incidence rates testify to importance of research into genesis of the given disease and means of its prevention. The item of oncogenic human papillomaviruses (HPVs) participance in PC origination is still being the subject of debates. If association of PC with HPV is proven prophylaxis of the given disease becomes possible by means of inoculating boys with the vaccines made for cervical cancer (CC) prevention.Objective: to test whether prostate tissues surgically removed from PC patients harbor oncogen E7 of HPV18 – the second most common HPV type responsible for CC.Materials and methods . The study was carried out on prostate glands of 17 PC patients surgically treated in N.N. Blokhin National Medical Research Center of Oncology. Detection of HPV18 oncogen E7 was done by polymerase chain reaction. To elevate polymerase chain reaction sensitivity DNA was isolated from homogeneous cell populations collected by means of microdissections from cryopreserved PC specimens.Results . Amplification products corresponding to HPV18 oncogen E7 were registered in tests from 2 PC patients.Conclusion . HPV18 oncogen E7 was detected in surgically removed prostate tissues of 2 PC patients. In the aggregate with our previous result (7 HPV16-positive PC cases in the same group of 17 patients) the given result enables one to presume participance of oncogenic HPVs in PC genesis. The problem deserves further study.

In developing countries, cervical cancer is the most common cause of cancer related to mortality in women. But the epidemiology of human papillomavirus (HPV) in different areas of Bangladesh is largely unknown both in risk groups and in the general population. The objective of the present study was to determine the risk factors associated with having HPV and the prevalence of high-risk HPV types among women with highrisk behaviour and to assess its potential impact on preventive strategies as the sex workers are at increased risk for sexually transmitted infections (STI), HPV and hence cervical cancer. Cervical swab from 293 sex workers in Dhaka City between August and September 2003 and between February 2005 and May 2006 were screened for HPV DNA using an HPV short fragment (E6) polymerase chain reaction (PCR) based assay. HPV positive samples were genotyped with nested multiplex polymerase chain reaction (NMPCR) for the highrisk types. The overall HPV prevalence in sex workers was 75.8%, whereas for the high risk type it was 49.8%. Prevalence of single genotype and multiple types of HPV was 33.1 and 16.7% respectively. The most prevalent high-risk HPV types, in order of prevalence rate, were HPV16, HPV18, HPV58, HPV45, HPV31 and HPV33. Both HPV 16 and HPV 18 were present in 21% of the cases. Targeting HPV 16 and 18 with prophylactic vaccines could possibly have an important impact on the incidence of invasive cervical carcinoma in this group of women. Primary prevention and cervical cancer screening programmes should be optimized more and run yearly among the general population. It is proposed to screen sex workers when they enter prostitution regardless of their age.
