BACKGROUND More information is needed about time between sexual initiation and human papillomavirus (HPV) infection and development of cervical precancer. METHODS The objectives were to investigate the time between first sexual activity and detection of first cervical HPV infection or development of first cervical intraepithelial neoplasia (CIN), and associated factors in women from the doubl...
OBJECTIVES Previous reports suggest a strong association between human papillomavirus (HPV) and the etiology of laryngeal squamous cell carcinoma (LSCC). However, clinical data regarding the HPV infection rate among LSCC patients remain largely inconsistent. METHODS In total, 674 LSCC patients from three major hospitals in Shanghai were enrolled in this study. We determined the patients' HPV ...
Background: Human papillomavirus (HPV) is responsible for the development of cervical neoplasia. Infection with human papillomavirus type 16 (HPV-16) is a major risk factor for the development of cervical cancer. The virus encodes three oncoproteins (E5, E6 and E7), of which, the E7 oncoprotein is the major protein involved in cell immortalization and transformation o...
Human papillomavirus type 16 (HPV-16) is strongly implicated in the aetiology of premalignant and malignant disease of the cervix. The mechanisms by which HPV-16 induces cell transformation have been the subject of intense investigation for several years. The viral genome encodes three oncoproteins, E5, E6 and E7, but until recently only E6 and E7 were subjected to such scrutiny. The papillomav...
A synthetic E7 gene of human papillomavirus (HPV) type 16 was generated that consists entirely of preferred human codons. Expression analysis of the synthetic E7 gene in human and animal cells showed levels of E7 protein 20- to 100-fold higher than those obtained with wild-type E7. Enhanced expression of E7 protein resulted from highly efficient translation, as well as increased stability of th...
The development of a prophylactic vaccine that targets human papillomaviruses (HPV) 6, 11, 16, and 18 to prevent cervical cancer has increased interest in the ethnic and geographical distributions of HPV genotypes. We investigated HPV prevalence and type distribution by restriction fragment mass polymorphism (RFMP) testing a total of 60,775 specimens (aged 18-79 yr, median 44) taken from liquid...
The majority of human papillomavirus (HPV) belong to the genus alpha-papillomavirus, which can be further subdivided into species and then strains. Approximately 200 strains of HPV have been identified, and the whole genomes of approximately 100 strains have been (discovered) and completely sequenced. Between 13 and 18 HPV strains have been characterized as conferring a high oncogenic risk, wit...
background and objectives : human papillomavirus (hpv) infection is a major risk factor for adenocarcinoma of the cervix. the high-risk types of the virus such as hpv16 and hpv18, which possess the e6 and e7 oncogenes, are responsible for approximately 50% of all cervical cancers. a rapid, sensitive and specific test has been proposed for detection of hpv to improve cervical cancer screening pr...
