Human papillomavirus (HPV) DNA has been identified in esophageal carcinomas. However, the incidence of HPV varies significantly in different geographical locations. In this study, neoplasms from Turkmen Sahra, a region in Golestan province in northeast part of Iran, with a high incidence of squamous cell carcinoma were analyzed for the presence of HPV DNA. Turkmen Sahra is located in the cancer...

results human papillomavirus was found in 62.1% of the samples obtained from the patients. among the hr and lr types, hpv-6 was the major genotype 64.8%. type 16 and 18 were the most frequent hr-hpv types (presented in 26% of the patient), followed by type 50s (24.7%), 45, 30s, and 11 (1.8% from each). multiple hpv infections were presented in 40.7% of the positive genotyping specimens. backgro...

The expression of human papillomavirus type 16 late genes encoding virus capsid proteins L1 and L2 is restricted to terminally differentiated epithelial cells in the superficial layers of the squamous epithelium. We wish to understand the molecular mechanisms that determine the levels of expression of the human papillomavirus type 16 late genes. We have previously shown that the L1 coding regio...

Human papillomavirus-16 (HPV-16) viral load could be a biomarker predictive of the presence of high-grade cervical lesions. Recently, several real-time PCR assays have been developed to accurately measure HPV-16 viral load. However, results from various reports using these assays cannot be compared because interassay test correlation has not been documented. The variability of HPV-16 DNA quanti...

Human papillomavirus (HPV) infection, in particular that by HPV type 16, is positively associated with cervical/genital cancer. In contrast, human adeno-associated virus (AAV) infection is negatively associated with these same cancers. AAV has also been found to inhibit the oncogenic properties of a variety of DNA viruses, including bovine papillomavirus type 1, a relative of HPV-16. Taken toge...
