ABSTRACT

OBJECTIVE: L and E6/E7 gene amplification analyses were compared to identify human papillomavirus (HPV) infection and verify the HPV type, with the intent to minimize HPV typing errors. METHODS: L1 gene verified HPV typing was accomplished via polymerase chain reaction (PCR) and membrane assays. Verification of HPV typing via E6/E7 genes was accomplished through nested multiplexed PCR. The results from 104 samples were compared. RESULTS: The rates of accordance and difference were 35% and 65%, respectively. For 29% of the analyses, nested multiplexed PCR was more diversified than the membrane assay. CONCLUSION: HPV can be classified into low-risk HPV and high-risk HPV groups. In parallel amplifications of the L and E genes is more efficient for accurate diagnosis in light of the different symptoms and attendant precautions of the risk groups.

ABSTRACT

Objective To investigate the gene sequence and mutations of human papillomavirus(HPV)type16E6E7in patients with HPV infection in Beijing.Methods Sample DNA was extracted from lesions in patients with HPV infection.HPV types were identified by polymerase chain reaction(PCR).E6E7gene,isolated from samples infected with HPV16only,was cloned into plasmid pGEM-3zf and sequenced.Results The recombinant plasmid pGEM/16E6E7was constructed successfully.The whole HPV E6E7gene was776bp in length which was equal to that of the standard strain.Three nucleotides exchanges,i.e.,p60PROE6,p96GLUE6,p565SERE7,were found in E6E7gene.Conclusion The data suggest that there are nucleotide differences of HPV E6E7gene between HPV obtained from Beijing and that of standard sequence.
