The HPV16 E1∧E4 protein is thought to contribute to the release of newly formed viral particles from infected epithelia. In order to investigate amino acid mutations in the HPV16 E1∧E4 protein, the complete E4 ORF was amplified by PCR in 27 HPV16-positive cervical samples, and the amplicons were cloned. Fifteen nucleic acid variations were identified in the(More)
The E2 gene of human papilloma virus is expressed at the early stage of the viral life cycle, encoding the E2 transcription factor, and regulates the expression of E6 and E7 oncogenes. Disruption of E2 gene due to viral integration inhibits the transcriptional suppression of the HPV oncogenes, inducing cell proliferation. In the present study, a total of 22(More)
