Methylation status of HPV16 E2‐binding sites classifies subtypes of HPV‐associated oropharyngeal cancers
2 Mar 2015
Abstract excerpt
BACKGROUND: The human papillomavirus (HPV) E2 protein is a transcriptional repressor of the oncogenes E6/E7 and loss of E2 function is considered a key step in carcinogenesis. Integration of HPV into the host genome may disrupt the E2 gene. Furthermore, methylation of CpG dinucleotides in E2-binding sites (E2BSs) in the HPV upstream regulatory region may interfere with transcriptional repression of E6 and E7 by...
