Genome-wide profiling of the human papillomavirus DNA integration in cervical intraepithelial neoplasia and normal cervical epithelium by HPV capture technology.


ABSTRACT: HPV integration plays an important role in cervical carcinogenesis. HPV genotypes and the exact integration sites were investigated using HPV capture technology combined with next generation sequencing in 166 women. Three, one and six integration sites were verified in 7 HPV-positive 'normal cervical epithelium', 6 HPV-positive CIN2 and 15 HPV-positive CIN 3 samples, respectively. Of the 10 integrations, one and nine were involved with HPV33 and HPV16, respectively. Our study accurately evaluated HPV integration level in CINs and normal cervical tissues using high-throughput viral integration detection method providing basic evidence for HPV integration-driven cervical carcinogenesis.
