چکیده انگلیسی
Epigenetic alterations of human papillomavirus (HPV) genome play an important role in virus life cycle and carcinogenic progression. The aim of the current study was to investigate the correlation between the grade of cervical pathology and DNA methylation status within the L1 gene and the long control region (LCR) of HPV16, HPV18 and HPV51. HPV genomes were analyzed using bisulfite DNA modification procedure with the subsequent amplification of target DNA regions and sequencing. A collection of 202 cervical specimens was analyzed: 157 HPV16-positive specimens, 21 HPV18-positive specimens and 24 HPV51-positive specimens. This study revealed that methylation of CpG was significantly more prevalent in L1 gene as compared to LCR region of all three studied HPV types and the degree of DNA methylation level correlated with the severity of cervical neoplasia. An increased DNA methylation level of HPV16 promoter region in case of cervical cancer was determined.
