HPV-DNA整合状态与宫颈癌发生发展及抑癌基因p53、pRb表达的相关性
Correlation between HPV-DNA integration and cervical cancer development as well as the expression of cancer suppressor gene p53 and pRb
摘要
Abstract
AIM:To analyze the correlation between HPV-DNA integration and cervical cancer development as well as the expression of cancer suppressor gene p53 and pRb,so as to provide new idea for its clinical diagnosis and treatment.METHODS:131 patients with cervical intraepithelial neoplasias (CIN) and cervical cancer which treated with surgery were selected and divided into 4 groups according to disease degree:CIN Ⅰ,CIN Ⅱ,CIN Ⅲ and cervical cancer;at the same time,33 patients with benign tumor were selected as controls.The pathological tissues were extracted and detected HPV-DNA integration using whole genome sequencing and high-throughput virus integrated experiment.According to HPV-DNA integration results,all the patients were divided into 3 groups:multi-integration,single-integration and non-integration,and the p53 and pRb expression levels between groups were compared.RESULTS:The HPV-DNA integration rate increased according to the healthy tissue,CIN Ⅰ,CIN Ⅱ,CIN Ⅲ,cervical cancer in the order,and there was mainly multi-integration in the cervical cancer,and mainly single-integration in CIN and the controls,the difference between groups had statistical significance (P < 0.05).8 types of high-risk HPV-DNA integration,including HPV16,HPV58,HPV18,HPV35,HPV31,HPV33,HPV52 and HPV51 were found,with similar distribution trend in different disease degree.The p53 and pRb positive rate and expression level were different in different integration state,and non-integration group was higher than single-integration group,single-integration group was higher than multi-integration group,the difference between groups had statistical significance (P < 0.05).CONCLUSION:HPV-DNA integration can restrain the expression of p53 and pRb and promote the development of cervical cancer,which may have a certain guiding role for the identification and prognosis evaluation of cervical cancer.关键词
