Abstract: Objective To investigate the relationship between the expression of DEK and Hpa infection in uterine cervical carcinogenisis.Methods Formalin-fixed,paraffin-embedded samples including 45 cases of squamous cell carcinomas,25 cases of cervical intraepithelial neoplasia CINⅢ,and 20 cases of CINI-Ⅱ,10 cases of normal cervical tissues were studied using polymer detection system for immunohistochemical technique to examine the expression of DEK and Hpa.Results The positive ratios of DEK in cancer tissues,normal cervical intraepithelial lesions,normal cervical tissues positive rates were 88.9%,24.4%,10.0%,respectively.The positive ratio of expressions of DEK in cervical carcinomas was significantly higher than CIN and normal cervical tissues (x2 =38.054,P <0.01 ;x2 =5.774,P <0.05).The positive ratios of expressions of Hpa in normal cervical tissues,CIN and cervical cancers were 75.6%,24.4% and 10.0%,respectively.The positive ratio of expressions of Hpa in cervical carcinomas was significantly higher than CIN and normal cervical tissues ( x2 =31.69,P < 0.01 ; x2 =12.94,P < 0.01 ).The expression of DEK and Hpa in cervical lesions was highly related in the cervical cancer tissues( r =0.617,P =0.001 ).Conclusions DEK and Hpa possibly played an important role in the development of cervical cancer.Cervical intraepithelial lesions and cervical carcinoma might be associated with changes in the expression of DEK and Hpa,and interact together to influence the development of CIN and cervical cancer.
