Expression of Aurora-A,MCM7 and HPV 16 E7 in uterine cervical squamous cell carcinoma and their relationship with clinicopathological factors

Purpose To explore the expression of Aurora kinase A( Aurora-A),minichromosome maintenance protein 7( MCM7) and human papillomavirus type 16 E7 protein( HPV 16 E7) in uterine cervical squamous cell carcinoma( CSCC) and to investigate their relationship with clinicopathological factors. Methods Immunohistochemical method was employed on 20 cases of low-grade cervical intraepithelial neoplasia( CIN1),30 cases of high-grade cervical intraepithelial neoplasia( CIN2 + 3),40 cases of CSCC,and 20 cases of chronic cervicitis. Results( 1) Aurora-A localized in the cytoplasm and nucleus. MCM7 protein positive staining localized in the nucleus. In the nucleus,and( or) the cytoplasm appeared brown particles positive for HPV 16 E7.( 2) The expression of AuroraA,MCM7 and HPV 16 E7 were higher in the group of CIN2 + 3 and CSCC than that in the group of chronic cervicitis or CIN1( P 0. 0083).( 3) In cervical cancer,the expression of Aurora-A,HPV 16 E7 showed positive correlation( P 0. 001,rs= 0. 657). The expression of MCM7,HPV 16 E7 showed positive correlation( P 0. 001,rs= 0. 616). The expression of Aurora-A,MCM7 showed positive correlation( P 0. 001,rs= 0. 597).( 4) Aurora-A expression levels was associated with tumor cell differentiation,clinical stage and lymph node metastasis( P 0. 05). MCM7 expression levels was associated with tumor cell differentiation and clinical stage( P 0. 05). HPV 16 E7 expression had no correlation with patient age,tumor size,tumor differentiation,clinical stage and lymph node metastasis( P 0. 05). Conclusion Aurora-A,MCM7 and HPV 16 E7 expression are gradually increased with disease progression,and closely related to the occurrence and development of cervical cancer,they are expected to be early diagnosis,early treatment of biological indicators of cervical cancer.
