Relationship of high-risk human papillomavirus infection and c-jun and c-fos expression in cervical carcinoma / 临床与实验病理学杂志

ABSTRACT

Purpose To investigate the relationship and clinical significance of high-risk human papillomavirus infection and expression of c-jun and c-fos protein in cervical carcinoma.Methods Cervista HR-HPV testing,immunohistochemical SP method were employed to detect the infection of HR-HPV,c-jun and c-fos protein in 70 cases of CSCC,60 cases of cervical intraepithelial neoplasia and 20 cases of chronic cervicitis.The correlation between c-jun and c-fos protein expression and of HR-HPV infection was analyzed.Results Of the 70 cases of CSCC,the positive HR-HPV was 69 cases,the positive rate in HR-HPV in A9 group was the highest (85％,59/69).The positive expression of c-jun and c-fos were 80％ (56/70),85.7％ (60/70) in 70 cases CSCC,70％ (21/30) and 70％ (21/30) in 30 cases of cervical high grade intraepithelial neoplasia,and 20％ (6/30),23.3％ (7/30) in 30 cases cervical low grade intraepithelial neoplasia,but the positive expression rates of c-jun and c-fos in the 20 cases of chronic cervicitis were 0.Expression of c-jun and c-fos in cervical cancer group was higher than that in the chronic cervicitis group and low grade intraepithelial neoplasia (P ＜ 0.05).The expression of c-jun and c-fos was statistically significant in different groups of clinical stage and pathologic grading in the CSCC (P ＜ 0.05).Additionally,the expression of c-jun and c-fos was positively correlated with the infection of HR-HPV in CSCC (P ＜ 0.01).Conclusion The infection of HR-HPV has significant subtype-specific and has a positive correlation with the expression of c-jun and c-fos in CSCC,which suggests that AP-1 pathway activation after HRHPV infection may be associated with the occurrence and development of cervical carcinoma.
