Abstract:
Objective To study the role of ARHI protein and COX-2 protein and to explore their correlation in pathogenesis of adenocarcinoma of the uterine cervix.Methods The expression of ARHI and COX-2 protein were detected both in 40 cases of adenocarcinoma of the uterine cervix and in 30 cases of normal cervix by immunohistochemistry.Results The positive rate of the expression of ARHI protein in adenocarcinoma of the uterine cervix was 50.0％ (20/40),which lower than that in normol cervix controls 90.0％ (27/30),the difference was significant ( x2 =12.43,P ＜ 0.05 ) ; The positive rate of the expression of COX-2 protein in adenocarcinoma of the uterine cervix was 82.5 ％ (33/40),which higher than that in normol cervix controls 0 (0/30),the difference was significant (x2 =46.16,P ＜ 0.05 ) ;The positive expression rate of ARHI was negatively correlated with the clinical stage of cervical adenocarcinoma ( x2 =3.96,P ＜ 0.05 ) disease and pathological grade (x2 =7.04,P ＜ 0.05 ).COX-2 protein was positively correlated with pathological grade (x2 =7.04,P ＜0.05 ),but had no correlation with the clinical stage of cervical adenocarcinomacervical adenocarcinoma stage of diseas(P ＞ 0.05) ;The expression of ARHI protein and COX-2 protein wasn't correlated with lymph nodeatic meatastasis(P ＞ 0.05);The expression of ARHI protein had correlation with the expression of COX-2 protein (r =0.31,P ＜ 0.05 ).Conclusion Inactivation of ARHI gene and the abnormal expression of COX-2 protein are involved in the origin of cervical adenocarcinoma,their synergistic reaction may play an important role in tumor origin of cervical adenocarcinoma.
