Relationship between expression of CDK1,TFF2 and HPV16/18 infection in uterine cervical Carcinomas / 中国医师杂志

ABSTRACT

Objective To investigate the relationship between expression of CDK1,TFF2 and HPV16/18 infection in uterine cervical carcinomas.Methods Formalin-fixed,paraffin-embedded samples including 50 cases of squamous cell carcinomas,20 cases of cervical intraepithelial neoplasia CINⅡ-Ⅲand 20 cases of CINI and 20 cases of normal cervical tissues were studied.Using Polymer DetectionSystem For Immuno-Histological Staining(PV-9000)as immunohisto-chemical detecting method.the expression of TFF2 and CDK1 in these samples were examined.The infections of HPV type 16,18 DNA were determined by PCR.Results There were significant differences for CDK1 between carcinomas,CIN and normal cervices,respectively(all P＜0.05).Expression of CDKl were correlated with tumor grades(P＜0.05).The positive expression of TFF2 in carcinomas was significantly lower than that in normal cervical tissue and CIN.There was significant differences amongthem(P＜0.05).Expression of TFF2 were correlatedwith age(P＜0.05).Thepositive rate of HPV16/18 was significant difference between cervical carcinomas,CIN and normal tissues(P＜0.05),and it was not associated with age,tumor grades,clinical stages and lymph node metastasis(all P＞0.05).The expression of CDK1 was not associated with TFF2 and HPV16/18(all P＞0.05).The expression of HPV16/18 was associated with TFF2(rs=-0.500,P＜0.05).Conclusions The results suggest that in tissues of CIN and cervical carcinomas in TFF2 and CDK1 expression changes and HPVl6/18 infection interact with each other,which can effect the progression of CIN and carcinogenesis of cervical carcinomas.
