Expression and Clinical Significance of KIF11,β-catenin and GSK-3β in Cervical Cancer / 医学研究杂志

ABSTRACT

Objective To investigate the expression of kinesin family member 11(KIF11),β-catenin and glycogen synthase ki-nase-3β(GSK-3β)in cervical cancer and its clinical significance.Methods The expression of KIF11,β-catenin and GSK-3β in 102 cases of cervical cancer,52 cases of high-grade squamous intraepithelial lesion(HSIL)and 46 cases of low-grade squamous intra-epithelial lesion(LSIL)and 40 cases of chronic cervicitis were detected by immunohistochemistry,to analyze the relationship between the expression of the three indicators and the clinicopathological characteristics of cervical cancer patients,and to analyze the correlation be-tween the three indicators.COX proportional hazards model was used to analyze the prognostic factors of cervical cancer patients.Results With the progression of cervical lesions,the positive rates of KIF1 1 and β-catenin increased gradually,while the positive rates of GSK-3β decreased gradually(P＜0.05).The positive expressions of KIF11,β-catenin and GSK-3β in cervical cancer tissues were significantly different in International Federation of Gynecology and Obstetrics(FIGO)stage,differentiation degree and lymph node metastasis(P＜0.05),but there was no significant difference among different ages and pathological types(P＞0.05).The expression level of KIF11 was positively correlated with β-catenin(r=0.461,P＜0.05),and the expression level of β-catenin was negatively correlated with GSK-3β(r=-0.692,P＜0.05).The expression level of KIF11 was negatively correlated with GSK-3β(r=-0.336,P＜0.05).The average survival time of patients with positive expression of KIF11 and β-catenin was shorter than that of pa-tients with negative expression,and the average survival time of patients with positive expression of GSK-3 β was longer than that of pa-tients with negative expression of GSK-3β.COX regression analysis showed that FIGO stage,lymph node metastasis,KIF11 and β-catenin were independent risk factors for the prognosis of cervical cancer patients,and GSK-3β was an independent protective factor.Conclusion KIF11,β-catenin and GSK-3β are abnormally expressed in the tissues of cervical cancer patients.KIF11 may be in-volved in the regulation of Wnt/β-catenin pathway in the development of cervical cancer.The combined detection of KIF11 may provide a new reference for the diagnosis and prognosis of cervical cancer.
