Evaluation of E-cadherin gene expression in cervical carcinomas
Epithelial adhesion molecule, E-cadherin plays important role in maintaining structural integrity of epithelial tissue. Altered expression of E-cadherin might result in the loss of contact inhibition growth property, abnormal cell growth and differentiation, hence the oncogenic transformation. To explore the role of E-cadherin in the tumor progression, we have investigate the expression pattern of E-cadherin in invasive cervical carcinomas. 77 paraffin embedded specimen with FIGO staging Ia¡]N=15¡^, Ib¡]N=19¡^, Ib meta¡]N=13¡^ IIa¡]N=17¡^, IIb¡]N=13¡^were included in immunohistochemical study, 18 surgical removed tumor tissues of Ib stage and its normal counter parts were used for semi-quantitative RT-PCR analysis. The results indicated that no significant correlation between E-cadherin expression level and tumor metasis, patient prognosis. However, E-cadherin immunostainimg intensity was significanty inverse correlated with tumor size¡]p < 0.001¡^. Notably, loss of membranes E-cadherin expression might be a significant factor that correlated with tumor metasis¡]p = 0.001,< 0.005¡^.
