Abstract:
Objective To explore the correlation of E-cadherin(E-cad) mRNA expression with tumorigenesis and development of lung cancer.Methods The relative quantitative nested RT-PCR was used to detect the expression of E-cad mRNA in cancerous tissues,adjacent and distal tissues of tumor from 50 lung cancer patients,and non-cancerous benign lung tissues from 5 lung disorder patients.Results The means of expression rate of E-cad mRNA in cancerous tissue,adjacent and distal tissues of tumor,and non-cancerous tissues were 1.33?0.53,1.65?0.60,2.01?0.46 and 2.09?0.09 respectively.The data were evaluated by analysis of variance.There were significant difference among cancerous tissue,adjacent and distal tissue(F=18.810,P0.05).Also,there were no significant differences among squamous cell carcinoma,adenocarcinoma and adenosquamous carcinoma in the group of cancerous,adjacent and distal tissue.Conclusion The reduced expression of E-cadherin mRNA may play important role for tumorigenesis and development of lung cancer,and there was no evident relationship of E-cad mRNA with different pathological types of lung cancer.
