Objective:To investigate the expression of DKK-1 and β-catenin in non-small cell lung cancer and their correlation.Methods:The expression of DKK-1 and β-catenin were detected in pathological tissue sections from 60 patinets with non-small cell lung cancer by immunohistochemical SP method
and their clinical pathological features were analyzed statistically.Results:The positive expression rate of DKK-1 and the abnormal expression rate of β-catenin in non-small cell lung cancer tissue sections were 25.0%(15/60) and 71.7%(43/60)
respectively.The expression of DKK-1 was significantly associated with the degree of tumour differentiation
clinical stage and lymph node metastasis(P<0.05).The expression of β-catenin was significantly associated with the degree of tumour differentiation(P<0.05).There was association between the expression of DKK-1 and β-catenin in non-small cell lung cancer(P<0.05).Conclusion:The loss expression of DKK-1 may contribute to the progress of non-small cell lung cancer.Its effect on β-catenin may be one of the pathways for it to work.
