Abstract:
Objective To study the different expressions of cancerous inhibitor of protein phosphatase 2A (CIP2A)in non-small cell lung cancer (NSCLC),investigate its clinical significance and potential prognostic value.Methods Immunohistochemical and real-time polymerase chain reaction (PCR)were used to detect the expressions of CIP2A mRNA and protein in two groups of sixty paired NSCLC specimens and adjacent non-cancer tissues.The relationship between its expression and clinical pathological data and prognostic factors were analysed. Results The expression of CIP2A mRNA in NSCLC specimens was higher than those in adjacent non-cancer tissues(P<0.01 );The expression of CIP2A protein in NSCLC tissues was significantly higher than that in the corresponding adjacent non-cancer tissues (P<0.01 ).The expression of CIP2A was closely correlated with the differentiation and lymph node metastasis of NSCLC tissues (P<0.05 ),while incorrelated with sex,age,pathematology type,tumor size and tumor node metastasis (TNM)stage.Conclusion CIP2A highly expresses in NSCLC,and the expression of CIP2A will increase with the differentiation and lymph node metastasis of NSCLC tissues.The expression of CIP2A and lymph node metastasis can be used as an independent risk factor for the prognosis of patients with NSCLC.
