[Expression and significance of UNC-112 protein in lung cancer].

OBJECTIVE: To investigate the expression of UNC-112 protein in lung cancer and discuss its value. METHODS: The method of immunohistochemical SP was employed to detect the expression of UNC-112 protein in 210 cases of lung cancer, and evaluate its correlation with pathological classification. RESULTS: UNC-112A and UNC-112B protein were highly expressed in non-small cell lung cancer, not expressed or expressed at very low levels in small cell lung cancer(P < 0.05);the expression of UNC-112A protein in squamous cell carcinoma was significantly higher than those in adenocarcinoma (P < 0.001)and large cell lung cancer (P < 0.01), but there is no significant difference between adenocarcinoma and large cell lung cancer (P = 0.18).UNC-112A protein expression level was positively correlated with the differentiation of squamous cell carcinoma(P = 0.0024). The expression of UNC-112B protein was significantly higher in large cell lung cancer than those in adenocarcinoma (P = 0.002) and squamous cell carcinoma (P < 0.01), and it was significantly higher in adenocarcinoma than squamous cell carcinoma (P = 0.005). CONCLUSIONS: UNC-112 protein may be related to the heterogeneity of lung cancer, UNC-112A and UNC-112B protein play different roles in invasion and migration of lung cancer.
