Eyes Absent （EYA） is an important and conserved transcriptional regulator of development. The aim of the present study was to identify the expression of Drosophila Eyes Absent Hemologue 2 （EYA2） in non-small cell lung cancer （NSCLC） and to investigate their correlation with clinical parameters. Methods： Fresh, paired lung samples （n = 59） of NSCLC were obtained by surgical resection at the Department of Thoracic Surgery of the People＇s Liberation Army General Hospital. Expression of EYA2 were examined by Western blot and immunohistochemical analysis in specimens of NSCLC and paired normal lung tissue. Clinical data, pathologic result and Ki67 expression were collected and subsequent correlation with EYA2 expression was analyzed. Results： EYA2 expression was found located in cytoplasm and nucleus, but mostly in cytoplasm. The expression of EYA2 increased in NSCLC by Western blot and immunohistochemistry, which was correlated with histology type, but not correlated with gender, age, pTNM stage, histological differentiation and lymph node metastasis. Compared with normal lung tissue, the expression of EYA2 significantly was up-regulated in lung adenocarcinoma, while no significant difference in lung squamous cell carcinoma. Expression of EYA2 was uncorrelated with expression of Ki67 in NSCLC. Conclusion： Expression of EYA2 was augmented in lung adenocarcinoma. EYA2 is likely participating in tumorigenesis and development of lung adenocarcinoma as transcriptional activator.展开更多
