Methods： The expressions of Ets-1 mRNA, and TGFβ1 and c-Met proteins were detected in 89 primary lung cancers, 12 lung cancer with lymph-node metastasis and 12 precancerous lesions by FISH（fluorescence in situ hybridization） and immunohistochemical method, and 10 normal lung tissues were used as controls. Results： The expressions of Ets-1 rnRNA, and TGFβ1 and c-Met proteins were significantly higher in 89 primary lung cancer than in the control group （P〈0.05）. The expressions of Ets-1 mRNA, and TGFβ1 and c-Met proteins were related to lymph node metastasis and clinical stages. There was a positive correlation between the Ets-1 mRNA expression and TGFβ1 and c-Met proteins （P〈0.05）. Conclusion： Ets-1 mRNA, TGFβ1 and c-Met proteins may be related to the pathogenesis, progression and malignant behavior of lung cancer. They may play an important role in prognosis assessment of lung cancer.展开更多
