Expression and significance of DDX43 in lung adenocarcinoma.

This paper aims to determine the expression and clinical significance of DDX43 in lung adenocarcinoma. Expression of DDX43 gene and protein of lung adenocarcinoma tissue and para-carcinoma tissues was observed in 27 cases by RT-PCR and immunohistochemistry. These patients were diagnosed as lung adenocarcinoma in the Huaihe Hospital of Henan University from February 2015 to December 2015. The relative ratio of DDX43 mRNA expression in lung adenocarcinoma and para-carcinoma tissues was 0.87±0.62 versus 0.21±0.77 and the difference between the two groups was statistically significant (P<0.01). The expression of DDX43 in normal lung tissues and lung adenocarcinoma tissues was different. The positive rate of DDX43 expression in lung adenocarcinoma tissues was significantly higher than that in normal lung tissues, and the difference was statistically significant (P<0.05). The analysis of clinical pathological characteristics showed that the increase of protein expression was related to the stage and metastasis of lung adenocarcinoma. DDX43 is highly expressed in lung adenocarcinoma, and the expression level is related to the stage and metastasis of lung adenocarcinoma, suggesting that DDX43 is closely related to the occurrence and development of lung adenocarcinoma, and may be a molecular marker for early diagnosis of lung adenocarcinoma.
